Drinking and farming work better. The purpose of the research is to evaluate the environment of successive dams in the river bed and also its effects on environmental factors in the region. Materials and Methods: In this research, it tried to investigate the environmental evaluation of successive small dams in the river course of Karin region of Fars province and to determine the positive and negative points of the construction of successive dams using Leopold's matrix. Three physical, biological, economic, social and cultural states were studied and evaluated in two phases of construction and operation with option 1 (not doing the project) and option 2 (doing the project). Results and Discussion: The assessment of environmental effects in the biological part of option 1 shows that the total score of the construction and operation phase has obtained a score of -212, which has the greatest negative impact on the factors of animal species mortality, reduction of biological food and growth and breeding of aquatic animals, and destruction. Vegetation can be seen in option 2 (execution of the project) on biological activities. It shows that the sum of points for the construction and operation phase has scored +295, which is the most effective factors of animal species migration, impact on the food chain and growth and development. Vegetation and aquatic cover. Conclusion: A general review of all environmental factors, although the option of not implementing the project has a negative score of 138, but not doing the project and leaving the area to itself is actually not using natural resources and not moving towards sustainable development. In the total scores of the entire economic, social and cultural environment, it was concluded that with the effect score of +2107, this action can have an effect on the economic, social and cultural prosperity of the region in the future, as well as the construction of successive dams, in addition to the change in the region's ecosystem, will cause Economic prosperity and water quality and quantity.

Hence, different parts of an urban project management improvement are one of city executive concerns. Delay and Delay management is on of these parts. Any delay of construction project implementations is a waste of resources and it will impose heavy costs on any project. Occasionally, this is so influential that it even affects project justification. This paper examines the causes of urban project delays by using Casual Layered Analysis (CLA). Then, it will use scenario-building to make most likely scenarios by using Global Business Network (GBN). GBN uses the most likely uncertainties ahead of project delay to make its scenarios. In this regard, two series of interviews, one structured and one structured, are performed. Then, based on them, The related uncertainties are ranked by using fuzzy Technique to Order Preferences by Similarity to Ideal Solution (TOSIS). It uses SWOT to propose some strategies. Based on results, four scenarios are formed. Then, the impact of each scenario on the project delay conditions are examined. Some strategies are suggested to move toward the best scenarios. Based on the results, minimizing the government size and creating various infrastructures ,to make competence situation, are the future keys of having less delayed urban project. Manuscript profile -

Development catalyst projects are no exception to this rule. In recent years, with the increase of these projects, It is necessary to study the views of citizens of the neighborhoods targeted for regeneration as the main stakeholders of these projects. The current study aims to determine the effectiveness of the match factory revitalization project in improving the quality of the neighborhood to measure the perceptions and expectations of neighborhood residents of the dimensions and factors of local development and catalyst. This research is of applied type and has been prepared by evaluation method with gap analysis model, and its statistical population consists of residents and businesses over 18 years of age in the Koochamshki neighborhood. The sample size was determined using Cochran's formula and simple random method, 384 people. The required information was collected through library and survey studies using a questionnaire and analyzed using ANOVA and T-Test. The results indicate a high score of respondents 'expectations from the three dimensions of development and catalyst (4.23) and a low score of their perception (3.26), which shows that there is a difference between residents' perceptions and expectations after the revival of the match factory. Also, the existence of a significant gap (-0.97) between residents' perceptions and expectations of the dimensions and factors of development and catalyst in this neighborhood confirms the second hypothesis of the research. Calculating the difference between the average score of residents' perceptions and expectations among the factors also shows that the largest gap belongs to the factor of "residential dignity" (-1.48) and the lowest gap belongs to the factor of "physical and environmental status of housing" (-0.4). dedicated. The findings also indicate that there is a significant difference between the expectations and perceptions of respondents in terms of their residency, but in relation to the gender of respondents, despite the gap between the views of both sexes, no significant difference in terms of perception and expectation was found between men and women. An important issue in findings is the negative gap in all dimensions and factors studied which shows the failure of planners to meet residents' expectations of changes effected by the catalyst project. Observations and field studies show that after the implementation of this project, growing events have taken place in this neighborhood; But analytical studies indicate that the implementation of this project has not yet been able to meet the demands and needs of neighborhood residents. The research findings indicate the existence of a gap between residents' perceptions and expectations of development factors in this neighborhood, which is statistically significant. An important issue in the research findings is the negative gap in all dimensions and factors studied, which shows the failure of planners to meet residents' expectations of changes effected by the local development catalyst project. In order to increase the residents' satisfaction, the factors with more gaps should be prioritized and measures should be taken to reduce the desired gap. Manuscript profile -

In particular, L0(Г)=Г and L1(Г)=L(Г) is the line graph of Г. The toroidality (and projectivity) index of a graph Г is the smallest integer k such that the kth iterated line graph of Г is non-toroidal (and non-projective). We denote the toroidality index of a graph Г by ξT and the projectivity index of a graph Г by ξP. If LK(Г) is toroidal (and projective) for all k≥0, we define ξT=∞ (and ξP=∞). Let R be a commutative ring with nonzero identity. Then the Jacobson graph of R, denoted by 𝔍R, is defined as a simple graph with vertex set RJ(R) such that two distinct vertices x and y are adjacent if and only if 1 - xy is not a unit of R. In this paper, we study the toroidality and projectivity indices of Jacobson graphs. We give full characterization of this graph with respect to its toroidality and projectivity indices. Moreover, the toroidality and projectivity index of Jacobson graph is either infinite or two. Manuscript profile -

Various approaches to data envelopment analysis have been presented so far to provide a good tool for evaluating the efficiency of units in uncertain situations, including random, fuzzy and robust approaches. In a situation where the probability distribution function of random variables is known, stochastic approach is a precise solution for problem solving. Nevertheless, previous research in this field has focused on the transformation of a random problem into a definite problem. In this research, a method for modeling data envelopment analysis is presented using computer programming. In this method, random processes are simulated, and finally, the performance distribution function is presented instead of a definite number as the unit's efficiency. In this model, a new concept is presented as the probability of efficiency, which represents the probability that the unit will be located on the efficient boundary. The proposed method is empirically applied in a real case of selecting research and development projects. Manuscript profile -

In this article, we examine the scheduling assignment of medical teams to the patients with a new innovative approach based on resource constrained project scheduling problem. Advantages of proposed approach can be included the use of theorems, standard benchmark problems, and various (meta-innovative) scheduling methods to improve assignment quality, as well as determining the minimum number of human resources required to cover all medical services requested by patients. In this approach, we solve the HHC problem by defining a dynamic priority rule and using the parallel scheduling scheme. Evaluation criteria for evaluating the quality of feasible solutions resulting from scheduling include minimizing the travel time of medical team members, reducing overtimes, maximizing the number of human resources which are used, and so on. The set of feasible solutions satisfy to some constraints such as the total working time in the contracts, the hardware time window of each job, the mandatory breaking time, and the optimal assignment of the medical team to patients (according to the type of service requested by the patient). The numerical results obtained from calling the proposed algorithm on the Kolisch’s benchmarks are presented to evaluate the performance of proposed approach. Based on the results, the proposed algorithm has a high ability to solve the HHC problem. Manuscript profile -

MoreProject-oriented organizations are one of the emerging organizational forms that are formed around projects and teams. These organizations have dynamic boundaries and fields of works, in which the number and size of projects of the organization are constantly changing. In this regard, the managers of these organizations are always faced with the issue of choosing the higher economic justification projects for their organizations, as well as, resource management (including resource leveling and resources allocation) for the selected projects. In this research, a mathematical model of renewable and non-renewable resource management for self-financing project-oriented organizations is presented. This means that financing of the selected projects within the organization is limited to the initial capital and the incomes of the completed projects. In this regard, the project portfolio theory is used to solve the problem of the selection and scheduling of the projects within the project-oriented organization considering the limitation of renewable and non-renewable resources, the existence of a prerequisite relationship between project activities, the time value of capital for financial resources and finally the application of reinvestment strategy. The multi-objective function maximizes the net present value of the investment as well as minimizes the amount of the idle renewable resources. The modeling is a mixed integer programming and after linearization of the model, the LP-metric method is used to solve the multi-objective function, and finally the results are examined on a numerical example.

This can lead to a modified function projective synchronization between two complex chaotic systems with completely unknown parameters. Also, the error of estimating the parameters and the value of the coupling strength is accurately expressed using the proposed method.‎‎Because in the modified projective synchronization (MPS) and function projective synchronization (FPS) methods, fixed coupling strength is considered, this limits the range of applications of these methods. MFPS is, therefore, a more general definition of MPS and FPS when the scaling function matrix is chosen by a constant matrix and a scaling function, respectively. This method can be used on other complex dynamic systems. Numerical simulations are presented to show the effectiveness and validity of the above theoretical results. Manuscript profile -

Main identified risks in this study are project financing risk(equity ratio risk)and the risk of revenue of project. In order to model the risks, we used the MartingaleVariance Model (MVM) for the revenue risk and the Triangular distribution function forthe equity ratio risk. We applicated the Monte Carlo simulations method for obtainingthe probability distribution function and critical values of the decision index (Net PresentValue, Internal Rate of Return, Debt Service Coverage Ratio). The one of thermal powerplant projects data prepared by MAPNA, has been implemented in this study. The resultsof the simulation indicate that the risk of negative NPV of project is 13.41 percent and therisk of DSCR lower than 1.2 is 8.65 percent.

