        The purpose of this study is to investigate the effect of management ability on the value creation in the chemical and food industry in 2012-2016 by using artificial neural network. Initially, with the implementation of the DEA model with a native model, the relative efficiency is determined for each company and by estimating a regression model, the management ability to each company is also determined. Then the value creation of the companies is measured by the average of the factors such as return on equity, Q Tobin ratio, return on investment, and wealth creation for shareholders. The neural network model used in this study is a multilayer perceptron with back propagation error training pattern. To evaluate the relative efficiency is used the GAMS optimization software and to measure the management ability used the E-Views and MATLAB software is used to train and test the neural networks model. The results show that the artificial neural network model in the food industry is better than the chemical industry. This model estimates the companies' value creation through the management ability and other input variables. Other research results, the management ability score in both industries is equal, but the average value creation of the companies in the food industry is higher than the chemical industry.

        Measuring the performance of a production system is an important task in management for purposesof control, planning, etc.Lord Kelvin said, “When you can measure what you are speaking about, andexpress it in numbers, you know something about it; but when you cannot measure it, when youcannot express it in numbers, your knowledge is of a meager and unsatisfactory kind.”Hence, management knowledge is a measurable science; if we can’t measure each subject, then wecan’t control then, and management is impossible. We know that the major criterion of performance isproductivity, and we should be able to measure it. Data Envelopment Analysis (DEA) can estimatesystematically the relative efficiencies of an organization. The efficiency of a organization can bebenchmarked using DEA. DEA presents a model for evaluating the performance of a set ofcomparable decision making units (DMUs). In this paper, we develop a new model for calculatingproductivity with data envelopment analysis. Manuscript profile

        Measuring the performance of a production system has been an important task in management forpurposes of control, planning, etc. The Balanced Scorecard allows us to do just that. BSC is widelyused in government and industry because of the clear representation of the relationship and logicbetween the key performance indicators(KPI) of 4 perspectives - financial, customer, internal process,and learning and growth. in the other hand , Traditional studies in data envelopment analysis (DEA)view systems as a whole when measuring the efficiency, ignoring the operation of individualprocesses within a system. We present and demonstrate a multi-criteria approach for evaluating everyprojects in different stages. Our approach integrates the balanced scorecard (BSC) and dataenvelopment analysis (DEA) and develops an extended DEA model. The input and output measuresfor the integrated DEA–BSC model are grouped in “cards” which are associated with " B S C ". Withefficiency decomposition, the process which causes the inefficient operation of the system can beidentified for future improvement. finally we illustrate the proposed approach with a case studyinvolving six banking branches.

        Limitation of resources is an undeniable fact, which is dealt with many organizations such as media organizations. Hence, improving the performance of resource utilization of these organizations is one of the most important concerns of the managers. As a result, a manager must evaluate the performance of their organizations frequently. In this paper, we intend to measure the progress and regress of Iranian printed newspapers between two times 2016 and 2017. The current study is applied in terms of purpose and uses the Malmquist Productivity Index (MPI), which is a very useful approach in Data Envelopment Analysis (DEA) to measure the rate of progress and regress of decision-making units (DMUs) under evaluation. The data analysis was done utilizing GAMS, which is a high-level modeling system for mathematical programming and optimization. After reviewing the performance measurement literature and interviewing with media management specialists and also experts from the Ministry of Culture and Islamic Guidance-Deputy of Press and Information Affairs, appropriate indicators were recognized and selected. The results of the comparison of intra-organizational indicators in two consecutive years of 2016 and 2017 represents that 29 units from 87 DMUs have experienced progress and 58 ones regressed. In order to improve the performance of the regressed units, an appropriate strategy has been proposed. Manuscript profile

        This paper presents a method for performance evaluation, ranking and clustering based on the double-frontier view to analyze the complex networks. The model allows us to open the structure of the “black box” and can help to obtain important information about efficient and inefficient points of the system. In this paper, we consider a three-stage network, in respect to the additional desirable and undesirable inputs and outputs and utilize the cooperative approach to measure the efficiency of the overall system. Due to the fact that, a conclusion implying only one of these two, optimistic or pessimistic views is one-sided and incomplete, so, in this paper we used the double-frontier to analyze the network. Moreover, a heuristic technique was used to convert non-linear models into linear models. After obtaining the effective and inefficient points of the network, the DMUs are classified into several clusters by the k-means algorithm.Finally, in this article, in order to apply the proposed model a factory producing dairy products with a production area, warehouse premises and a delivery point are simulated. This factory has been regarded as a dynamic network with a time period of 24 intervals. The results of the ranking showed that, the time periods, (10) and (1) were the best and poorest respectively, in context to the efficiency within 24 phases of time. Manuscript profile

        The most exchange volume in a country will be obtained through bank system whose correct function will have a determinant role in improving economic activities. Nowadays, the customer’s rating and accreditation subject has been considered more than before by the banks due to increase the volume of overdue claims and banks’ past over dues. One of the most important tools for controlling the banks’ credit risk is to implement the credit rating system and to recognize effective factors on withholding payment of the bank advances. The goal of this article is to investigate the relation between efficiency and risk in banking system. Based on this, with the help of data envelopment analysis method and the information related to evaluation, rating and interpretation of credit risk which has been suggested by three main rating institutes like “Fitch, Moody’s and Standard and Poor’s”, the credit risk of 24 legal customers of Arak Melli Bank was evaluated and the credit rate of each legal companies was determined and their quality analysis was expressed.

