These include such lean production, JIT, TQM, and the relationship between buyer, supplier and finally the customer satisfaction. The main purpose of this paper is to explore the relationship between three main components of production management in today’s industries namely supplier, buyer and engineer partnership in Iran Industries. An attempt also has been made to create closer collaboration in car manufacturing – and contemporary trends in production theory such as lean production, agile manufacturing and high performance production system. The model of Supply Network Leadership (SNL) has been developed in this paper for assessing the interrelationships between the supply chains with respect to the national objectives based on the national motivation of Iranian economics and industries. The SNL has a marco view on the interrelationships between the above mentioned objectives such as, imports substitution, export promotion, entrepreneurial activities, technology acquisition, quality of life improvement, etc. The leadership capabilities for any hierarchy determine the degree of size, complexity, executive penetration and power of network. The SNL acts like a cell, any resource absorption from the environment is the special task of BUYER, and all internal supporting and Human resource effectively and any associated processing is the special task of SUPPLIER and finally any duties related to growths, evolution and generation can be viewed as the special task of ENGINEER. We have argued that the SNL may hold lessons for the Iranian automobile manufacturing. The emphasis on flexibility and more customization may be especially appropriate. Manuscript profile -

Fuzzy linear regression analysis is the generalization of regression models that is appropriate using all data based on a specific criterion. This paper uses an adaptive neural fuzzy inference system to analyze and predict a non-parametric fuzzy regression function with non-fuzzy inputs and symmetrical trapezoidal fuzzy outputs. To this end, a new hybrid algorithm is proposed in which fuzzy minimum squares and linear programming are used to optimize secondary weights. Algorithms are applied by multi layer validation to validate models. More precisely, the accuracy of the algorithms with simulations is fully confirmed. Finally, two simulation examples were used to examine the efficiency of the model, in which the data were defined as trapezoidal numbers and by teaching them and specifying the number of rules used, the unknown parameters were estimated.

Though IT has traditionally been viewed as a contributor to waste within lean production, we suggest that modern developments in IT and the onset of hybrid ‘‘push-pull’’ production control mechanisms have allowed ERP and lean approaches to converge towards a state where ERP systems can in fact be used to support the deployment of lean practices. This paper analyses typical lean and ERP implementation processes contained within the scientific literature, and by further examining a concurrent implementation process in real-time, we develop and propose a process for ERP-based leanimplementations. Our findings suggest that the implementation of a contemporary ERP system can act as a catalyst for the application of lean production practices. Manuscript profile -

Sugar MoreBackground and Objective: Energy consumption in food industries is high and increasing due to the growing population, inadequacy of cultivating farms, and life condition improvement. This growing consumption is a threat to the environment and human’s health. Sugarcane industries are considered as high consuming industries which have a tangible impact on the environment and emission of greenhouse gases. Sugarcane industrial energy consumption share among other industries is 4.3% and more than 70% in total energy of food industry consumption. The purpose of this study is to investigate the impact of CMD application on the reduction of fossil fuel energy consumption and GHGs emission reduction in Haft Tappeh Sugarcane Factory. Method: The results of the factory energy auditing indicated that one of the proper methods to benefit from CMD is to replace the old boiler which has low efficiency with a new boiler. Pre-feasibility assessment of the environmental and economical aspects of implementing the project has been calculated using “Proform” software. It ran through three scenarios assuming the investment, installation, and maintenance costs; the new boiler consumption rate with higher efficiency and cost-effectiveness of replacing the new system with the old one having lower efficiency. Calculation was based on carbon credit value in global market. Results: As results show in case if scenario C is applied, the Net Present Value (NPV) will equal 21,000,000 dollars and Internal Rate of Return (IRR) will become 39.18%. Carbon credit was considered 20 dollars based on the reduction of CO2 equivalent which was calculated by carbon supply and demand market for CERs of CDM projects that are sold and purchased in carbon exchange market. IRR is higher than 16% discount rate; consequently, it proves that implementing such a project is cost-effective. Provided that the new high efficient boiler is used, the emission of CO2 equivalent during implementing the project-25 years- will reduce to 763,353 ton equal to CO2 equivalent; furthermore, 13,607,000 GJ is saved on consumption of natural gas. Conclusion: Considering the boilers with high energy consumption and low efficiency in this factory, the replacement of old boiler with the new one through CDM project is cost effective Manuscript profile -