Since governmentsare aimed to give services more efficiently and with higher quality, they are doingrelated works and attempts in order to facilitate and accelerate the said projects.Experiences of different countries show that factors such as lack of financialresources, budgetary deficit of the governments for financing big projects and highdemand for investing in these projects have lead countries to do their attempts to fulfilpartnership of the private sector and make suitable competitive climate for theircooperation. These attempts have result in Public-Private Partnership (PPP) andfacilitated the growth and development of the countries. In this study, the relationshipbetween the factors influencing the utilization of PPP in 21 countries during 2000-2008 using panel data method are studied. The results show that countries’ revenue,economic stability, budget deficit and underground sources are the main factorsinfluencing public private partnerships in the studied countries. Finally, the model forpublic private partnerships has been generated. Manuscript profile -

In competitive or highly uncertain projects, it is not possible to control the momentum of the project's profit and loss, and, it is not possible to accurately identify the activities causing profit or loss and the extent of their impact on these results.After a literature review, a method developed to control the momentum of direct and overhead costs of the project during its progress. An interview was conducted with 26 financial managers in construction companies during 2 to 4 times using goal-oriented and bullet-proof methods from June 2016 to May 2017 with the aim of validating and modifying the method. According to a semi-structured interview analysis, the proposed method contributed to increasing the precision, certainty, traceability of overhead costs that is about 10 to 35 percent, and provided the integrity of the financial, technical and operational system. It also facilitates rooted deviations, and reduces costs by considering Activity-driven Competitive and strategic conditions. It's also limiting the target cost of working packs and causing an alarm on the completion of each department's budget and analyze its reasons, allowing for control of budget deviations. Also, according to Friedman test, there is a meaningful competitive ability compared to the conventional cost control method in the projects. Manuscript profile -

The research method was a survey-field study. The statistical population of the study included 54 ranchers in the pastures of Hamze Chal, Leman Sofla and Olia of Kojour, and the sample size was determined for 45 individuals based on Cochran formula and 28 of them collaborated in the research. Samples were selected by a simple random sampling method and the essential information was collected through a questionnaire. Data analysis was done by SPSSv19 using Pearson and Spearman's correlation coefficient, Spearman, and multivariate regression. The results of the research showed that the rate of participation in rangeland projects was high, but no significant correlation was observed between the age of respondents and the level of their education with the rate of participation in rangeland projects. Besides, there is a significant and positive correlation between the rate of income and the rate of participation in rangeland projects with a probability of more than 95% and there was a significant relationship between the level of trust in government promises and participation in rangeland projects. Regression analysis indicated that the variable of knowledge in rangeland management projects had a greater contribution in predicting the participation rate in rangeland management projects compared to other variables. Also, holding training-extension classes led to an increase in the motivation of participation and also raising problems and issues by experts and managers for rangeland projects caused to reduce the rate of participation in rangeland projects. According to the results of this study, increasing the awareness of ranchers, increasing the level of trust to the government, reducing problems, and increasing the income of ranchers can be suggested as a solution.

Underground construction projects face characteristics like underground situations, the large size, large amount of funding, various stakeholders, long project duration, and complicated construction techniques. As various stakeholders are involved in metro projects, the interaction among stakeholders lead to complicated risk management process in these type of projects. Therefore, we used social network analysis to investigate social risks related to metro construction projects, from a stakeholder perspective. Method: Using qualitative research approach and interview strategy, we gathered the data from 30 stakeholders that classified in six stakeholder groups. The data were analyzed using social network analysis seawares and the social network of stakeholder’s risks were depicted. Results: Human-management, planning, financial-economic, legal, and project delays are the most critical risks in metro projects. Conclusion: Based on the findings, it is concluded that financial and economic risks are not always prioritized over project risks, and special attention should be paid to human and managerial risks, along with other risks.

In this research, based on a survey study, the participation and satisfaction of the citizens from construction projects performed by the municipality have been studied by a questionnaire. During this research, 127 citizens representing 46940 families residing in district 3, region 5 of Tehran municipality, were randomly selected by the use of Cochran’s sampling formula. According to the results, the amount of citizens’ awareness about the construction projects is at a high level. Also the significance of construction projects such as “surface runoff drainage”, “street construction", "construction of a sport complex” and so on in responders’ view is more than dealing with projects such as “construction of a retaining wall in the region’s passages” and “construction of quarters' center”. However, the citizens’ satisfaction about the performance of the municipality in implementing the construction projects is at a high level. Also from the citizens’ point of view, the mass media is a good vehicle for notification about the municipality construction projects. And the quarters' center plays a minor role in this context. In this regard, enhancing the tools of the communicating systems 137 and 1888 by the municipality is of high significance. In sum, based on these results, the amount of satisfaction, awareness and partnership of the citizens in municipality construction activities is at a high level and it can be concluded that the municipality construction projects are highly in alignment with citizens’ need.

By considering the data of closest target and utilizing it appropriately, the decision making unit (DMU) under evaluation determines how to transform its inputs and outputs to become efficient. Also, traditional DEA models only utilize the external inputs to produce the final outputs in evaluating the relative efficiency of decision making units (DMUs), and internal operations are not be considered. Therefore, traditional models can not accurately determine the source of inefficiency inside the structures. To overcome this problem, different authors proposed various network DEA models (NDEA). This paper is an attempt to find the closest target in various scenarios of network DEA. The study concerns about different existed scenarios in network DEA models and proposes specific models to find closest targets in each scenario. Also, an empirical example has been presented to illustrate the proposed models. Manuscript profile -

The results showed that the largest decrease in discharge in summer will be 27%, while the increase in surface runoff in winter is expected to be 12%. The reason for this is the continuation of global warming, which will lead to faster melting of winter snow. The results of the models indicated a decrease in groundwater level in all months of the year in future periods, which has been significant in all periods-scenarios. The groundwater level will decrease between, on average, 1.2m to 3.2m. Reduction rainfall and discharge in the summer - which coincides with the growing season - will also intensify the increase in groundwater harvesting. This will exacerbate the water crisis in the region. Manuscript profile -

The previous methods to estimate IDF curves are time consuming. In addition, they required many input parameters that tend to reduce their reliability. In previous methods, rainfall data should be recorded in different durations to extract the IDF curves. In some regions, only 24-hour rainfall data are recorded that they cannot build the IDF curves. In this study, temporal scaling properties of rainfall were used to extract the IDF curves for short durations from daily rainfall data. The used method has less complex stages and less number of parameters compares to previous methods. The proposed method was used in Saveh hydro-meteorological station as a case study and the results indicated its reasonable accuracy. Manuscript profile -

Road construction in the forest, will change the photometry characteristics of the canopy. Therefore, this study aimed to investigate the LAI values and canopy cover along the secondary forest roads and compare with the value of mentioned characteristics in the Beech-Hornbeam forest type.Material and Methodology: This study was conducted in district 1 of Langa Forestry Project in Kelardasht. In the logged parcel, 10 transects were established randomly and perpendicular to the road at fillslope was constructed on 1984. On July 2019, the canopy was photographed by hemispherical photography at distances of zero (road edge), 15, 45, 75 and 105 meters. Then, the values of the mentioned characteristics were processed in GLA software based on the fourth ring of this software.Findings: According to the ANOVA test, the values of canopy cover and LAI are different between different distances of forest roads and according to the Tukey test, the values of the mentioned characteristics at the distance of zero meters from the road (road edge) is significantly lower than other distances (p < 0.001).Discussion and conclusion: Due to the fact, this road is one of the secondary forest roads, so traffic is rare on this road, and on the other hand, a single selection cutting method (with low interference intensity) was used in this forest. Therefore, the forest in this area over time has been able to mitigate the negative effects of road construction and only at the road edge has a significant effect on the values of these characteristics.

In this study, the economic and environmental impacts of Iran-Eurasia free trade agreements were analyzed by RunDynam software in two scenarios (50% decrease and 100% decreasein tariff rates).Findings: This study's resultsindicate that with the decrease of bilateral tariffs, the total CO2 emissions in Iran are increasing and by increasing commercial releasedegree, the volume of CO2 emissions increases and the total CO2 emissions in Eurasia have a decreasing trend and by increasing commercial releasedegree, the volume of CO2 emissions reduces. The results of this researchrelated to the economic welfare and production indicate that with the decrease of trade tariffs, welfare and production in Iran has an increasing trend and also welfare and production in the Eurasian Economic Union indicate an increasing and decreasing trend, respectively. The trend of the impact of technique (technology) in Iran is descending and in the Eurasian Economic Union is ascending, the impact of the technique shows a change in production technology, especially the shift towards clean technology. By commercial release, the impact of technology in Iran has resulted in an increase in environmental degradation, and in the Eurasian Economic Union, it decreases environmental degradation, proposing that the Eurasian Economic Union is moving towards clean technology and clean technologies have not been applied in Iran, and one of the reasons could be in terms of the lack of strict environmental laws in Iran.Discussion and conclusion: It is recommended that along with decreasing trade tariffs and using other provisions related to the agreement, applying tougher environmental laws as well as applying clean technologies and the transfer of this kind of technology to the country must be on the agenda.

Versus, returning to infill development principle and revitalization of lost urban spaces by creating attractiveness in historical contexts could be a stimulus for development of these areas. In this regard, implementation of urban catalyst projects in urban historical contexts is inevitable. This applied research seeks to explain and prioritize lay outing criteria of urban catalyst project in historical contexts. For this purpose, historical context of region 12 of Tehran despite of its valuable historical potential was selected in the center of old city of Tehran.Material and Methodology: This research is descriptive-analytical and uses Fuzzy Network Analysis (FANP) method to prioritize criteria. Thus, after studying the theoretical fundamental of research by documentary-library method, appropriate criteria for lay outing urban catalyst project were weighted by factor analysis method and entered in the Super Decisions software for evaluation.Findings: findings show that pedestrian priority, job creation and capital attraction are the most important criterion among the criteria for lay outing urban catalyst projects in the historical context of region 12 of Tehran. Also, the least importance was given to improving public transportation, reviving cultural and historical heritage and environmental quality criteria.Discussion and Conclusion: It could be concluded that facilitating pedestrian movement and creating employment play a significant role in lay outing urban catalyst project in historical context. Unlike popular belief that revitalization of cultural and historical heritage is the most important factor in stimulating the historical area, this criterion was ranked among the least important criteria.