        One of the most complicated decision making problems for managers in supply chain is the evaluation of supply chain performance which can be done in different ways. Though several studies have been developed on supply chain performance evaluation based on balanced scorecard (BSC), a few studies focused on relationships among four perspectives of BSC. This paper focuses on these relationships, especially on relationships with feedback structures. For this purpose, after identification of the BSC’s more important factors in evaluation of the suppliers, DEMATEL technique is employed to determine feedback relationships among these factors and to attain to the critical factors from the influential and to be influenced point of view. Next, these factors are used as the inputs and outputs of data envelopment analysis (DEA) weak disposability model in presence of undesirable factors to evaluate the suppliers and determine their efficiency scores. Finally, the efficient units were ranked based on the Anderson-Peterson (AP) super efficiency model. The proposed procedure is applied as a framework to evaluate the suppliers of Pars Khazar Company.

        This paper proposes a new method based on the ideal input vector to estimate inputs of a given decision making unit (DMU) when some or all of its outputs are increased to maintain its current efficiency level. In other words, this paper studied the following question: How much would be the increase in the inputs of the DMU if the decision maker increases certain outputs to a particular unit in which the DMU maintains its current efficiency level? In this study, unlike other proposed methods, the above question was addressed using just the single-objective linear programming (LP) problems. The problem of estimation of inputs was investigated based on the non-radial models. Necessary and sufficient conditions are proposed for estimation of inputs using just the single-objective LP problems. In addition, the level of deficiency (if any exists) in each of the output components is specified. An example with real data is presented to illustrate our proposed method. Manuscript profile

        This paper examines the issue of handling outputs in DEA that occur at different stages in time. In some situations, the output set occur at the different period of time, meaning that the produced outputs at the first period of time impact on the production of outputs of next time . This problem setting gives rise to the phenomenon of time-staged outputs. Specifically, the two outputs occur at different points in time, meaning that one of them plays a dual role. In other words, the dual-role measure is considered as either the output of the first stage and simultaneously as input for another time period. This paper demonstrates a modification of the joint technology in order to yield the maximum efficiency of the evaluated units. A real case on ten business schools has been illustrated . This real example is applied to emphasize that the suggested structure can handle this situation appropriately. Manuscript profile

        In many organizations and financial institutions, we don't always have acsses to inputs and outputs to evaluate the decision-making units (DMUs), but rather only a ratio of inputs to outputs ( or reverse) might be available. In DEA, cost efficiency determines input standards based on input costs. In multi-stage network DEA processes, in addition to input standards, cost efficiency would determine the standards for intermediate vectors as well as using linear programming models. In this paper, we calculated efficiency values for each stage, as well as overall efficiency based on a proxuction possibility set (PPS) in three stage network DEA-R processes. Then, we suggest three stage network DEA-R (ratio-based DEA midel) processes which are a combination of data envelopment analysis (DEA) and ratio data then we will propose cost efficiency models in each three stage network DEA-R process. Afterthan, we will determine the standards for outputs and intermediate measures in each stage using the subject of cost efficiency . In the end, overall efficiency and cost efficiency will be evaluated among of 30 Iranian educational research centers during the first half- year of 2015 based on a three stage network DEA-R process.

        The relative efficiency of a set of decision makers with multiple inputs and outputs is obtained by analyzing data coverage. One of the main assumptions of the classic models of data envelopment analysis is to consider each decision maker as a black box. Also, the independence of inputs and outputs is relative to each other. In this paper, the performance of subway stations in Tehran is determined by considering the two stage network structure in which the first stage indicates efficiency and the second stage demonstrates its effectiveness, and then, with regard to the presence of indicators, the input depends on In the first and second stages, the two stage models were modified and the resulting model was used for 71 metro stations in Tehran, and finally, 3 effective stations and 2 stations were effective. In total, of the 71 stations, no one of the metro stations have been operating efficiently. Manuscript profile

        Data Envelopment Analysis (DEA) is one of the best tools for evaluating the performance of decision-making units. Traditional DEA fails to measure efficient and inefficient units and evaluate the performance of network systems, and traditional models of DEA do not pay attention to internal structures and intermediate values. For this reason, in recent years, DEA model, known as network Data Envelopment Analysis models, have been introduced, this models eliminated this deficiency by considering intermediate values. In this paper, DEA based on network two-stage and slack variables and triangular intuitionistic fuzzy data is used to identify the efficiency of units. At first, the two-stage DEA model is introduced and then the model is transformed based on intuitionistic fuzzy coefficients and variables and finally it is converted to crisp two-stage structures by arithmetic operators on intuitionistic fuzzy data. The importance of this model is to measure the values of slack variables, which based on the Tone and Tsutsui model optimizes the intermediate values for inefficient units and ultimately shows better inefficiency. Finally, the optimized intermediate values are considered in the proposed model and thus are improved the overall efficiency of the system. Manuscript profile

        To face uncertainty in the real world, the two value logic has gradually replaced the fuzzy logic. In some real world problems, accurate determination of membership value is difficult and decision- making is associated with uncertainty and hesitation. This new perspective manages the uncertainty caused by hesitation. Generalized trapezoidal hesitant fuzzy numbers (GTHFN), whose membership degree is expressed by several trapezoidal fuzzy number, is best suited to solve the decision-making problem in real life than real numbers. In this paper, we refer to a new concept called 'generalized trapezoidal hesitant fuzzy numbers' and its combination with data envelopment analysis. Using this information, we consider the deviation and the score values as input and output of the data envelopment analysis model in two stages respectively; then we used the result to construct a paired comparison matrix and eventually we prioritize the receivers decision making units. To use some concepts in the proposed decision making method, we first present some definitions of concepts such as the score and deviation functions from the generalized trapezoidal hesitant fuzzy numbers. Finally, a numerical example is presented for the proposed method to confirm its applicability, and the ranking result is compared with the methods of AP, TOPSIS with GTHF number and the weighted geometric operator in [7].