This area is one of the nine reserves in Iran, and 66.5% of it is covered by forests. In this study, land capability evaluation of this area for forestry was carried out in Geographic Information System (GIS) surrounding. Method: Both Boolean and weighted Linear Combination (WLC) methods along with analytical Hierarchy Process (AHP) were used. First, the ecological characteristics of the study area including elevation, slope, soil texture, climate, value of vegetation type, soil depth and vegetation density were studied and then the calibrated model for forestry in Arasbaran area was created. Findings: In the first step, land capability assessment was done using Boolean method and results showed the presence of class capabilities of third, fourth, fifth, sixth and seventh, and lack of class capability of first and second for forestry. In the next step, the importance of criteria and sub-criteria was calculated using expert’s comments and AHP technique in Expert Choice 11. Then, land capability assessment was done using weighted linear combination. The results showed that all of the seven suitability classes for forestry were proper in the area. Discussion and Conclusion: Mc-Harg systemic model has been used to evaluate the ecologic capability evaluation for many years. The new process in ecologic capability evaluation is to use the mathematical models and to use the analytical hierarchy process for determining the weights and relative importance of the alternatives and for ecologic capability assessment by geographic information systems (GIS). In this study, to evaluate the forestry ecologic capability, both Boolean and WLC methods were used and the advantages and disadvantages of them were investigated. Manuscript profile -

Rangelands of MoreAbstract Background and Objective: Rangelands are very important in country economy in terms of grazing livestock, soil and water conservation and other services to the community. Therefore, systematical and careful management of these lands is necessary. Rangelands of Golestan province were one of the best rangelands of Iran in the past. However, high rate of population growth and sever dependence of the population to natural resources and rangelands caused plant coverage degradation. Floodwater spreading is one of the corrective practices that can be performed with certain goal in the rangelands. Site selection and prioritization of the areas suitable for floodwater spreading and infiltration of flood into the groundwater table are among the most important stages of these projects. Method: GIS and AHP model have been introduced as a suitable method for site selection of the areas appropriate for floodwater spreading system in the Gorgan Rud watershed. In this the Boolean scouring method with two values was used and compared with AHP method. Findings: Initially, the unsuitable areas were determined by AHP method. Then the remaining options derived from model results based on the comments. By site selection, the suitable areas were identified and the obtained inconsistency factor (0.08) proved that criteria weighing for locating the suitable areas for floodwater spreading is correct. Discussion and Conclusion: The results of this study also showed that the areas suggested for floodwater spreading are near the wells and springs, especially in the north and north-west of the watershed. Results showed that investigation of natural factors and constraints based on the Boolean method was not suitable for locating the appropriate areas for floodwater spreading in Gorganrud watershed.

The purpose of the article is to interpret the current situation regarding the right of citizenship, according to access to clean air, and the corresponding laws in Iran. To achieve this goal, European countries and corresponding laws have been chosen as benchmarks. Finally, providing solutions in the form of reasons for not defining the corresponding human rights laws and implementing them in the field of clean air will be the ultimate goal of the article.Methods: The current research is of the type of applied research, especially, the inferential approach and the analysis of the existing conditions by the author were the main paths in the final impressions.Findings: In Iran, the issue of guaranteeing the human right to clean air and its enforcement mechanisms has not yet found its real position in the legal system, specifically, elements such as the need for large investments, long-term and researched planning, and access to modern technologies for industrial use. The main challenges in defining and implementing citizens' rights are in the issue of access to clean air. In contrast, the European Union has always been a pioneer in creating a specific legal system in the field of dealing with air pollution.Conclusion: According to internal and external reports and standards, the level of air pollution in Iran violates the rights to life and health, children's rights, and the right to live in a healthy and sustainable environment. In Iran, there is no sufficient legal system to restore citizen's rights in the issue of clean air, or if there is, they are not fully implemented Manuscript profile -