Noise pollution may cause sleep disturbance, stress, loss of productivity in schools, offices, etc; This fact necessitates the need for considering social costs of noise pollution more carefully in urban areas. In this paper a model for evaluating monetary equivalent of noise pollution social costs in implementation of urban infrastructures has been proposed; General approach in this model is based on determining maximum allowable noise pollution in the affected area as well as determining intensity of the noise generated from operations in the adjacent receptors; Difference between the “existing” and “maximum allowable” noise levels is considered as part of the social costs of the project; Some methods for evaluating monetary equivalent of this social cost has been proposed in this paper; if the estimated value was large, some mitigation measures shall be taken to reduce the social costs of noise pollution; A number of these measures are also reviewed in the final part of the paper. In the end, suggested model has been utilized for quantification of noise pollution social costs in a small pilot area of Tehran where a sewage network has been implemented. Manuscript profile -

Since investors are usually exposed to different risks and due to the importance of risk in selecting projects, it has always been focused on the optimization of project selection and optimization techniques to reduce risks. The main risks associated with investment projects are divided into market and political risk groups, which can lead to decrease in productivity and increased cost in a capital project .Market risk consists of four risk factors: commercial risk, project progress risk, vector gain risk and construction risk. The aim of this paper is evaluation and ranking of market risks in selecting different types of capital projects based on mathematical programming model with DEA / AHP combined technique so that according to the relative weights, the overall impact of market risk on project prioritization is determined. After the implementation of the proposed algorithm, the risk of advancing the first priority, risk of construction / completion of second priority, risk taking and commercial risk were placed third and fourth priority so that investors can identify and reduce their effects in projects.

Therefore, such studies should be carried out based on forecasting. To obtain reliable results in these situations, risk analyses methods under uncertainty are used. One of these uncertainty methods is to employ models to be simulated. In these models, some factors as random variables will be studied for the future. Future prediction of each random variable is assessed considering a probability distribution function. The aim of this research work is economic evaluation of Koohzar gold mine in Torbate-Heydariyeh, Iran for a seven years period using simulation and its application in risk and decision management, and estimating its NPV by applying General Regression Neural Network artificial intelligence method. For this purpose, first, probability distributions of the variables were obtained using information from the variables in previous years. Next, distribution functions of uncertain variables are replaced in appropriate cells of discounted cash flow (DCF) table. Then, random sampling was taken from the probability distributions of uncertain variables as an input of cash flow analysis. In the next stage, based on the simulation technique, probability distribution for NPV variations was obtained as the output in the form of graphs and a function. Considering the output, all of the NPV variations can be forecasted. Then, a general regression neural network was designed using simulated results for NPV prediction using input variables. The results show high reliable capability of general regression neural network in prediction of NPV. Manuscript profile -

So the economy and technologies largely depends on consistent renewable source with environmental criteria of biomass and actually biogas. Biogas technology is associated with certain limitations in addition to the many advantages. So that energy production is a difficult task without having stopping elements in which the alternative concepts is necessary to ensure sustainable development with accessible technologies. Further advances in technology led to renewed and deeper interest in biogas production, while it has great effects in reducing major economic problems in the world. The current review addresses the limiting factors and evaluation of recent technological advances associated with various aspects of biogas production such as the use of sustainable feedstocks, microbial and enzyme dynamics, optimization parameter and dissociation process to enhance this technology. Enzymatic bioassay and efficient microbial identification enables the energy of anaerobic digestion to be significantly enhanced. Therefore, optimization of different parameters to accelerate biogas production during anaerobic digestion has been preferred to pre- and post-anaerobic digestion. In spite of the development of multi-step digestion schemes in order to succeed in the separation process, further research is needed to achieve better system performance. Manuscript profile -

Criticism of lack of an appropriate social status proper to one's knowledge and art, nostalgia for poverty, lack of freedom of speech and action to express scientific and philosophical views, ignorance of citizens, etc., whose speech is constantly accompanied by projections such as attributing difficulties to the sky, rooted in Zarwani culture and is referred to as Destiny, implying the the will of God Almighty. Almost nobody admires the corruption, hypocrisy and coercion that dominates these poets’ social milieu. Therefore, occasionally the rationalists fail to grasp order and discipline in the universe. Some wise people have examined the issue through the lens of wisdom and philosophy, and some from the perspective of religion and mysticism. It is a pity that the role of men of power and statesmen is less well-addressed regarding these shortcomings. Some have called it the religion of the sea and others have labelled it as the law of whirlwind.

The field of artistic education has been forgotten and neglected, despite the tremendous impact it can have on morale and, consequently, on the learning of learners and even their educators.This research project is the "combined" type (simultaneous test). The study population included two independent groups of curriculum and education specialists (in the qualitative section) as well as primary school teachers (in the quantitative section). The sample size includes 12 curriculum and education specialists and 120 primary school teachers .The sampling method in the first part (qualitative) is theoretical and purposeful method and its tools include semi-constructed and unstructured interview and in the second part (quantitative) it is "purposeful and preferable" and the research tool includes a 30 questions researcher-made questionnaire. Quantitative data analysis involves the Wilcoxon single-sample and Friedman tests to rank the Barriers to the implementation of the Fundamental Evolution Document based on the components of the Fullen model. Qualitative data analysis was also performed using the seven-step )Colaizzi, 1987) method. The results of the study confirm the gap between the designers of the Evolution Document and its implementers in schools, which, in addition to other existing administrative barriers,contributes to the inefficiency of the Fundamental Evolution Document in the implementation phase.

The aim of this study is to decline the costs and loss of opportunities, using a model that can effectively reduce the error of expert. This study was performed in the Ghourchay Ramian basin. Firstly, distinct scenarios and conceptual and tree model were created for biological and mechanical measures (masonry corrective dams). Then the constraints and vector maps entered into the SMCE in ILWIS®3.7. Constraints (slope, land use, soil and streams) with Boolean method and factors (slope, height, soil, soil erosion, land use and proximity to road, village, fault, rock sources and landslide) with Fuzzy method (benefit, cost and compound methods) have been standardized. Then weighting of factors performed using the results of questionnaires and expert opinions with procedures as ranking, pairwise comparisons and direct method. Validity and reliability of the questionnaire, was controlled. Results showed that four ranking, which was specified in priority map, in biological plans, places with first priority allocated 0.73 to 0.97 scores and over 3 km of waterways and in dam and concrete plans, 0.65 to 0.86 and an area of 2470 hectares, respectively. The model type is logical and uses logical and optimization principles not experimental principles. So there was no try to test it with the previous schemes were implemented. Projects that many errors because lack of the possibility of combining several criteria and GIS advanced techniques. Finally, it was suggested that due to the high performance of this model for evaluating watershed management projects and prediction of projects for implementation, this model will be used in the same watersheds in the country.

In our current study, we adopt a contextual and inspiring approach and employ the "phronetic" research method. We focus on the extensive body of works by one of the foremost theorists in the field of mega-project planning , who has produced different and innovative insights in recent years. Our objective is to understand and explore the relationship between city and regional development, prosperity, and infrastructure mega- project. Referring to Bent Flyvbjerg's theory , researches and works regarding infrastructural mega-projects and their characteristics, we aim to shed light on the realities and some dark sides of these projects. Mega-projects typically consume a significant portion of budgets and public resources and are often touted for their anticipated benefits and advantages prior to construction. However, our study reveals that only a small fraction of these projected benefits are realized. In some cases, these projects even yield outcomes contradictory to their original goals. Nonetheless, the persistent desire of many political leaders and planners to pursue such projects can be interpreted from various political, economic and even technical perspectives. In the context of Iranian planning, where these dynamics are particularly pertinent, understanding the true nature of mega-projects becomes essential. This awareness can serve as a foundation for reevaluating the approach to prioritizing and undertaking such projects at both the city, regional and national levels. Manuscript profile -