        Data envelopment analysis is a linear programming-based approach used to evaluate the relative performance of decision making units (DMU's) that perform the same tasks with multiple inputs and multiple outputs. Due to the optimistic view of the DEA in evaluating the performance of homogeneous decision making units, multiple units with a maximum relative efficiency score (equal to unit) are highly likely. Therefore, ranking models were presented to distinguish between efficient units. Cross efficiency evaluation is one of the most useful tools for ranking DMUs in data envelopment analysis. This model has two major flaws in implementation. First, it yields different results in the presence of optimal alternatives; and second, there is no compelling reason to use the arithmetic mean to integrate the cross-performance matrix results. In this paper, a new approach, inspired by the preferential voting process and the idea proposed in the TOPSIS method, is presented to combine cross-performance results in the presence of undesirable outputs. The results are then used to rank suppliers in the presence of undesirable outputs. Manuscript profile

        The performance and resources allocation in large organizations such as banks, universities, and airports are one of the most important indicators in organizational management science. In this paper, by data envelopment analysis, which is a very powerful method of evaluating the efficiency of organizations, we analyze and review the performance and resource allocation. The optimal allocation of resources in organizations is considered to be the most important tool for implementing a long-term strategy and program for them, and the policies and objectives of the organization's plan are reflected in resources allocation of the activities. Indeed, given the importance of future organizations' performance, managers, taking into account the efficiency of each unit, provide strategies for target setting and how to allocate resources, including human resources, financial costs, technological facilities, and so on. On the other hand, given that actual data in organizations are usually random and stochastic, this paper addresses methods for allocating resources with stochastic data. Also, in line with this research, we will devise strategies for allocating resources as well as confronting limited resources in stochastic data, which will result in a new model for data envelopment analysis. In this model, stochastic data are presented with probability distribution due to probability. One of the most valuable achievements in this paper is to resolve the problem of allocating appropriate and optimal limited resources with stochastic data. Finally, with numerical results, the advantages of the new model are shown in relation to the previous models with stochastic data. Manuscript profile

        Nowadays, evaluating the efficiency of entities and knowing how resources should be organized is a significant aspect in order to achieve optimal results. One of methods for the performance evaluation is data envelopment analysis (DEA). Also, one of the important DEA topics is the most productive scale size (MPSS) estimation. Due to the presence of undesirable factors in the production systems, models are suggested in this paper for evaluating MPSS and determining the largest and smallest MPSS (nearest and farthest points of MPSS) while undesirable outputs with weak disposability are available. Models proposed determine the role of environmental factors in the performance estimation of units. These models can be used in factories, hospitals and as well as environmental protection for continual monitoring on the environmental situation affected by industrial activities and also showing the impact of environmental factors in measuring the efficiency. We use data from the Chinese industry to present the theoretical results. Manuscript profile

        The trend of population growth and development of cities in recent decades has led to the use of vehicles, both private and public. Meanwhile, public transportation has attracted a lot of attention due to its economic viability. Therefore, urban planning officials and municipalities try to solve problems such as; Environmental pollution, heavy traffic congestion, insecurity on some roads, severe accidents on some roads and excessive consumption of fuel suitable for vehicles (including oil - diesel and gasoline) are to consider appropriate measures. Data envelopment analysis with appropriate mathematical solutions can be an accurate and comprehensive tool to investigate such situations, so that managers can use it to make the best decision and remove existing barriers. Our goal in this article is to determine the efficiency, satisfaction and productivity (productivity in efficiency, productivity in satisfaction) of public vehicles, specifically 10 bus lines in Mashhad, so that their productivity in three consecutive years 91, 92 and 93 has been evaluated and the ratio of productivity in satisfaction to productivity in efficiency of each line has been calculated.

        Cross-efficiency method is a useful tool for efficiency evaluation of decision-making units in data envelopment analysis. The issue of non-uniqueness of optimal weights in the cross-efficiency evaluation has reduced the usefulness of this powerful method. This paper introduces a new method for selection of weights profiles as the secondary goal in cross-efficiency with stochastic data. The issue of zero-weight which implies the exclusion of some variables from the assessments, is also addressed in the new proposed method. The provided weights selection method also reduces the weight disparity in the achieved weights profile. In the peer-restricted stochastic cross-efficiency evaluation, the new approach guarantees that different DMUs should not attach very different weights to the same variables. As the result, a common set of weights using the idea of similarity between sets of weights is achieved in the proposed computation method. Some numerical examples are also used for illustration and comparison purposes. Manuscript profile

        The basic assumption in data envelopment analysis patterns (DEA) (such as the CCR andBCC models) is that the value of data related to the inputs and outputs is a precise andpositive number, but most of the time in real conditions of business, determining precisenumerical value is not possible in for some inputs or outputs. For this purpose, differentmodels have been proposed in DEA for imprecise data over recent years and also severalresearches have been conducted on DEA that are able to evaluate efficiency with negativedata. The negative interval DEA pattern which has been introduced and used in the presentstudy, addresses uncertainty both in inputs and outputs and provides user with more stableand reliable results for decision making.Now, in this paper a model is presented that is able to compute efficiency interval of unitswith interval input and output that while some indicators can also be negative and then weprove that the efficiency interval that this model gives us is more precise compared toefficiency interval of models previously proposed and finally, ten decision making units(DMUs) with the negative imprecise (interval) data are investigated by the proposed modeland the results of the proposed model are compared with the results of the previous models.