These issues include an uneven distribution of the population across the country, an accelerated rate of urbanization, and environmental degradation as a result of poor site location. An appropriate site location in accordance with industrial principles is a significant step towards improving the environment, nation-wide industrial development and also principled and logical rural and urban growth. This research uses the high capabilities of GIS systems in collecting, analyzing, and managing data. Digital maps and environmental criteria were obtained from executive departments and field trips. Using the Boolean Method at the scale of 1:250,000, the researchers combined the maps that provide limitations to evaluate the environmental implication of industrial estates in Qom Province. In Stage Two, overlaying the maps of the current industrial estates with those maps of the limitations indicated that Shokohiyeh Industrial Estate has no limitation (except the southern part of it). The second phase of 325 hectare was fully covered with the limitation map and the 1000-hectare development plan was located to be in the permissible zone. The current developmental phases of Mahmoodabad Industrial estate are located in the permissible area. Also, the current location of Salafchegan Industrial Estate is sporadically located in the prohibited areas. Given the above research the location of Shokohiyeh and Salafchegan industrial estates is not appropriate. This requires the industrial units to firmly adhere to environmental principles particularly those related to pollutant units in Salafchegan. Although the location of Mahmoodabad Industrial estate appears to be appropriate, it is still very important to supervise the environmental impact of these units in reducing the pollution.

The sample size was 77, in which 24 were in the experimental group, 26 in control group 1 and 27 in control group 2. In the experimental group cooperative teaching method was used and in control groups the traditional teaching method .The tools were Evans and Jarvis’ group tendency questionnaire (1986) and researcher-made academic achievement tests.All the tests were consistent in terms of validity and reliability coefficient (0.86). To analyse data, both descriptive and inferential statistics (MANCOVA) were used.MANCOVA test showed significant differences among the tendencies of the three groups (P=0.001). Benfroni’s post hoc test results showed that the experimental group was affected more by cooperative teaching method compared with the other two groups (control group 1 with (P= 0.004) and control group 2 with (P=0.005)). But there wasn’t any significant diffenrence among the three groups considering academic achievement (P=0.646). Although this difference is not statistically significant, comparison of the averages of academic achievement in three groups showed better performance of experimental group. Teachers should learn active teaching methods and apply them in their classes. Also they should take measures to change students’ attitudes toward group work. Manuscript profile -

This study has identified and prioritized the potential of ecotourism sites in the Kojur basin of Mazandaran province. Physiographies criteria, including slope, direction, and elevation, as well as criteria of distance from road, river, village, sliding locations and canopy percent, were selected as the appropriate index. The criteria were evaluated and fuzzy by the experts and Analytic hierarchy process (AHP) method. Subsequently, using the Ordered weighted average (OWA) scenarios, the appropriate ecotourism site was selected. To reduce risk and increase managerial power, Boolean logic was used. The results showed that the landslide and the roads had a maximum value of 0.315 and 0.238, respectively. The output maps of the OWA scenarios have shown that the northeastern range of the cougar basin is the most optimal location for the establishment of the ecotourism site, and the northern region was ranked next. In the scenario of the low-risk level and non-compensated, and low-risk level and low compensation scenario, 83 hectares of land were recognized for the appropriate ecotourism site. While, average risk and complete compensation, high risk and low compensation, average risk and non-compensation and high risk and no compensation, were 3179, 1255, 1909, and 2577 hectares respectively for ecotourism sites. The Boolean logic output showed that about 47 hectares of northeastern lands of Kojour basin are an appropriate ecotourism site. Manuscript profile -