117 - Assuring Sustainable Economic Benefit for Farmers by Using Ground Water in Semi-Arid, Hard Rock Areas in India & the Role of UNESCO-IUGS-IGCP Project 523
Shrikant Daji LimayeOut of about 1.2 billion people in India, 68% people live on agriculture as their main occupation. Ground water is therefore an important resource which provides over 70% of rural drinking water supply and about 50% of water used for irrigation. Rains in Monsoon season MoreOut of about 1.2 billion people in India, 68% people live on agriculture as their main occupation. Ground water is therefore an important resource which provides over 70% of rural drinking water supply and about 50% of water used for irrigation. Rains in Monsoon season from June to September, provide the main source of water but they last only for four months and the rest of the year is dry in most of the hard rock region. About 67% of India is occupied by hard rock terrain and about 30% of the hard rock area falls within semi-arid, drought-prone zone receiving less than 500 mm rainfall per year. In semi-arid, hard rock terrain in India and in many other low-income countries, the surface water resources are scarce and polluted. Ground water occurs in this area in the shallow weathered zone up to about 15 meters depth and in the deeper fractures and fissures up to about 100 m depth. Bore wells reaching up to 60 to 100 meters depth, installed with hand-pumps, are very common for providing safe drinking water supply to villages. This causes a positive improvement in the health of villagers and an economic advantage by reducing the number of working days lost due to illness. Agricultural production in these semi-arid areas is just marginal because the rain-fed crops suffer from the vagaries of Monsoon rains. The average farm-size per family of 5 persons is about 2 Ha. There are 3 to 5 drought years within a span of 10 years, which leave the dry-land farmer in perpetual poverty. In the past 3 years, over 4,200 farmers have committed suicide due to continued crop failures. Ground water, therefore, forms a very important and reliable resource which, if available in a farmer’s plot of land and if utilized prudently for irrigation by digging or drilling a well, could transform the farmers lifestyle. Even if the farmers are able to save one rainy season (Monsoon) crop through protective irrigation from dug well, and if possible take winter and summer crops on small plots, they would stabilize in the rural scenario. Otherwise, the farmers would migrate to nearby cities and stay in slums. Many cities in India and other low-income countries are suffering from an ever-increasing flux of rural population thereby chocking and polluting the urban environment and putting stress on urban infrastructure. Ground water development for irrigation is the lifeline for rural economy. However, in many watersheds in semi-arid, hard rock areas, the pumping of ground water is increasing and in some watersheds it is more than the recharge available from rainfall. In these over-exploited watersheds, the yields from the wells are not sustainable. Still, farmers in hard-rock area of peninsular India are taking all risks to develop ground water for irrigational and domestic supply because of the economics underlying its use. This paper discusses the economics of ground water use and gives guidelines for sustainable development, such as availability of soft loans to farmers, insurance for failed wells and people’s participation in augmentation of recharge to ground water. Some of these guidelines have been included on the website www.igcp-grownet.org of UNESCO-IUGS-IGCP Project GROWNET, (Ground Water Network for Best Practices in Ground Water Management in Low-Income Countries) for which the Author of this paper is the Project Leader. Reverse migration from cities to villages is possible only if sustainable ground water development is done in these semi-arid areas, through watershed protection and recharge augmentation activities, as advocated by the GROWNET project.

Different risk assessment methods are used to manage these risks, especially in Engineering Procurement Construction (EPC) projects. On the other hand, considering the number and variety of risks in Engineering Procurement Construction (EPC) projects, determining their weight and ranking is of particular importance. This research is applied in purpose and is conducted in the head office of one of the petrochemical companies and two groups consist of experts of contract education and contracting unit (project management contracts) to collect the selected information that answered the questionnaires. In this study, the identified risks were evaluated and rated using the failure modes and effects analysis (FMEA) technique, and the critical risks were weighted and ranked using Analytical Network Process (ANP) and superconducting software. According to the results of the study, contract estimation risks were the least important and engineering sector risks were the most important. The results also showed that the risks of logistics sector, risks in contract estimation (values and costs), financial sector risks and finally engineering (design) risks are more important respectively.

Implementation of these projects requires spending time, cost and other resources. Lack of proper contract arrangement and unfair distribution of responsibilities and authorities have led to many challenges among projects’ employers and contractors. On one hand, civil projects confront with threats and opportunities regarding the key elements of project like time, cost and quality in order to achieve the specified goals. The roots of most threats ad chances can be find in a set of uncertainty conditions that regarding to varying and unstable conditions of country, they have great effect on the process of project execution, and the probable conditions shall be recognized and predicted. Types of civil project contracts were conducted by multi-indicator decision-making techniques and approach of scenario planning. At first, types of contracts being able to conclude in organization were recognized. Then, the options’ rating indicators was specified by studying the organization’s strategy document. Moreover, to determine the uncertainty, by reviewing the literature we identified the effective factors on indicators and they were classified into under control and out of control factors. Uncertainties were specified through out of control factors, and scenarios were developed. Ultimately, by Max-Min method, strategic options were rated according to 4factor method, E.P.C, design and construction method, P.E, 3 factorial method and turning key method, respectively.

In this research the sample selected for participation in the Delphi group, experts and managers and experts in industry and international trade, managers of companies involved in exploiting industrial projects in Zanjan province, 23 respondents as Delphi group responded to the research questionnaires. The result showed that the first effective factor resulting from the sanctions in delaying the use of industrial designs is the increase in the cost of finished products. Also, the increase of the exchange rate in Iran from production to import and export. Also, the limitation of the expansion of LC is another factor affecting the cost products of finished products. Also, the limitation factor in currency transfer is very important in delaying the operation of industrial projects, since foreign purchases and import of industrial goods require currency exchange, and the lack of transfer of currency to the country causes delays in the exploitation of industrial designs Manuscript profile -

Unf MoreTime-cost-quality trade-off project scheduling problem is one of the most important and practical problems in project management discipline. Project Managers interest in making decisions to accomplish the project with minimum cost, minimum time, and maximum quality. Unfortunately, in real life problems, the estimation of time, cost, and quality may be mixed with uncertainty. These parameters may be far from their estimated values. So, considering uncertain parameters in time-cost-quality project scheduling is essential. In this paper, a probabilistic version of time-cost-quality trade –off problem is proposed. Some parameters of the proposed model are assumed to be probabilistic. The probabilistic nature of the proposed model is handled using stochastic chance constraint programming. The multi-objective nature of the problem is handled using goal programming. Finally, the stochastic chance constraint goal programming is proposed. The deterministic equivalence of proposed stochastic model is presented. A numerical example is analyzed using GAMS software and results are investigated. Manuscript profile -

Considering all organizational aspects in obtaining projects is the most key point in the success of project-oriented organizations. For this reason, choosing a portfolio of projects in a way that can meet the goals and strategy of the organization, in addition to considering the organizational limitations, is very vital. For this reason, in this research, while emphasizing the implementation of the portfolio management process in organizations, a two-stage model is presented for evaluating and prioritizing projects to form an optimal portfolio. By examining the life cycle of projects, first, 12 influential indicators in the evaluation of projects are extracted with the help of previous research, and after the confirmation of 8 important indicators by experts, they are analyzed with the help of fuzzyDematel technique, and the weight of each indicator is determined. In the next step, the proposed projects are evaluated and prioritized using the fuzzy TOPSIS technique. Finally, taking into account the capabilities, assets and limitations of the organization, the optimal portfolio of projects is formed and approved by the decision makers. By implementing the above model in a construction company active in public and private projects, it was found that the analysis of relationships between indicators helps a lot to choose the optimal portfolio and prepares the ground for achieving the set goals.

In a MoreThis paper aims to determine factors influencing on the buffer sizing based on Project Risks, which are usually subjective and qualitative. Because of the subjective feature, they can’t be calculated accurately and they are responsible for the project delays. In addition, because projects may enter a time of shortage, as well as inadequate resources, estimated time duration prolongs which in turn increases the project costs. On the other side, offering a conceptual model, this investigation aims to identify risks relationships and interactions. Fundamental and related risks were defined in the proposed model which is based on a conceptual model. The model also can be used to better buffer sizing and improve time duration and cost estimations. Interpretative Structural Modelling was used to develop the conceptual modeling and 27 experts in Oil and Gas Mega Projects were interviewed to gather the needed data to provide the model. Based on the conceptual model and simultaneous analysis, the problems caused by the complexity and low recognition of the technical issues of the project are the main factor that put managers and contractors in a situation to increase the level of buffers.

Also, it is used to increase resources performance and to utilize restrictions of project system. To secure project against probable disturbances time buffers were installed in different areas based on this approach. Thus, tensions of uncritical activities were kept to be transferred to critical chain and tensions of critical chain activities were prevented as well to be transmitted to project delivery time. In the present paper, a method to determine buffers size in the domain of critical chain was presented. The method fortified with such main characteristics as applying experts’ ideas throughout the work steps, as well as the simple implementing process. Even though the concepts proposed in this method are close to “Pert” method, the distribution function of activities time probability in the method was obtained according to experts’ ideas. Finally, the critical chain was conducted for designing, constructing, and installing of a steel structure in Suliran Company to assess the suggested method. Buffers size were estimated using two recognized methods in pieces of literature, Cut and Paste (C&P) method, Root Square Error (RSE) method, and the proposed method. Comparing with two mentioned methods, the presented method, as obtained results display, generates buffers with more protection against project's probable delays. Manuscript profile -

Since reducing delay in industrial projects is important, in this research, we decided to investigate the main factors of the delay in the petrochemical industry as one of the profitable industries and job creation field. The results indicate that such factors as the sanctions, reduction in the oil prices and the global economic downturn are among the most serious influential reasons. This problem especially is more reflected in workload fluctuations in the construction Industry. OPEC Members (Iran, Iraq, Kuwait, Saudi Arabia, Qatar, Venezuela, etc.) are exposed to these fluctuations and petrochemical constructions and their products are jobs creation factors considered as the important economic positions for these countries. The current study aims to investigate the factors causing a delay in the construction and commissioning of petrochemical projects. The most serious challenge these countries encounter in the development of this industry is considered from four perspectives: time, money, quality, and structure. Applying grounded theory method and by doing semi-structured interviews with a group of experts in petrochemical industry concepts obtained from extraction case studies and organized in the form of four hypotheses and presented in a conceptual network.

The very difficult nature of that issue is also another reason for the researchers to take much note of it. Therefore, there are especial techniques and methods to solve those issues. Also, project managers pay much attention to the stability of the time schedule as it is important for them. This paper is provided with a real project time schedule for a refinery by using stable time schedule. Particle swarm optimization algorithm is suggested to resolve the problem since the project time schedule has resources limitation including NP- Hard. In order to accesses the validation of the model, 4 issues with small scales has been selected and the results from the suggested algorithm was compared with the accurate result obtained from lingo software. These results indicate that the suggested algorithm is effective and convergent with the optimized result. Manuscript profile -

This tools and techniques specify a prioritized projects list that should be selected for final allocation. Usually, using financial approaches can’t create an optimal portfolio especially in projects that have more uncertainty, this approaches can make wrong results. In these cases, these financial approaches should be combined with other approaches (such as strategic approaches) in order to make a balanced portfolio that is aligned with organization’s strategies and increase profitability and strategic adaption of projects. Besides, various investments are evaluated and selected differently and classification of projects in different portfolio allows organizations to evaluate, prioritize and select similar projects in the same portfolio by using similar tools and techniques.