        The first objective in any financial organization is to improve performance, and performance evaluation also is one of the best ways to advance operations in organizations. By utilizing different methods of performance evaluation, organizations can evaluate the effectiveness and efficiency of processes that are in accord with strategic objectives. In addition, the performance evaluation instruments can help organizations with resource allocation and appropriate distribution of these resources. So far, many performance evaluation methods have been introduced which among them, traditional approaches only focus on the financial aspects and do not concern the non-financial. This article primarily concerns the linking of strategy maps and performance indicators that provides a structure of performance evaluation for the Saderat Bank of Tehran; and in the next step evaluates efficiency of bank branches by using Data Envelopment Analysis method.

        Economics depends on the economic scale of planning. Economists study the characteristics of the production function, while community operating management focuses on demand realization, so that loss of sales or inventory prevents cost reductions and maximizes profits. However, companies with a lack of capacity need to achieve economies of scale and demand to realize them simultaneously, especially when corporate demand is fluctuating. But always the customer's demand is not equal to output, the demand level may be less than the maximum output level of the highest productivity scale (MPSS), between the highest output level of the MPSS and the maximum output level, or greater than the maximum output level. In this paper, we intend to find the highest level of productivity in relation to the demand for active insurance companies in 1396 in all three scenarios. In fact, we will examine the applicability of Lee's (2016) paper in insurance companies in Iran. Manuscript profile

        In Data Envelopment Analysis (DEA), it is assumed that the role of each factor is known asinput or output. However, in some cases, there are shared factors that their input versusoutput status is not clearly known. These are flexible measures. In such cases, determiningwhether a factor is input or output is ambiguous. Therefore, using fuzzy concept seems to benecessary.In this paper, a two phase procedure is proposed to fuzzy classification of flexible measures.In the first phase, applying the existing classification methods, an orientation of flexiblemeasures to aid in the definition of inputs and outputs is achieved. Through defining amembership function in second phase, the input versus output status of a factor is expressedby fuzzy notion. By the proposed method, the efficiency of a decision mating unit is defendedby a membership degree. We illustrate the proposed model in a practical problem setting. Manuscript profile

        Comprehensive methods must be used for portfolio optimization. For this purpose, financial data of stock companies, inputs and outputs variable, the risk measure and investor’s preferences must be considered. By considering these items, we propose a method for portfolio optimization. In this paper, we used financial data of companies for screening the stock companies. We used Conditional Value at Risk (CVaR) as a risk measure, because of its advantages. Data Envelopment Analysis (DEA) can be used to calculate the efficiency of stock companies. Conventional DEA models assume non-negative data. However, many of these data take the negative value, therefore we propose the MeanSharp- CVaR (MSh CV) model and the Multi Objective MeanSharp- CVaR (MOMSh CV) model base on Range Directional Measure (RDM) that can take positive and negative values. By using Multi Objective Decision Making (MODM) model, investors can allocate their capital to the stocks of portfolio as they like. Finally, a numerical example of the purposed method is applied to Iran’s financial market. Manuscript profile

        Congestion is a wasteful stage of the production process where outputs are reduced due to excessive amount of inputs. There are several approaches in data envelopment analysis (DEA) literatures to treat congestion. The concept of strong and weak congestion first developed by Tone and Sahoo [Tone, K., Sahoo, B.K., 2004. Degree of scale economies and congestion: A unified DEA approach. European Journal of Operational Research 158, 755–772]. Evidence of strong congestion occurs whenever reducing proportionally all inputs can increase all outputs. Tone and Sahoo extended the relationship between congestion and other economic concept such as marginal productivity. They proved that existence of strong congestion is hinged to negative marginal productivity. Nonetheless the definition of strong congestion is too restrictive, since it has severe condition of “proportionate’’ reduction in all inputs causes an augmentation in all outputs. So the number of strongly congested DMUs appeared to be limited. In this paper we define a new less restrictive definition of congestion namely “ strict congestion’’ which is identified if and only if a reduction in all inputs causes an increase in all outputs. Therewith this study first proposes a new approach for the congestion recognition. Then another scheme is presented to determine the status of congestion (weak or strict). The validity of the proposed approach is demonstrated using numerical examples. Manuscript profile

        Data Envelopment Analysis (DEA) is a mathematical programming technique for evaluatingthe relative efficiency of a set of Decision Making Units (DMUs) and can also be utilized forsetting target. Target setting is one of the important subjects since according to its resultsefficiency can be increased. An important issue to be currently discussed, is to set targetwhile considering share data. These data for each individual indicate the share of the unit,which takes part in an activity, from the whole amount which is a predefined constant. It isobvious that the sum of units’ share is equal to the entire amount. Thus, any changes in themagnitude of these data has to be dependent on the changes in data of other units. In thispaper a two-stage procedure is developed to find benchmark units where share data exist. Thefact that all DMUs are jointly projected onto the new efficient frontier and simplicity, are thesignificant features of the proposed method. With a numerical example we demonstrate howthis method works. Manuscript profile

        In the performance evaluation process, using the classic data envelopment analysis (DEA) models, decision making units (DMUs) are considered as black boxes. While in many cases and different applications such as investment funds, banks, insurance companies, etc., DMUs have a network structure. In addition, in many network structures, some of the indicators used to calculate the efficiency of DMUs have an undesirable nature. Therefore, it is necessary to provide an effective approach that takes into account the internal structure of the DMus and the inter-organizational relationships in the calculation of efficiency and also is capable to be used in the presence of undesirable data. Accordingly, the purpose of the present study is to provide a network data envelopment analysis (NDEA) model in order to performance assessment of DMUs with a two-stage structure in the presence of undesirable outputs. It should be noted that according to the two-stage structure of investment companies and the presence of undesirable output in their evaluation process, ten investment companies from Tehran Stock Exchange have been selected as a case study for the research.