However, achieving this goal is not possible without eliminating waste. Lean production method is used as a way to reduce waste. The main philosophy of lean production in one sentence can be "the elimination of any activity and process that does not create value." Such activities are called wastage. This is achieved by techniques called lean manufacturing tools. The lean literature offers a variety of methods for identifying and disposing of waste, but many organizations still face several difficulties in implementing lean manufacturing systems. This study tries to use Triz as a powerful, efficient and structured tool that has opened a different perspective in the field of defining and solving problems facing human beings, to reduce waste in the driving force industrial company and use its problem-solving tools as solutions. Introduce effective in order to achieve pure principles in this organization. For this purpose, Topsis technique was used as one of the most efficient MADM methods and more efficient Triz tools in achieving pure principles were identified and prioritized based on effectiveness. According to the ranking results of Triz tools, the splicing tool is in the first priority, which is an analytical tool that plays a key role in structuring the problem and analyzing the situation, and directly eliminates the loss and creation of value.

One of the factors that threatens the environment is the phenomenon of haze that has affected many provinces of Iran in the past decade and today threatens the right to life of citizens and even many animal species. On the other hand, considering that many countries face this environmental risk, in addition to domestic actions, joint actions of countries should not be ignored. For this reason, in recent years, laws and agreements have been introduced at national, regional and international levels, but they have not been able to affect the management of haze phenomenon. In addition, measures must be taken within the country that prevent or minimize the penetration of haze phenomenon, These measures have been mentioned in laws such as the Clean Air Act, the Environmental Protection and Improvement Act, and the Executive Regulations on Combating the haze phenomenon, but unfortunately they have always faced challenges; Therefore, in this study, while emphasizing international actions, these challenges and limitations have been addressed and solutions have been proposed to eliminate them in order to manage haze phenomenon.

In the UCG, the process involves the injection of steam and air or oxygeninto an underground coal seam and igniting and burning of coal in-situ to produce the combustible gas. Previousstudies showed that many parameters affect site selection of UCG design. These characteristics including coalseam properties (thicknesses, depth, dip, resources, rank), faulting, discontinuity, properties of hangingwall andfootwall of coal seam and hydrogeological regime. In this paper, by studying Tabas Mazino coal basin andconsidering proper UCG site selection criteria, potential coal layer was selected for the UCG based on theControlled Retraction Injection Point (CRIP) method. The result of this investigation showed that the M2 coalseam has the highest rank (considering the seam thickness and reservoir) for the UCG operation in Mazino coalbasin in relation to other coal seams namely, M1,M5,M4andM2-1.

The existence of archaeological sites from the Paleolithic period to the late period shows the attention of humans to this area, and suitable environmental conditions can be considered as the reason for this tendency to settle in this area. In the past few years, several Lower paleolithic sites were discovered in this geographical zone during various and scattered surveys. These areas, which are deliberately located in the south of the lake and on the terraces of the rivers in this area, illustrate the existence of settlements from the Lower Paleolithic period and the Acheulean tool making industry. According to the technology used to make the artefacts and the typology of the pieces, the Shahrikand area can be related to the Lower Paleolithic period. Manuscript profile -

Thus, identification and assessment of the factors hindering the realization of the expected productivity of the production flow layout is the important. One of these factors is waste; Organizations can make layouts and production stream productive by following up lean thinking model, thereby producing final products with minimal waste. Helps organizations aware of the loss, up to making the right decisions in order to remove those that do not create any added value in the product, apply. Since the measurement of waste, or people's reasoning was based on the knowledge of experts and it is also subjective judgment, the information is ambiguous and linguistic variables in most the criteria. Therefore, there is a powerful technique that can be used on the basis of vague information, it is necessary.