These companies had to consider many parameters like risks, resource constraints, time constraints and the expected project’s profit in their selections, to name a few. The importance of this topic leads to create several models to choose projects. Each model refers to special aspects of the problem. Therefore merging of this aim is necessary. This research tries to represent a combined approach to project selection. This approach determines economic, profitability and restrictions aspects of doing the project. Three methods of Delphi, dynamic ranking and Goal programming of this model. In the beginning part of this model, we use the Delphi method of calculation; Probability of technical success and strategic importance of each project. In the next step, we use earned weights by the first step and economic data of projects as dynamic rating inputs, at the end of this step economic weight will be given to each project, then this weights will be used as coefficients of Goal function at the third step. At this step Goal programming used to determine restrictions. By this model, the investor can consider economic, profitability and restrictions aspects of doing project easily and choose the best choice. At last foresaid combined approach is used to choose one of A or B Investing project as an example. To solve Goal model winQSB software is used. Manuscript profile -

The issue of quality increasing is a big challenge since the starting the project both for construction companies and buyers. Although no distinctive quality assessment studies have launched for these projects, there are some different assessments programs which can be applied to study the issue of quality for these mass construction. QFD is one of the best methods for assessing the quality which can cover both buyers and engineer's needs. This paper has applied two QFD strategic and operational methods. The former deals with the mass construction aspect and covers quality development process in management level of production. To do so, two levels are brought into consideration. Using the AHP and QFD, the first level analyzes the obtained information which identifies 16 criteria of building quality and three involving factors in building process. The factors can be identified as design, operator, and Department of Housing and Urban development determining their role in increasing the quality, as well as their relationship to increase the quality level. The second stage is to detect the compatibility level of ideal quality with the constructed buildings. The results show that three abovementioned factors have the even and equal role in Mehr mass construction project. Also, the project quality index (QPI) estimation for Sanandaj Mehr Mass Construction Project is about 53%. This method can be recommended for almost all construction projects. Manuscript profile -

The data sample involves research-intensive companies which engage in collaborative research on a regular basis. Over 100 different collaborations projects are analyzed through interviews with the responsible project managers and with senior technology officers. The interviewees provided both quantitative and qualitative information about the success and lack of success of the collaborations. Based on these data, seven best practices for managing collaborations have been defined which, when taken together, significantly contribute to the long-term success of the collaboration. These practices are: 1) select collaboration projects that complement company R&D; 2) select university researchers who understand specific industry goals and practices; 3) select project managers with strong boundary spanning capabilities; 4) promote longer collaboration timeframes; 5) provide appropriate internal support for project management; 6) conduct regular meetings at the company between university and industry researchers; 7) build awareness of the university project inside the company.

The main reasons of the occurring problems can be incorrect designing, the perplexity of technology, variety of expertise needed, plenty of activities and number of stakeholders engaged. For these reasons, the project is not usually completed in due time and in the amount of the predicted cost scope. Value engineering (VE) is a problem-solving method (PSM) based on the systematic job plan and creativity. VE aims at reviewing the project and identifying the opportunity of saving project cost and time. Regretfully, in the same cases, VE is not adjusted with needs, specifications, and limits of project construction and that cannot remove the problems. This paper can use concepts and techniques of total quality management (TQM) for developed VE structure and increase its effect on the construction project. To create a new model, first, VE, TQM, and problem of construction project were reviewed. Next, using other accomplished researchers in this field of study, development potentials of VE was identified. Finally, a new model was issued based on the studies. Manuscript profile -

Created in recent years by Eusuff and Lansey, SFLA algorithm works in a way that the frog groups search for food. The development of memetic algorithms for local search method is similar to the activities of a frog among subgroups. SFLA uses a combination of strategy and provides the ability to exchange messages in local search. Frog leaping algorithm combines the advantages of particle swarm optimization algorithm and memetic development (PSO). Since the resource-constrained project scheduling problem is the timing issue, scheduling issues in the construction sites and plants is highly considered. One of the main duties of the project scheduling and project management is to reduce the completion time. Because of the resource constraints and precedence relationships between activities, project scheduling problem is difficult. In this paper, the algorithm performance LeapFrog (SFLA) is applied to reduce the project scheduling problems with resource constraints. The findings prove the robust performance of the new meta-heuristic algorithm. Manuscript profile -

Increase in the number of vehicles causes violation detection, road congestion, accidents at different traffic situations, uneven illumination, lighting and weather conditions. To overcome this issue license plate number is recognized but due to variations in license plate layout, font size of characters, tilted number plates, weather conditions, dirt plate and motion blur license plate recognition becomes difficult. License plate recognition has two main tasks, one is to detect the license plate and the other is to identify the license plate characters. By using region of interest license plate is detected. For recognition first tilted images are corrected using affine transformation and to improve the quality of a low-resolution image super resolution CNN is employed and connected component analysis, horizontal and vertical projection profile area used for separating each individuals characters. Each individual character image is fed to the Convolutional Neural Network (CNN) for character extraction and for classification and the license plate is recognized using convolutional neural networks. The main aim of this paper is to recognize different plate layout with different conditions with minimum data set and less processing time with maximum efficiency. Manuscript profile -

One of the main challenges in this case is choosing the right approach to achieve these goals. The most common approaches in this case, are using the balance technique. In fact, using this technique can be the most optimal mode of project implementation activities that the lowest and highest quality at the lowest cost, time has obtained. In this paper, we tried to develop a goal-programming model to find suitable responses for managing the cost, time and quality of the project. In order to test this model, a case study was accomplished in the projects implemented at Company Machine Sazi Arak. Computational results show the applicability and usefulness of the proposed method. Manuscript profile -

The problem of corporate inefficiency is a global concern and the Iranian Water and Power Resources Development Company (IWPRDC) is no exception. A number of problems such as project delay, highproject cost, and low profitability are some cases of deficiency and have forced managers to pay meticulous and scrupulous attention to causes of such deficiencies and find effective alternatives to improve performance. One of the prominent factors is inappropriate structure. Before designing new suitable structure, the managers must identify the main factors that cause inefficiency and determine which of them affects structure. So, corporate diagnose and analysis is an important stage in restructuring project. This paper presents a research to cast light on diagnosing IWPRDC in Iran, tries to represent the collected data through a semantic network, and finally, shows a quantitative network analysis of corporate inefficiency causes.

Petrochemical Projects in Iran have faced a violent business environment as a result of the Sanctions, change in oil price, exchange rate, and input price of plants. Based on the contingency theory, in order to achieve better performance results in projects as contemporary organizations, it is necessary to consider Business Environment in formulation of project strategy. Therefore, the purpose of the current research was to present the typology of the project strategy based on Business Environment contingency variable influencing the Iranian petrochemical Projects. By reviewing literature we provide a conceptual model as our first-order construct. Using cases study research; we chose to employ qualitative method for improving the model. The case data of 10 projects was selected from the petrochemical Projects. Qualitative data analysis was used for data analysis. In addition to interview, multifaceted data collection including document investigating and questionnaire was also considered. Regard to selecting the Miles and Snow business strategies as baseline of the project strategy, project strategy typologies was plotted in a two-dimensional matrix in terms of fundamental/gradual environmental changes and internal/external project focus. These typologies were redefined for project level through interviews results. Finding suggests that Business Environment difference of projects caused different projects Strategies that required different entrepreneurial, engineering and administrative capabilities to manage projects.

Examining various sources, it was observed that although the EVM analytical model has introduced good indicators for measuring project progress, it is weak in estimating the final cost of the project and does not predict the process of cost change and project efficiency. On the other hand, nothing has been done so far to use system dynamics in EVM.Therefore, considering the capacity of system dynamics in modeling complex systems and setting parameters dynamically based on model variables, the main problem of modeling research is the value model obtained by simulating system dynamics. The dynamic hypothesis of the research was that there are dynamics between the main indicators of EVM. Identifying these dynamics and the way they affect each other can lead to estimating the process of changing costs and project efficiency by the end of the project.Through presenting the causal loop diagram and the stack flow diagram of the proposed model, the variables were determined and after simulation, the model was validated by performing various tests and different policy scenarios were presented.The comparison of the results of the research simulation model with the results of the EVM analytical model revealed that there is a slight difference between the results and the efficiency. The main contribution of the research is the creation of a simulation model based on system dynamics as the core of the simulation to estimate the trend and the final amount of efficiency and cost of the project, which can be part of a more comprehensive simulation model.This can be used to determine the impact of various project management functions on improving project efficiency, which is the main suggestion for further research.

Thus, the purpose of the current applied descriptive correlational survey was to examine the extent to which components of risk failure structure can impact the goals of municipal construction projects including citizen satisfaction, cost, time, quality, range and safety using Bayesian Belief Network (BBN). The purposeful research sample comprised 45 managers, deputies, relevant officials and experts in Isfahan municipality who were consulted to identify the project risk dimensions during 2016 and 2018. A questionnaire was employed to collect the research data which were further analyzed using the project risk structure breakdown to classify and identify risks and matrices. Partial Least Squares Method of Structural Equation Modelling (SEM) was employed to validate the questionnaire data. The simultaneous impact of risk dimensions on project goals was investigated using probable cause and effect modeling based on Bayesian Belief Model. The findings verified the significant positive impact of project risk components on the project objectives. The innovative characteristic of the current study was the integration of SEM and Bayesian BBN and application of error state analysis technique and risk effects in risk failure structure which can establish certainty concerning the analysis of risk dimensions and their relationship with precision of priorities in risk management process.