        This paper focuses on the efficiency measurement of health care system for Iran's provinces during the years 1383-86.The methodology is DEA (input and output oriented).Results indicate that there is so much room for increasing this efficiency. In order to determine factors affecting this low efficiency, by using panel data techniques, efficiency scores are regressed on variables which reflect both personal and social status of the provinces. Bad nutritional habits and individual health care expenditures are personal variables which have a negative effect on efficiency. On the other hand social variables such as per capita GDP and literacy rate move directly with efficiency. Per capita GDP has positive threshold effect. Noticeably, health care insurance expenditure as a social variable has a negative effect on efficiency which invokes attention of policy-makers in this area. As a result restructuring this industry, pave the way for higher efficiency Manuscript profile

        Background and Objective: Nowadays, increase of energy consumption in agricultural section has lead to some environmental problems and increase of final costs. In this study, the non-parametric method of Data Envelopment Analysis (DEA) is used to estimate the energy efficiency and greenhose gas emission in the irrigated wheat farms in Silakhor plain of Lorestan province. Method: Data were collected through both questionnaire and interwiew surveys using 150 farmers. Results showed that the energy consumption for 0.1 up to 2, 2.1 up to 5 and over 5 hectares were 22134, 24128 and 25078 MJ/ha respectively, and the sum of grain, fertilizer and pesticides had the highest share of energy consumption in  all levels. The results of DEA showed that technical, pure technical and scale efficiencies in the third level were 88, 93 and 94%and higher than the same amounts obtained in other levels. Results: Energy saving ratios in these levels were 6.83, 8.11 and 6.54 respectively. This indicates that 1512, 1957 and 1640 MJ/ha of total input energy can be saved, if the mentioned method is used. The results of greenhouse gas emission showed that diesel fuel has the highest share in the environmental pollutants. Optimization of energy consumption can totally decrease 6516.67 kg CO2 produced in wheat production. Manuscript profile

        Among the important producers and financial organizations in the national economy, the country's major producers, including petrochemicals and refineries, have an important role in improving efficiency and preventing crude oil. In this regard, managers of these organizations are struggling to improve efficiency in light of the economic conditions. The classic approach of data envelopment analysis models takes into account the linear pricing performance for inputs and outputs in the evaluation. In this paper, we examined the efficiency of the top ten petrochemical companies in the year 1395 by modeling with the help of auxiliary variables and nonlinear values ​​of inputs and outputs. An important feature of the proposed model is that it considers nonlinear values ​​of inputs and outputs. In the DEA total analysis, all weights are taken linearlyThey can not show the reality of the issue in many practical applications. Manuscript profile

        Evaluation of Tehran metro stations based on multiple indices has been studied in this paper. Subway stations have always been considered one of the service centers. Considering that the design and construction of the metro station focuses on the creation of infrastructure, facilities and equipment and then the operational part uses it for the first service, it therefore has two stages of construction and operation. Data envelopment analysis with two-step structure is designed for this topic. The data were collected over five years and attacked four Tehran metro stations. Based on the results of the designed model, the progress and remission of all stations were calculated at each stage and its relationship with financial investment in each metro station was investigated.

        Mutual funds are professional finance institutions which have invested in securities, by investors’ payments, while enjoying the professional management as well as decrease in non-systemic risk. On the other hand, investors require some approaches to evaluate the performance of mutual funds including, data envelopment analysis as a multi-purpose decision making method. Efficient and inefficient companies may be specified by this method, as well as a reference to achieve the efficiency limit for inefficient companies. This research aims to evaluate efficiency of mutual funds by the method of data envelopment analysis. The interval is begun from 2018 until the end of the spring of 2020 and all stock mutual funds form the statistical society. Also 35 mutual funds is a statistical sample. The results show meaningful correlation between obtained efficiency by the method of data envelopment analysis and the real output of mutual funds. So data envelopment analysis is a suitable method to evaluate efficiency of mutual funds. The results indicate that increase in total assets of mutual funds enhance their efficiency. But the age of mutual funds does not affect their efficiency. Manuscript profile

        In analyzing relative performance, especially at the institutional level, the traditional data envelopment analysis models do not recognize vastly different and important activities as separate functions and therefore cannot identify which function may be the main source of inefficiency. Mutual fund families are a group of mutual funds that are established through one investment company. The aim of this paper is to evaluate the relative performance of 18 mutual fund families in Iran during the years 1396 and 1397, by implementing a two-stage DEA model that decomposes the overall efficiency of each decision making unit into two components of operational management efficiency and portfolio management efficiency. The results show that by decomposing the overall efficiency into two components, one can determine mutual funds with good performance from those of bad or poor performance. Also, the frontier projections of mutual fund families with poor performance is calculated in order to help management in managing the relative performance of each family. According to assessment results of 18 mutual fund families in Iran, they have poor performance in operational management which means that management of costs of the funds is poor. Manuscript profile

        AbstractInvestment in projects is one of the factors of economic growth and sustainable development in countries. 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.