In this regard, on MoreToday, due to the ever-increasing competition between organizations and uncertain environments that have been created by many changes in customer needs, using an efficient supply chain can be considered as a competitive advantage for any organization. In this regard, one solution is lean approach. Lean approach helps to eliminate waste in the supply chain. On the other hand, based on the state of Iran and the abundance of oil and gas resources, the implementation of lean approach in the supply chain of the organizations operating in this field is very important.In order to conduct this study, that has been carried out in one of the largest companies operating in the offshore sector and the objective is to achieve an supply chain. First, by reviewing the literature, eight key factors that lead to the lean of the supply chain were identified and using the tool of the questionnaire and distributing between statistical sample and statistical analysis were effective. Then, using an interpretive structural modeling approach, the research model was developed. In the next step, the model was validated in quantitative and statistical analyzes as well as qualitative and based on it, the factors: financing, leadership and management, and communication with the supplier were identified as the most influential and minimizing the delivery time and flexibility were identified as the most impressive factor. Finally, some suggestions were made to achieve lean procurement process in the offshore sector of the oil and gas industry. Manuscript profile -

Both cleanliness and uncleanness are very important issues in the religious jurisprudence that understanding their nature from real and not real points of view may cause some basic changes in the field of cleanness and uncleanness. Now the question is whether cleanness and uncleanness are considered as real issues or nominal issues, what are the necessities and consequences of both views? Researching of the received religious percepts in the field of cleanness and uncleanness indicated that despite of lack of vividness in the nature of cleanliness and uncleanness from the viewpoint of real or nominal because of explicit reference of religious percepts criteria in the cases these proofs considered from high potential in proving and extracting of reality of cleanliness and uncleanness. The researcher not only considered the religious percepts in the field of cleanliness and uncleanness but also studied the criteria for religious percepts and concluded that cleanliness and uncleanness are a real affair which can be a matter of nominal religious percepts, and in that religious speeches they did consider cleanness and uncleanness for all things with attention to the real presence of both.

The current study was aimed to compare the efficiency of three cleanup columns (immunoaffinity, MycoSep < sup>TM #225, MycoSep < sup>TM #227), applied for the determination of DON in cereal products, using high-performance liquid chromatography (HPLC). At first, wheat flour samples were spiked with DON at three concentrations (200, 700, 1200 ng/g), then recovery values were measured after cleanup with the columns. The amount of DON was also measured in 60 samples of cereal products (wheat flour, rice, barley flour, noodles and bread). The results showed that the highest recovery value (between 87.4±2.5 to 95.2±2.2%) was obtained from the immunoaffinity column. However, there was no significant difference between the immunoaffinity column and MycoSep 225. The lowest recovery value was obtained using MycoSep 227 column (P <0.05). The results also showed that 30 samples out of 60 (50%) were contaminated with DON. However, none of the samples exceeded the Iranian Standard limit (1000 ng/g). The highest contamination level (724.3 ng/g) was observed in a rice sample. The study showed that although the immunoaffinity column was more reliable in DON determination, MycoSep 225 showed promising recovery values. In addition, more precaution and measuring controls should be practiced by regulatory agencies to prevent mycotoxin contamination. Manuscript profile -

Quantum-MV algebras were introduced as non-lattice theoretic generalizations of MV algebras and as non-idempotent generalizations of orthomodular lattices. In this paper, we continue the research in the “world” of involutive algebras of the form (A, ⊙, , 1), with 1 = 0, 1 being the last element. We clarify now some aspects concerning the quantum-MV (QMV) algebras as non-idempotent generalizations of orthomodular lattices. We study in some detail the orthomodular lattices (OMLs) and we introduce and study two generalizations of them, the orthomodular softlattices (OMSLs) and the orthomodular widelattices (OMWLs). We establish systematically connections between OMLs and OMSLs/OMWLs and QMV, pre-MV, metha-MV, orthomodular algebras and ortholattices, orthosoftlattices/orthowidelattices - connections illustrated in 22 Figures. We prove, among others, that the transitive OMLs coincide with the Boolean algebras, that the OMSLs coincide with the OMLs, that the OMLs are included in OMWLs and that the OMWLs are a proper subclass of QMV algebras. The transitive and/or the antisymmetric case is also studied. Manuscript profile -

This algebraic structure aimed to capture the equational theory of the algebra of protoconcepts. We show that collections of fuzzy ideals and generalized fuzzy ideals are endowed with lattice structures.