When processes become old and inefficient and can't deliver results that they were originally designed, for they must be redesigned or replaced. Business Process Reengineering (BPR) is a process-based management tool that can deliver, redesign or replace inefficient processes, as required. Despite high effectiveness of reengineering, the implementations of these projects often fail. The purpose of this study was to investigate the effect of components of BPR projects implementation on the success of these projects. The developed model included business process reengineering project success, as the dependent variable and top management support, organizational culture, education, communication, ICT infrastructure and BPR project management as the independent variables. Research population included individuals who involved in the reengineering projects in organizations that have recently implemented these projects. By using manual and electronic questionnaires, the data of 150 persons involved in BPR projects were collected. To analyze the data, structural equation modeling was performed, using the R software. Because these projects are in their early stage of implementation in Iran, only the effect of ICT infrastructure and BPR project management was approved. Manuscript profile -

This public organ as the most influential one has shouldered a wide range of duties and services and will undergo more responsibilities within the prospect of 20 years of civil development and the fourth development plan of the country. One of the most common dilemmas of the municipalities is the delay in execution and accomplishment of the projects. If any of the projects faces delay, not only will the national investments be wasted, but also they will lose their technical and economical legitimacy. So, a field analysis was carried out in Zone One of Tabriz municipality in order to identify the influential factors on the delays. At first, in order to analyze these questions, various resources were studied and then the influential factors were classified in four groups of employer, counsellor, contractor and the environmental factors. Then a questionnaire was compiled. Next, having studied the validity and reliability of the questionnaire, we distributed it among the statistical population and the data were collected. Finally, by using the T-test scores, the influential factors were identified. The influence rate of each factor was identified according to the Friedman test. As a result, with the help of the data, practical solutions were introduced to stop the delays. Manuscript profile -

Activity durations are considered to be deterministic in critical path method (CPM). Since it is impossible to predict future events in a deterministic manner, project evaluation and review technique (PERT) is introduced which studies project with probabilistic activity durations. In this technique, large variance of path durations can influence the calculation accuracy, in which case the simulation technique is an appropriate method. In this paper, a sample arrow network is chosen, and a time distribution is fitted for each activity with Input Analyzer Software using some historical data. Mean square error, chi-square and Kolmogorov-Smirnov (K-S) tests are used as three measures to evaluate the goodness-of-fit. In the next stage, a computer model is built for the network in Arena 7.0 software. This model is run 120 times and based on these replications, the minimum required sample size for (1-α) Í100% confidence interval is specified. Finally, a confidence interval is computed for duration of each network path and based on this; the time completion of project is estimated. Manuscript profile -

In this regard, the current theories will be classified into six approaches: concept and meaning, aesthetic, social-cultural, nature and ecology, designing, form, function, planning and the process of designing and they will be analyzed accordingly. It should be noted that this study will be carried out at two levels; at the qualitative method level which is based on the grounded theory that analyzes theories by encoding concepts. At the second level, a comparative approach is used in which the extracted criteria from level one will be evaluated in the contemporary landscape architecture of Iran. The results suggest that there are some drawbacks regarding the aforementioned categories in the professional architecture projects of landscape in the country, in a way that in issues such as connecting landscape with architecture, perceiving landscape, flexibility and planning landscape no attempt has been ever made, but the cases of patterns, symbols, tradition, order and geometry are going to be investigated favorably. Therefore, by making effort to compensate for the mentioned shortcomings we can have a considerable development in all of the cited dimensions. Manuscript profile -

This trend was forgotten following industrial revolution and domination of vehicles in cities. The metropolitan of Tabriz is not as exception from this rule and domination of driving spaces has limited presence of citizens in urban spaces where negligence of pedestrians’ demands is an important dilemma. The objective of the present study is to compare the walk ways of Tarbiat and Valiasr in terms of walking centeredness components. This study is conducted using descriptive analytic method and is an applied research where data and documental information were collected applying a survey method. Sampling in Tarbiat and Valiasr walk ways was performed using Cochran formula using random sampling in 2015. This study used elite and specialist ideas to determine the validity and also KMO test was used to test the reliability of the study which was higher than 0.50 in both Tarbiat and Valiasr walk ways. Finally, the obtained data were analyzed using factor analysis. The results of this study indicated that 5 factors of “services accessibility”, “security situation”, “facilities of walk way”, “environmental utility” and “attractiveness and aesthetics of walk way” are the most effective factors in defining walking centeredness in these walk ways. The results also indicated that service accessibility with 25.14% and security situation with 20.48% are at desirable level in Tarbiat walk way, and facilities of walkway with 25.26% and environmental utility with 21.40% are at desirable level in Valiasr walkway from the perspectives of the participants.

Urban regeneration and catalyst project drives have different dimensions from the physical ones on which this study has focused. After reviewing the characteristics of urban catalyst projects, the physical indices were identified. Then, the physical changes in the residential environment of the Limjir neighborhood located in the 11th district of Isfahan before and after the construction of Limjir street as a catalyst project during the years 2009 to 2016, were evaluated and analyzed using a variety of methods, library, and field measurement methods. Then, using the Analytic Hierarchy Process model (AHP) weighting, scoring, and calculation of the integration index in two conditions before and after implementation of the catalyst project is addressed. A comparison of index values in two periods 2009 and 2016 shows that the construction of Limjir Street causes the development and improvement of the physical status of the Limjir neighborhood. Also, the calculation and comparison of the integration index show that the physical condition of the Limjir neighborhood has improved by 0.308 in comparison to the situation before the construction of the catalyst project in 1388. Factors such as improving access to Limjir street, investment in the housing sector and extensive construction, increased service, and mixing of land uses have had the highest share in creating positive changes in the Limjir neighborhood.

The extensive experience gained over decades through diverse policies, including government programs and urban-rural development projects in Iran, emphasizes its central role. This study aims to propose an effective policy for enhancing housing quality. The theoretical segment synthesizes principles from participatory planning, sustainable development, and the boom-axis. Employing a qualitative approach, the research utilizes the Grounded Theory (GRANDAD THEORY) for data collection and analysis. Fifteen in-depth interviews with knowledgeable elites on the subject constitute the primary data source, conducted through exploratory and descriptive phases. Subsequent to each interview, coding of the data ensued, employing the continuous comparison method across open, axial, and selective coding stages. The analysis revealed an optimal model for housing quality improvement with eight key components: effective policy design mechanisms, development plans, financial frameworks, institutional-legal structures, transparent regulatory mechanisms, educational initiatives targeting academic and popular elites, cultural mechanisms, and mechanisms for restructuring the housing framework. The establishment of a model to enhance housing quality is contingent upon the dynamic interaction with these identified mechanisms. Manuscript profile -

Considering the past of historical identity of different period, it has a new identity consistent with conditions of today’s life on its agenda. Accordingly, urban regeneration becomes a comprehensive concept, a concept that considers improvement and rehabilitation of old textures in all economic, physical, social, and cultural dimensions. This research is a comparative study of regeneration of Khayam texture of Tehran, and Liverpool 1 in the UK, because both samples are located in central texture of the city, and their surrounding textures has identity-related values. Regeneration plan for Liverpool 1 project (2008) was recognized as the Europe’s best regeneration project, and Khayam block redevelopment project (Tehran) is also the largest recreation plan conducted by Tehran municipality after Islamic Revolution. This comparison aims to study objectives and measures in the two plan, the reasons behind the success of Liverpool 1, non-realization of predetermined objectives in regeneration of Khayam, and finally, provision of solutions for realization of predetermined objective of Khayam texture. The result is that adoption of short term and temporal policies, with consistent and prearranged planning, and lack of public participation from the beginning to the end, and failure to consider historical identity and position of Khayam texture resulted in failure of Khayam regeneration. Descriptive-analytical and comparative research method was used. Data collection was conducted by documentary, library and field observation method. Manuscript profile -

For this purpose, the system of simultaneous equations was used based on Iranian Registry data from 1976 to 1978. Estimated coefficients for the effect of financing through public-private partnerships and government funding on development were tested. The results showed that public-private partnership financing was about four times more likely to affect development than government funding. This difference is not rejected at the 98% level. It is proposed to increase the share of financing through public-private partnerships rather than through government funding to further the development goals.This move, in addition to freeing up government funding for other development goals, allows for increased private sector participation.

This theory introduces a systematic method for stability analysis of dynamic systems, under changes in the system parameters. In fact, a parameter is constantly changed in each step, using MATLAB and/or AUTO software, and system eigenvalues are monitored simultaneously. Considering how the eigenvalues approach the system’s imaginary axis on S plain in accordance with the changes in the targeted parameter, the occurred saddle-node and/or Hopf bifurcation of the system is extracted. In this paper, at first, electric arc furnace is modeled by the differential-algebraic equations and then based on the projection method, two-dimensional center manifold at the Hopf bifurcation happens in the electric arc furnace system is achieved analytically. Projection method is discussed in the bifurcation theory and is presented totally in this paper. Finally, the results are compared by the computer simulations. Manuscript profile -

The study has tried to reveal in detail how the social rights and freedoms, ethics, social norms, and values of the individual will be affected and where the borders will begin and end in the event of the potential risks that HGP carries. Discussions have been made on the problem that the individual can be instrumentalized and turned into a commodity as a result of genetic interventions, and unfortunately, it has been determined that genetic interventions are in a structure that can lead to an intervention in the fundamental rights and freedoms of the individual. This study aims to show the usage areas of the human genome project and to examine the results of this project in terms of the ethical consequences of the techniques and applications used.