        تحلیل پوششی داده ها (DEA) روشی برای ارزیابی عملکرد مجموعه ای از واحدهای تصمیم گیرنده (DMU) متجانس با چندین ورودی و چندین خروجی می باشد. . مدل های مختلفی برای محاسبه کارایی در DEA وجود دارند که یکی از آن ها، مدل مجموعه وزن های مشترک (CSW) می باشد، که به طور گسترده ای توسط افراد و متخصصان DEA مورد استفاده قرار می گیرد. در تحلیل پوششی داده های کلاسیک تمام مقادیر ورودی ها و خروجی ها به طور دقیق مشخص می باشند. با این حال این فرض ممکن است در مسائل کاربردی همواره برقرار نباشد. یکی از روش های مهم برای مقابله با داده های نامشخص، بررسی داده های تصادفی در DEA است. این مقاله مدل مجموعه وزن های مشترک را برای حالتی که ورودی ها و خروجی ها تصادفی هستند، توسعه می دهد. سپس مدل تصادفی وزن مشترک (SCSW) به یک مدل قطعی غیر خطی تبدیل می گردد. پس از آن مدل قطعی به یک مدل برنامه ریزی درجه دوم تبدیل می شود. . کارایی به دست آمده با استفاده از داده های تصادفی را کارایی تصادفی می نامیم. مفهوم ارائه شده در این مقاله با مثال عددی که مربوط به شعبه های یک بانک ایرانی است نشان داده می شود.

        تجزیه و تحلیل پوششی داده ها یک تکنیک مبتنی بر برنامه ریزی ریاضی برای تعیین کارایی واحدهای تصمیم گیری (DMU) است. در برخی موارد ، مدیر قصد ندارد یک منبع جدید اضافه کند ، بلکه یکی از منابع قبلی را مجدداً تخصیص می دهد. تخصیص مجدد منابع ممکن است با اهداف مختلف انجام شود و مزایای متفاوتی داشته باشد. به عنوان مثال ، بدون افزودن منبع جدید و تنها با استفاده از منابع یکسان ، آیا می توان بازده یک واحد را افزایش داد یا حتی کارایی کل سیستم را افزایش داد؟ در این مقاله ، یک مدل ریاضی ارائه شده است که می تواند برای تخصیص مجدد یکی از منابع موجود قبلی بین واحدها به گونه ای استفاده شود که کارایی کل واحدهای تصمیم گیرنده به حداکثر مقدار ممکن برسد. در این مدل ، به منظور جلوگیری از کاهش بیش از حد سهم هر واحد از منبع مورد نظر ، محدودیت هایی در نظر گرفته شده است. در این محدودیت ها ، حد پایینی برای سهم هر واحد مشخص شده است. همچنین ، تخصیص مجدد منابع به احتمال زیاد منجر به تغییراتی در مقادیر خروجی واحدهای تصمیم گیرنده می شود. در مدل ارائه شده ، برخی از محدودیت ها در نظر گرفته می شوند که حد بالایی را برای خروجی های تولید شده توسط واحدها مشخص می کند. محدودیت های دیگری در این مدل وجود دارد. اول این که سهم کل واحدها از منبع مورد نظر نباید از مقدار موجود آن بیشتر باشد و دوم این که کل خروجی تولید شده توسط همه واحدها باید حداقل برابر کل خروجی تولید شده قبل از تخصیص مجدد باشد. مدل ارائه شده در این مقاله ، علاوه بر در نظر گرفتن محدودیت های توصیف شده ، که همه آنها اجتناب ناپذیر هستند ، به یک مدل برنامه ریزی خطی تبدیل شده است که توسط بسیاری از نرم افزارهای موجود قابل حل است.

        Introduction: Cities are considered to be the main cause of instability in the world, and following the change in urban development and development factors, the discussion of sustainability and sustainable development regardless of residential neighborhoods and uncertain urbanization will be. Objectives: The purpose of this study is to analyze the indicators of sustainable urban development on the performance of Bonab neighborhoods. Methods:. The present article is a descriptive-analytical in terms of practical purpose and is a descriptive-analytical method for examining the criteria of sustainable urban development in the form of three selected indicators and 57 sub-indicators of urban sustainable development. For information analysis, Pearson correlation coefficients, multivariate regression, data cover analysis, cross -performance, sensitivity analysis, and SPSS and dea Slover software have been used. Results and Discussion: The results of this study showed that due to the input indicators and output of sustainable urban development of 8 neighborhoods (4, 5, 6, 7, 9, 10, 11, 13), with an efficiency less than one percent As an inefficient neighborhoods and 5 neighborhoods (1, 2, 3, 6, 8), they are recognized as an efficient unit in terms of sustainable urban development indicators. One of the most important factors in neighborhoods is a great use of inputs against the production of small outputs. Conclusion: Inappropriate spatial distribution of urban activities and facilities and services across the city, the life of the livestock, the inconsistencies between the organs and organizations associated with the planning in the city of Bonab, and the lack of optimal use of factors. That is the difference in the performance of neighborhoods. In the meantime, inefficient neighborhoods must change their input indicators to move towards sustainable urban development.

        Data envelopment analysis is used as a suitable tool to estimate the efficiency of companies that use production technologies with multiple inputs and multiple outputs. Classical data envelopment analysis models often do not provide accurate information about the status of units to managers and organizational policymakers due to the low resolution of units. In this research, the basis of the BCC model is the output oriented of data envelopment analysis and in order to increase the discriminate of efficient decision-making units from inefficient, the ideal data envelopment analysis model based on BCC was used and then to increase the resolution Decision Making Units A new model called the Modified goal Programming Model of Data Envelopment Analysis based on output-oriented BCC was used to measure performance. In this study, the management of Ghavamin Bank branches across the country was evaluated. The results of the research show the discriminate power of the modified goal programming model of data envelopment analysis based on output-oriented BCC compared to other data envelopment analysis models. So that out of 32 managements under review in Ghavamin Bank, the management of branches in the west of Tehran was identified as efficient using this model and the rest of the managements were found to be inefficient.