This study analyzes the critical success factors (CSFs) in lean production extracted from 14 review studies. The interpretive structural modeling approach is utilized to analyze the impact of these critical success factors on one another. The aim is to enhance insights into lean production and facilitate informed decision-making. In this article, a seven-tiered model is presented. According to the conceptual model of success factors in lean production, leadership is positioned at the base of the model and serves as the origin for other factors. It should be regarded as the foremost critical success factor in lean production. When establishing lean production systems, organizations and senior managers should focus on higher levels and critical success factors that underlie the model. Subsequently, nonfuzzy and fuzzy driving and dependence power analyses were conducted that the fuzzy matrix cross-reference multiplication applied to a classification (MICMAC) analysis provides deeper insights into the analysis of driving and dependence power. The fuzzy matrix cross-reference multiplication applied to a classification analysis helped identify some key factors that are highly effective for successfully implementing lean manufacturing.

Considering the need to know this physiological characteristic in different fields of cycling and introducing them to athletes interested in this field; The aim of present study was investigating and comparing the body composition of mountain range and non-elite road cyclists in Shiraz city.Methods: In this practical and semi-experimental study, 20 road cyclists and 20 mountain cyclists (age 18-24) were selected as a statistical sample. Protein mass, mineral mass, soft lean mass and body fat percentage of the subjects were evaluated using the BOCA X1 Body Composition device made in South Korea. Kalmogorov-Smirnov and Independent sample t tests were used to analyze the data. Findings: There was no significant difference in protein mass (P=0.21), mineral mass (P=0.23) and soft lean mass (P=0.96) in road and mountain cyclists; However, the percentage of body fat of road cyclists was significantly lower than road cyclists (P=0.013).Conclusion: It seems that the two types of cycling have the same effect on body composition, but road cyclists had a lower body fat percentage than mountain cyclists; Due to the limitations such as lack of assessment of diet, aerobic capacity and heart function, more studies are needed in this field.

Considering the capabilities of this province in generating renewable energy, recognizing the potentials of clean energy generation and consumption, especially wind energy, should be a priority in the plans of managers and researchers. A descriptive, analytical and field approach is used in this study. The spatial capability of wind power plants in Mazandaran Province was evaluated using spatial and quantitative data. In order to initially estimate the energy that can be obtained from wind flow in the province, the necessary calculations were performed on wind direction and velocity information over a period of 12 years. Then, based on the group of experts, documentary and library studies, scientific resources in this field and available data, four climatic, economic, environmental-social and topographical factors, have been selected as the most important indicators to determine suitable areas for the establishment of wind power plants in Mazandaran Province. These four criteria include 18 sub-criteria and after weighting and overlapping, the final zoning map was prepared using the Boolean model. According to the final map, the central strip of the province within the boundaries of Noor, Amol and Babol counties, the northern parts of Noor and Sari counties, the south of Savadkooh and Qaemshahr counties, as well as the central and southern parts of Behshahr county, are more suitable areas than other parts of Mazandaran Province for establishing wind power plants.

At first, using the information of Environmental Protection Organization and Air Quality Control Department, Sorkheh Hesarbeh Park was selected as a clean environment and Azadi area as a polluted environment, and the desired plants were taken from these two areas. Leaf area in November (84) and June (85) and concentration of proline, soluble carbohydrates and amount of photosynthetic pigments (chlorophyll a, chlorophyll b, total chlorophyll and carotenoids) in July (85) were determined and compared by spectrophotometric method. The results of this research showed that air pollution caused a significant decrease in the leaf area in acacia and persimmon. Also, air pollution increased the concentration of proline in two plants, Acacia and Persimmon. Due to air pollution, the concentration of soluble carbohydrates decreased in acacia and increased in persimmon, and these changes were statistically significant. The results of this research showed that as a result of air pollution, the amount of photosynthetic pigments including (chlorophyll a and b and total chlorophyll and carotenoids) increased significantly in date palm, and in acacia chlorophyll a and total chlorophyll and carotenoids decreased, this decrease is significant in the case of carotenoids. and the amount of chlorophyll b did not change much.