Althou MoreAdopting risk management is a must, inevitable in all construction projects. Risk management is very important in retrofitting of the projects. Strengthening the reinforced concrete beams with respect to their type and how they are made is assessed in this study. Although both of the near-surface mounted (NSM) and externally bonded reinforcement (EBR) methods have advantages and disadvantages and it depends on the reinforced member and the project conditions, but in general, the NSM method outperforms the EBR while somehow (EBR) is adopted more. A researcher-designed questionnaire consists of ten restrictive factors regarding NSM implementation. The responding persons consist of skilled experts with at least five years of experience in this field. The execution of risk management in NSM, obstacles on the way of implementation, and the effect of risk management on the functionality of these factors are of concern here. The obtained data is assessed through statistical tests. The factors of more execution time, lack of experts, high volume, low knowledge on the client, uninformed employers, consultants and contractors about the existence of this method, complexities in the calculation, big calculating mass, concrete cover 5-7 cm, FRP rebar needed in NSM, high implementation cost and high FRP implementation cost are considered as the restrictive factors affecting NSM implementation. The initial assumption that the ten factors were restrictive as to NSM implementation led to proving that the factor of lack of information about this method within the client, contractor, and consultant was the most effective as a restriction. This proof was obtained through the statistical tests conducted on the assumptions. Manuscript profile -

In fact, they are an integral part of development programs in different countries. In this regard, rural improvement plans aimed at strengthening the social, economic and physical foundations of the villages of Iran at rural districts and villages level at penetration zone centered by rural district do classification of social and infrastructure services at rural district level. Finally, by preparing reconstruction plansof the central village, a model for the physical development of the villages at penetration zone with different instructions would be provide. Now, after more than two decades since the beginning of implementation of rural improvement and guiding plans in rural areas of the country and spending huge costs in the various stages of its preparation and implementation, we are witness many works in different fields, such as the transformation in village context, changes in the pattern of housing construction, inconsistency in the village passageways network, facilitating the commuting of the villagers, and so on. The objective of this study was to analyze the effects of the implementation of reconstruction plans in Workaneh village from the villagers' point of view. The research was descriptive analytical method which is for collecting data, field study and documentary methods were utilized. Accordingly, based on the population size (219 households), the sample size of studied households was 214 households through all calculation. To analyze the reliability of the research tool, the questionnaires were given to 30 heads of households, the results were examined and Cronbach alpha was calculated. The obtained result was 0.94% which was rather an acceptable figure. The findings indicated that rural improvement plans had a positive and significant relationship at level 99% in five indexes applied in this study including housing, health, land use, passageways network, economic and social indexes. However, there was no significant effect between the economic status of households and the effect of the mentioned indexes. Also, the results of the Chi-square test showed that there was a positive and significant relationship between the type of main occupation and the resulting variables from rural improvement plans, i.e., housing, health, land use, passageways network, economic and social indexes at level more than 99%.

These types of projects, which are defined on a neighborhood scale and in proportion to the tolerable capacities of local systems, are based on all-round participation and social capital.Objectives: Estimating the consequences of reviving the Zanjan match factory and changing its use to a museum, in the satisfaction of the citizensMethodology: In this research, which has been prepared by descriptive-analytical and survey method, the indicators in the form of three dimensions of "residential", "activity" and "physical" and seven factors have been determined as the theoretical basis of the research. The statistical population of the study is the citizens of Zanjan over 18 years of age, 384 of whom have been selected according to Cochran's formula in three groups: "merchants and residents of Kochmeshki neighborhood", "operating organizations and institutions" and "museum visitors". Data analysis was performed using one-sample T-Test and satisfaction-significance model.Geographical Context: The study scope of this research is the city of Zanjan, where the Zanjan matchmaking factory revival project has been carried out as a micro-scale development catalyst project with minimal intervention in its central context.Results: Surveys show poor and average satisfaction of the target groups of "general texture status", "economic status" and "residential status" and very poor satisfaction with the "activity status" factor. This is while the importance of the factor of "general condition of the tissue" was more than other factors and the factor of the factor of "economic status" was less than the others. In this project, only the factor of "environmental and physical condition of housing" has been able to satisfy the target groups in proportion to the importance they attach to it, and the other factors have distanced themselves from their importance. Findings also show that except for the factor of "activity status" which is in low priority and "general texture status" and "residential status" which need further strengthening and upgrading, other factors proposed in this project are in a favorable condition that their stabilization recommended.Conclusion: The results of this research show that audience satisfaction and the importance of evaluation indicators have a statistically significant gap. This gap shows the failure of the planners in providing the optimal level of indicators of the studied project which are important and priority for their audience. Manuscript profile -

Thus, in line with MoreIn the modern world of business which is based on competing and delivering the best performance to achieve the organizational goals. The commercial growth development and natural resources usage can’t be gained without considering their effects. Thus, in line with the sustainable development principles, project-oriented organizations aim to be successful in project management, gain the profit and satisfy the customers. Profitability and be successful in the project performance are based on creating value for the customers, adapting to market changes, environmental constraints and to be responsive to the customers’ needs. Therefore, to successful implementation of the project management in parallel with the sustainability principles will be possible by creating the agility parameters. For this purpose, the current study, has provided an approach to identify and rank the agility factors in project-oriented organizations, based on project management critical success factors and sustainability factors, applying quality function deployment. To this end, firstly, project management critical success factors and then, agility and sustainability factors in project-oriented organizations, have been identified. Thereafter, the importance of the project management critical success factors and agility factors have been evaluated from the Isfahan Municipality’s experts’ and academia experts’ viewpoints. Afterward, Agility factors’ weights in project-oriented organizations have been calculated based on the project management critical success factors using quality fuction deployment. Finally, on the basis of the calculated weights, agility factors in project oriented organizations have been ranked. Manuscript profile -

T MoreMegaproject is a term used to distinguish strategic projects from normal projects. The super project requires the allocation of many resources and has transformative consequences. Much research has been done to identify the success and failure factors of megaprojects. This research aims to analyze the knowledge structure of the success and failure factors of megaprojects. Research is practical in terms of purpose. The statistical population of the indexed content research related to the success and failure factors of megaprojects in science websites, the judgmental sampling method, and the sample size are 3728. The method of research data analysis includes the analysis of the structure of the context and the analysis of the content structure. Contextual structure analysis includes the steps of cataloging, sorting, illustrating, and contextual data analysis, and content structure analysis includes two steps of data extraction and coding. The analysis of the texture structure confirms the upward trend of indexing, the dominant flow of introducing a country as a megaproject platform, and the greater contribution of indexing to the field of project management. Analysis of the content structure has identified 277 codes, 177 concepts, 101 subcategories, 69 categories, and 9 dimensions. These dimensions include the success and failure of megaprojects, context, domain, super project teams, super project life cycle, investment, environment, involved parties, and social factors. The theoretical dispersion in the selection of vocabulary indicates the need for convergence in the selection of vocabulary and the necessity of identifying theoretical frameworks from the indexed content related to the success and failure of megaprojects.

The huge volume of semi-finished development projects is one of the realities of public sector management in the country at present. MPs consider the approval of the public-private partnership bill as the solution to the semi-finished projects. This qualitative research tries to answer two questions by analyzing the opinions of experts: first: can all semi-finished projects be ceded and second: What are the ways to economize plans for assignment? The text of the interviews has been opened by the coding software. The results of the analysis are that there is no general solution for all projects and in each case according to the background conditions (classification of unfinished projects, the possibility of their economization, etc.), causal conditions (control of project approval), conditions Intervention (use of the capacities of transfer laws, entry of the privatization organization into this issue, etc.), strategies (development of legal prerequisites, preparation of regulations, etc.) and outcome (motivation for project managers by creating a return method Resources saved, etc.) are necessary.

Due to the lack of internal production, high imports and high consumption of this material in the country, the construction of its production unit seems necessary. However, making a confident decision about construction and financial investment requires a comprehensive economic analysis. In this study, the economic evaluation of azodicarbonamide production was performed and economic indicators were investigated. Capital expense (CAPEX), operating expense (OPEX) and total expense of the project with a capacity of 1000 tons per year were estimated equal to 230350, 117040 and 347390 million Rials, respectively. The analysis of the economic indicators of the project including the internal rate of return (IRR) of 38%, net present value of (NPV) 126701 million rials, rate of return of 31% and payback period of 3.2 years showed the economic justification of the project. IRR sensitivity analysis indicated that sales revenue, operating expense, and capital expense have the highest degree of sensitivity to the economic justification of the project, respectively. Also, the most important factor affecting the NPV was the discount rate fluctuations, so that in the ranges of 21% -38% discount rate, the project is economically justified. Manuscript profile -

What life drives man towards is in the direction of inner Cognition, which the religious elders also pointed to and paid attention toit. At the same time, what the mystics, scholars, thinkers and sages proved for centuries is now in the science of psychology under the title of projection as one of the defense mechanisms of the psyche. Self-knowledge and a kind of self-knowledge that requires an analytical look at the inner states. Sages and elders like Attar realized the importance of this issue and its index in the matter of life centuries before. Attar's in-depth analyzes and his attention to various aspects of human behavior and personality are evident in Tazkerat-Al-Owliya. In this regard, the current research is an interdisciplinary research whose purpose is to trace the reflection of the concept of projection as one of the concepts of psychological science by referring to numerous evidences in Tazkerat-Al-Owliya. The results of the investigations show that in Tazkerat-Al-Owliya, the diversity of the subject has caused the diversity of projection, which can be seen explicitly or implicitly, examples and evidence of the concept of projection, and Attar's perception of this concept is not significantly different from the opinion of psychologists.