        Nowadays, human looks to tread a path towards optimized using of available resources, Therefore, due to the limitations of capital, time, location, energy, and so on, managers have sought scientific methods from the beginning to make the most of these constraints. one of the most important ways to achieve optimization is evaluating the performance of the Decision Making Units. The gool of this work is to evaluate the energy consumption in the Kohgiluyeh and Boyerahamd province industry considering the industries with 10 and more employees. As in the calculating of the energy efficiency, several outputs and inputs must be considered in form of the productiion function theory, the data envelopment analysis is used to calculate the energy efficiency in the industrial units. Then the results of the energy efficiency, existing barriers and the practical consideration will be explaiend. The results of the efficiency model show that the most important factor of the inefficiency of the province's industry is the large population of job seekers and is the lack of optimal utilization of the workforce in the province's industry.

        The most important reason for identifying the main indicators and calculating the efficiency of knowledge management performance in the oil industry is to maintain and classify the existing knowledge and create a strong global competitive advantage by making progress in developing production methods with new technology based on improving technical knowledge. The most important parameter of performance evaluation is efficiency; there are different methods to measure it. Data envelopment analysis is a powerful tool for calculating system efficiency, including knowledge management performance in the oil industry. In this research, the main indicators of knowledge management were identified using library resources and practical publications. By surveying the employees of oil industry companies with data envelopment analysis and hierarchical analysis techniques, the efficiency of knowledge management performance was calculated, which can be used to rank the companies and planning to improve their knowledge management level. According to the results, the National Refining and Distribution of Petroleum Products Company has acted at higher level than other companies and has a good competitive advantage with its global competitors. The present study is the first study that has calculated the efficiency of knowledge management performance of four main Iranian oil industry companies with data envelopment analysis.

        Contemporary supply chains are complex networks of processes that are subject to many disruptions; a resilient supply chain will be able to respond more quickly to changes by creating capabilities. The effect of supply chain network components on each other under conditions of uncertainty contributes to complexity and disruption. The supply chain must be pushed towards a resiliency strategy in order to reduce disruptions and deal with issues that arise from the supply chain. The purpose of this paper is to analyze network processes from supplier to distributor, in proportion to the convergence of processes by a combination of resilience factors in the automotive industry. The design of the proposed scenarios with the combination of effective resilience factors is presented, which is based on the opinion of industry experts and also takes the vulnerable factors and disorders of each level into account. First, the sources of supply chain risks such as disruptions, delays and vulnerabilities are identified and then twenty-four scenarios are designed with a combination of resilience factors of flexibility, visibility, velocity, and visibility. The company''s complex supply chain is simulated based on the system''s past rate and statistical distribution functions, and then the network DEA is used to select the superior scenario. The indicators of each scenario or simulation output are selected based on the DEA, ranking the most efficient scenario. Finally, the relationships between them have been explored using mathematical analysis and the creation of a regression model between the simulation indices and the output of scenarios.

        Performance evaluation in data envelopment analysis is obtained by using technical efficiency calculation. But what is not taken into account in this type of calculation is the price of model inputs. In calculating technical efficiency, the amount of output to the input is maximized, and the model can be used to identify efficient decision-making units, while it is possible to determine the decision-making unit that is at the efficiency limit and a reference for other units. Decision-making systems are efficient at a high cost, and it is possible to find decision-making units that are on the verge of efficiency at a lower production cost. Cost Efficiency seeks to find points that are on the edge of efficiency at the lowest cost. Given the importance of cost efficiency and the lack of attention to this concept in network and multi-stage structures, this study investigates cost efficiency in a purely two-stage process. In the present study, using the concept of game theory and data envelopment analysis in a centralized and decentralized state, we evaluate the performance of purely two-stage processes. In order to investigate the validity and efficiency of the models and their applicability, a case study has been used in the Iranian electricity industry and some management results are discussed.

        Data envelopment analysis is the tool for computation in decision-making units such as supply chain. Since the model of two-stage data envelopment analysis has more focused on supply chain processes in two levels; the evaluation in higher levels has been essential to obtain more accurate efficiency. This paper extends Wang & Chin (2010) model into three levels for evaluation the supply chain to show the importance of integration in the overall supply chain. The model is considered the extended two-stage DEA model of Koa and Hwang(2008) to variable returns to scale (VRS) assumption and the additive efficiency decomposition model of Chen (2009) generalized to take into account the relative importance weights of two individual stages. The presented model is executed in numerical illustration and the results are analyzed in tables. Manuscript profile

        In today’s competitive environment in manufacturing and services process, the organizations are confronted with the need to have indicators and patterns for assessing the performance. The balanced scorecard is a successful instrument in implementing the strategic plans of the organization. The present paper aims to evaluate the performance and rank the branches of Tejarat bank in Yazd province based on their efficiency. The balanced scorecard is an appropriate device for designing and measuring the performance in terms of four perspectives including financial, customer, internal process and growth and innovation. This study also intends to use a combining model of BSC and fuzzy data envelopment analysis to evaluate the performance of the branches. This is a descriptive study using field study along with the library, observation and sometimes interview to gather the required information. The findings reveal that among the twenty-six examined branches, 11 branches are efficient. Additionally, the cross efficiency ranking has been used to rank the branches. Finally, the sensitivity analyses demonstrate that ATM has the highest impact on the efficiency of the units followed by the position and the number of employees. On the other hand, the total bank deposits have the least impact on the efficiency of the banks. Manuscript profile