However, the amount of these triterpenic acids can vary depending on geographical and cultivation conditions. For this purpose, jujubes grown in orchards of 29 different habitats from east, northeast, south, center, and west in different provinces of Iran were sampled at the end of the summer season. The triterpenic acids present in the dried jujube powder were extracted using 96% ethanol as a solvent, with a liquid-to-solid ratio of 15 mL/g, under ultrasonic waves at a temperature of 40 ℃ for 35 minutes. The extracted acids were quantified using high-performance liquid chromatography coupled with a UV detector. The obtained data were subjected to subsequent nested analysis and the Tukey test. The results revealed that only the average amount of betulinic acid significantly varied among the ecotypes. Furthermore, a hierarchical cluster analysis based on the diversity of these three triterpenic acids divided the studied ecotypes into four clusters. Cluster 1, representing Iran's eastern and northeastern regions, exhibited the highest amount of these triterpenic acids. However, analysis of variance between the clusters showed no significant difference among them. The results of the statistics show that the Climatic conditions, soil quality,seed and agricultural methods can be effective in changing or not changing the amount of triterpenic acids in jujube.

Among the various types of renewable energy resources, solar systems received more attention due to technical, environmental and economic reasons. However, the efficiency of solar panels is not high due to several reasons. In addition to using high-efficiency control equipment such as maximum power point tracking (MPPT) methods, cleaning the surface of solar panels is one of the best and easiest ways to improve their efficiency and performance. In this paper, to increase the efficiency of solar panels, a robot for cleaning solar panels with the ability to adjust the height with the help of tank wheel technology has been developed. Moreover, due to water shortages in the country, the design of this robot has been done without the use of water. Considering that the designed robot has a telecommunication system with remote control capability, the speed of cleaning is very high and there is no need for the operator. The used software in the robot provides proper scheduling for the cleaning of solar panels. In addition to the aforementioned advantages, the proposed robot has a much lower price than foreign products. The performance of this robot on the five kW solar power plant of Tafresh University has been evaluated. Increasing the efficiency of the power plant, more revenue from the sale of energy to the grid and significant savings in water consumption are the main advantages of this intelligent robot.

The overpopulation and the increasing need of food and thus the lack of agricultural products always rings the alarm. Thus with development of water resources and saving water, we can raise surface water irrigated fields and finally raise agricultural productivity. In this project, by using existing data from soil and water resources in the Central Desert, including provincesKhorasanRazavi and Jonoobi, Semnan, Isfahan, Qom, Yazd, Hormozgan, Kerman, Sistan and Baluchestan and by using Boolean logic and GIS software, suitable and talented areas, identified for the implementation of modern irrigation systems, And then based on the results of questionnaires, affecting factors of rejection the pressurized irrigation systems by farmers in desert areas were analyzed with SPSS software And finally by using sustainable agricultural development indicators of population, the population sustainable settlement, it was estimated. The results show that, with the proper use of water and soil resources and avoid wasting this valuable resource not only can be increase production per unit area index over the country and world but also by increasing acreage can be increase products in the range of 4 to 42 percent and establishment of population based on various indices in the range of 11 to 34 percent. While economic-administrative agent as the main challenge in the implementation of pressurized irrigation systems in desert areas were identified. Manuscript profile -

The research method was mixed (qualitative-quantitative) which was done with data foundation approach. The statistical population consisted of professors and specialists in the field of management, sports marketing, senior managers of the General Departments of Sports and Youth, heads of sports delegations and managers of sports halls in the west of the country who were selected by purposeful method. After studying the theoretical foundations, 12 in-depth interviews were analyzed and coded simultaneously. The qualitative part was used by Maxkiyoda software version 18 and in the quantitative part by SPSS software version 25 and Amos. Findings showed that the drivers of lean service success in sports organizations consist of six factors: value chain creation, value determination, value flow identification, perfection determination, value flow process and social value and lean service drive drivers. It consists of seven factors: lack of business model, inattention to customer feedback, long start-up time, poor marketing, structural problems, management problems and lack of employee participation, and based on them, a paradigm model was designed. Sports organizations in providing lean services to their customers are faced with special factors that by improving their quality can provide the basis for lean services. Manuscript profile -