These nations are mainly categorized as developing countries and are heavily dependent on capital, management & the advance trchnology of Oil majors for exploitation of their underground reserves. On the other side the foreign Oil companies (FOCs) require security and a promising long term profit to secure any investment in host countries. These two groups mainly come together and enter in to agreement within what we refer to as Oil & Gas contracts in which the parties stipulate and agree on all the terms and conditions as well as their financial expectations thereof. Factors such as restrictions posed by legal systems, public’s historical background, economical and political status of the nation a long with several others may motivate or discourage a country as to adopt or avoid a certain type of contract. Adopting a certain type of contract may in long run affect the outcomes drastically either towards or against interests of host countries.

On the other hand, in classic scheduling case, the focus is on balance between time and cost of carrying out projects, which in such a situation, one of possible solutions to shorten time of implementing project is to accelerate activities. In addition to imposing more costs, this acceleration can also affect the quality of performance and environmental effects. Therefore, in this study, the environmental effects and the quality of the activities were also considered as new indicators the cost-time balancing issue of the project. A new mathematical model with four indicators; cost, time, performance quality and environmental effects are provided. Unlike the traditional models in which only one execution mode was considered to perform the activities and one type of prerequisite relationship between the activities, the execution modes of the activities are multi-mode and the dependency relationships between the activities are generalized from the type of prerequisite relationships and including these types of relationships, brings the issue closer to the real world. Because the problem is NP-hard in large dimensions, meta-heuristic algorithms were used to solve the model. Manuscript profile -

Evaluating a portfolio of all its dimensions is an urgent and vital need in investment organizations. Therefore, in this research, a two-stage multi-objective mathematical model was evaluated and the project portfolio was selected. Due to the uncertainties in the evaluation of the project portfolio, the theory of firm uncertainty based on Bertsimas and wire were developed on a mathematical model and then due to the NP-HARD being the problem under study, to validate the model in larger dimensions using two algorithms. The meta-initiative of MOPSO and NSGAII analyzed the model findings. Based on the analysis of the results obtained from the two algorithms, it was shown that the computational time of MOPSO algorithm is better than NSGAII algorithm and the means of the first and second objective function of MOPSO also showed the superiority of this algorithm compared to NSGAII. Other analytical parameters such as NPF, MSI and SM showed that the NSGAII algorithm performed better than the MOPSO algorithm. Finally, using TOPSIS method, it was shown that NSGAII algorithm with a weight of 0.6945 was more favorable than MOPSO. Manuscript profile -

In other words, the higher the technological capabilities and growth rates, the higher chances of successfulness in an organization. Considering this, the essentiality of measuring technological capabilities of an organization by evaluation of the R&D effectiveness or calculation of the ultimate costs, which has been spent on the R&D procedures, seems obvious and vital. Therefore, in this study, based on the previous studies and the extraction of factors affecting technological capabilities as well as identification of cause and effect loop, a dynamic model has been developed. Then, using DeMetal technique, the relationships between them and the effective coefficients are determined and included in the model. Finally, in order to examine the accuracy of the modelling and determination of both state and rate variable’s behavior, data was gathered from eight science-based companies located at for knowledge-based companies applying for admission to the Securities and Exchange in a 24 months period. Analysis of the behavior of variables in these Informations not only showed the accuracy of the proposed model, but also confirmed its fluidity. Manuscript profile -

There are no suitable risk allocation models for Guilan construction industry based on article 23 processing budget and planning law 1352 clause about (EPC).There is the cost of project and plan for design risk allocation model. This work endeavors to propose and apply a Risk Allocation Model (RAM), based on a simple mechanism for allocating critical risks to the responsible party in the project. In addition, the RAM aims to compare among projects, which is more risky. The construction of RAM is based on Delphi method for 41 risk factors, over 10 groups, are identified and used in the model development. All factors are analyzed and weighted by deploying Weighted Risk Factor (WRF) which combines the effect of a risk factor probability and its effect on time and cost. The model results identified the most important risk factors to be allocated to owner, contractor or shared between them, as well as the suitable risk action for each factor. The model is applied on a real case study through two construction projects in Guilan to test the validation. A complete comparison between the two projects is presented and a decision is introduced for contractor. The results emphasized that the model is easy to understand and use by the parties involved in construction projects. Further, it is flexibility in the event of variables. Manuscript profile -

Owing to the emergence of these surfaces, the configuration of Girehs in Islamic architecture became incompatible with them. The traditional structural principles of Girehs expand two-dimensionally, whereas free surfaces expand irregularly and three-dimensionally. Gireh-work is considered one of the original and identity-giving decorations in Islamic architecture. To identify and develop contemporary architecture and past architectural achievements, it is necessary to find a strategy for projecting Girehes on free surfaces based on historical authenticity. The Islamic architecture of Iran has had many valuable achievements that can be applied to contemporary architectural challenges. In Iranian Islamic architecture, the dome and Gireh decoration play a crucial role, so the Iranian architect has tried to match these two elements using the geometric features of the dome and Gireh. As part of a qualitative research process, two examples of Iranian domes have been selected and analyzed with a descriptive-analytical approach in order to answer the following question: how Gireh’s geometrical principles on domical surfaces can be applied to contemporary free surfaces? In order to project Gireh onto the dome, a network based on radial gore segments was used as part of the projection technique. Transferring Girehs based on this network causes congruence homogeneity. Topological models of free surfaces are based on NURBS lines, making it possible to discretize and define the points on them. This makes it possible to apply anisotropic congruence transformation to Gireh projections on free surfaces. Manuscript profile -

Also, creating, presenting and maintaining value are the three key components of value management in the effectiveness of organizations, especially project-based organizations. Both approaches; hard value management (Structures, Strategies, Systems) and soft value management (employees, skills, styles) in the management paradigm can be a source of value creation and it depends on the type of management perspective that which source is to be used, here, the interaction between employees and managers is as the source of value creation. The purpose of this study is to provide a model for creating value from the manager social interactions with employees. The snowball sampling method was carried out by selecting 23 managers with more than 10 years of experience in project-oriented organizations. The results show that the manager can use 20 main categories of strategy to create value in the minds of employees when interacting. However, the categories related to contextual and intervening factors that are effective in using strategies have been taken to consideration. Also, the manager can create value in the minds of employees by integrating or combining both hard and soft approaches in project management. Manuscript profile -

The EU, founded with the cause of forming a federation, is now facing the challenge of divergence and division. Assuming cultural differences and different identities at national and sub-national levels in EU as underlying assumptions, this research by using analytical- descriptive method tries to understand the dysfunctions of EU common policy on identity- building? In response to the question “what are the impacts of national and sub-national identities including ethnic, religious and cultural on the integration of EU?” the hypothesis has been given here is that “the national and sub-national identities of EU through forming resistance identity in two levels of national and sub-national making the most important challenge for the project identity of EU based on integration. The tendencies to national and sub-national identity increased in comparing to super-national identity. Despite EU’s efforts to making policy on common identity, the levels of supranational loyalties are far away from the expected level. In turn, the predisposition toward national and sub-national and also separating from supranational identity. The EU approach of common identity making is project one which is in contradiction with the procedural nature of identity. This issue causes reaction and strengthening of resistance identities visa versus the instructional nature of EU project identity. So EU witnesses the increasing of national and sub-national divergent across the EU members. Manuscript profile -

Due to its strategic position and access to international free waters, Chabahar has a special place in exchanges between Iran and elsewhere. But the main competitor, or indeed, the neighboring port of Chabahar, is the Gwadar port of Pakistan, at the tip of the southwest of Pakistan on the Gulf Coast Gulf in the Oman Sea. Gwadar port found significant strategic value in India-Pakistan competition. China, as a global emerging power, is investing in strategic spheres, such as Gwadar, in order to connect Europe and exploit the North-South Corridor, So that it can continue to excel in the global economy. With the investment of China, at the port of Gwadar, most likely based on the economy and trade in the region, a new game will take shape, which will have implications for the region, including the Chabahar port of Iran. Considering this issue, this research deals with the descriptive-analytical method and library and documentary studies to study the geo-economical characteristics of the Chabahar and Gwadar ports. The research findings show, given the geographic and functional characteristics of the regions, the development of Chabahar is not going to weaken Gwadar, but faster development of Gwadar means weakening and even destroying Chabahar.

In such environments, the advancement of technology and the reduction of the lifespan of products and services lead to their rapid obsolescence. Project portfolio management capabilities can improve innovation decisions and new product outcomes, thereby giving organizations a competitive edge. In this research, the orientation of the research is developmental-applied and in terms of the type of research, it is qualitative-exploratory. In the following, using a multiple case study and the foundational data theory method and using semi-structured and in-depth interviews, as well as reviewing related documents, focusing on a number of successful innovative companies in the field of equipment manufacturing and production in Iran's electricity industry, Data was collected and analyzed in the form of open coding, central coding and selective coding. The findings of the research indicate that the portfolio management capabilities of innovation projects can be categorized into four main components: "process", "structure", "employees" and "knowledge base". Also, based on the results of the research, the elements and components of the theoretical research model (performance improvement model) including causal conditions (organizational factors, environmental factors and project and portfolio factors), background conditions (industry platform and technology platform), intervening conditions (capabilities parent organization, project management capabilities), interaction and action strategies (use of process capabilities, structure, staff and knowledge base) and outcomes (IPPM performance and business performance) were identified. Finally, in order to validate the final model of the research, the focus group tool was used to achieve appropriate validity in this research and increase the validity of the extracted model.