The approach of lean management in production organizations has been widely used for productivity and organizational excellence, but unfortunately in the field of service organizations, especially educational organizations in Iran, little research has been done. In this article, the proposed model of establishing lean management appropriate to education, which consists of seven components: management and leadership, structure, human resources, communication, technology, process and organizational culture, is validated by experts. This research is applied in terms of purpose and survey type in terms of implementation method and also in terms of type and method of data collection and analysis is among the quantitative researches. The statistical population of this study is 20 specialists and experts in the field of education management who were selected by purposive sampling and snowball sampling. Data collection tools included a researcher-made questionnaire with Cranach's alpha of 0.75. The results showed that the model of establishing lean management in education has a good validity.

The statistical population of the study consisted of managers, deputies, heads and educational experts in the headquarters and executive staff, and educational supervisors of the hospitals affiliated to the Social Security Organization (420 people). The sample size was 200 people according to Cochran formula and were selected by simple random sampling method. In order to collect information, a researcher-made questionnaire was used including 17 components and 126 items. The face validity of the questionnaire was verified through pilot implementation, content validity through comprehensive review of literature and expert judgment, and construct validity was confirmed by factor analysis and its reliability was estimated by calculating the Cronbach's alpha coefficient of 0.97. In order to analyze the data, descriptive statistics (frequency tables, mean, variance, standard deviation) and inferential statistics (Kolmogorov-Smirnov test and exploratory and confirmatory factor analysis) were used. The results of data analysis at the level of 0.01, 17 dimensions, and 117 components as dimensions and components of pure education in the social security organization showed that the overall effect of these dimensions was 63.73% and dimension of value stream (identification of waste and value-creating activities) had the highest share (84.52) and dimension of human resources management had the lowest share (0.48). The study of the status of education in the social security organization also showed that the average of each of the components is slightly higher than the average of the community but is still far from ideal. In this way, while developing the mechanisms of movement from the current status of education to the optimal and ideal situation, the final model of improving the quality of training based on lean thinking in the social security organization design and its degree of fitness, and the fitting of the proposed model with a strong amount was confirmed.

In the next step, the final questionnaire was prepared. Then, the relationship between the variables and the cause-and-effect relationships was carried out through the system thinking approach and Dimtel technique to confirm the cause-and-effect relationships according to the pairwise comparison questionnaire among ten identified experts. Also, lean construction was used as a solution to reduce waste production. Lean construction follows new rules and without using new technologies or updating equipment with minimum use of resources, minimum waste and maximum productivity in construction projects. The main purpose of this article is to use the concept of lean construction and the system dynamics method to identify the main causes of waste production in construction projects. The main focus of lean construction is to analyze waste production processes, improve activities to reduce waste production and increase performance in construction projects. First, the effective factors on reducing the production of construction waste were identified through previous researches, and then a survey (interview and questionnaire) was conducted with experts in the case study of the waste management organization in the metropolis of Isfahan. In the next step, 52 questionnaires were prepared and distributed in the case study of the research. After collecting the information, the data obtained from the questionnaire was analyzed using statistics after checking its validity and reliability. In the last stage, after confirming the effective factors in the production of construction waste and how they are related, in order to develop a conceptual framework, cause-and-effect diagrams were drawn. The statistical results showed that the first to third most important factors affecting the reduction of construction waste with lean construction approach, flow perspective, identification of waste from the point of view of transformation and identification of waste from the point of view of value were the most important according to the experts in the waste management organization. Also, cause-and-effect relationships were confirmed through Dimtel's method. As a result, considering the relationship of correlation as well as cause and effect relationship, the way of communication between variables has been rooted through cause and effect circles and systemic thinking Manuscript profile