The purpose of this study is to measure the ability of management in the cement industry with a new pattern has been member of the Iranian stock exchange. To do this, data from financial statements of companies at 2012 to 2016 years were used. First, by implementing a suitable model and regional Data Envelopment Analysis model, Relative efficiency for each of the companies is calculated and efficient units also have been ranking with Anderson-Peterson method. Then estimate a regression model, the index is calculated to management ability each of the firms. For evaluating the relative efficiency optimization software GAMS and to determine the ability of management software E-Views is used. We aim to achieve non-inherent ability of managers in units. The results of the research show that the efficiency or Inefficiency of the companies can be related to the inherent and acquired ability of managers. The results indicate that companies that have been evaluated with a score efficiently (For example; Iran Chalk Co. & Ardabil Cement Co.), not simply guarantee for high ability of their managers. While, some companies have been efficiently evaluated the ability of their managers is also high. For example; Khuzestan Cement Co. & Mazandaran Cement Co.  Manuscript profile

        The existence of an active and prosperous capital market is always recognized as one of the signs of international development in the countries. The most important issue faced by investors in these markets is the decision to choose the appropriate securities for investment and formation of optimal portfolio. The rating of companies accepted in stock exchange is a complete mirror of their status and is a measure of investment. This will increase the competitiveness, development and market efficiency. In this research, the top 20 companies listed in Tehran Stock Exchange during the third quarter of 2015 are ranked according to financial ratios. In previous studies, optimal portfolio has been determined using data envelopment analysis models and multi-criteria decision making techniques, but the present study combines these two techniques to evaluate and determine the most efficient portfolio. Accordingly, the performance scores of each model are obtained using one of the data envelopment analysis model and then, the weight of each index is obtained using the network analysis process through multi-criteria decision-making techniques.

        Covering models have found many applications in a wide variety of real world problems, nevertheless some assumptions of covering models are not realistic enough, that’s why a general approach wouldn’t be able to answer needs of encountering varied aspects of real world considerations. Assumptions like unavailability of servers in emergency circumstances, postponing the process of serving customers, inevitable uncertainty in real world and evaluating more factors at the same time, are a sort of assumptions which covering models always face them but they are not able to find any answer to them. Therefore, how to deal with these sorts of assumptions has been reminded a big question. In this research, for facing unavailability, we address Backup covering and for facing uncertainty in input data, we propose Interval Full-ranking model. Furthermore, by combining backup covering and interval full-ranking models (also conceptions), not only we can save time and evaluate more factors like efficiency and cost simultaneously, but also covering considerations in real aspects are reachable. In final, we have solved the proposed model by using precise methods and Genetic revolutionary algorithm in small and large scales, respectively in order to analyze evaluate and compare the results. Results demonstrate appropriate performance of the proposed model despite simultaneous consideration of the mentioned assumptions and none of the assumptions are mutually exclusive.

        In recent years, mathematical and operation research models are commonly used to assess efficiency and productivity of educational departments of universities and ranking them. Some sets of educational, research, and service activities are then considered as input and output indices of the models. Then, according to the importance and influence of indices on total performance of Decision-making Units (DMU), the efficiency score is defined as the weighted sum of outputs-weighted sum of inputs ratio. In this article, we obtained the efficiency score of 11 educational departments in two cases constant return to scale and variable return to scale using Data Envelopment Analysis (DEA). The results showed that 6 DMUs are efficient and 5 DMUs are inefficient. Manuscript profile

        One of the most important tools for calculating the performance of the decision making units (DMUs) is the quantitative and powerful Data Envelopment Analysis (DEA) technique which uses the past inputs and outputs of DMUs. Inability to estimate performance, using of definite inputs and outputs and inappropriate distribution of weights to inputs and outputs are the weaknesses of DEA. While in the real world, the DMUs are faced with more random parameters. So, this paper presents a new model to predict efficiency of DMUs based on stochastic data envelopment analysis in fuzzy environment, in which by integrating the random effects of environmental factors on inputs and outputs to resolve the problems. Finally, this paper presents a real application of the proposed model in banking industry for predicting the efficiency of branches. The results will be compared with the real efficiencies of branches. The high correlation between predicted and actual results indicates the accuracy of the proposed model. Manuscript profile

        In this paper, data envelopment analysis (DEA) was discussed for non-homogenous mixed network structure where the outputs of each stage can enter the next stage in the same or another layer as inputs or come out from the system as final products. In this model, in addition to intermediate inputs, each stage can also have independent inputs. For this purpose, a mathematical model has been developed in which the independent inputs and final outputs for the components of the decision making units (DMUs) are examined. To show the efficiency of the model, real data for 20 DMUs were used and the results were compared with those of traditional models. The results obtained from the proposed method eliminate the shortcomings of traditional methods for proper detection of units that are on the efficient border (with an efficiency of one). The developed method can provide the managers and decision makers with a more accurate understanding of the performance of components of DMUs. Manuscript profile

        Among the four economy markets, the labor market plays a pivotal role in establishing relations between supply and demand as well as in balancing the mass economic variables like employment. The socio-economic consequences of the balance in labor market are of great importance for economists and policy makers.  A direct consequence of such balance is the prevention of costs waste resulting from unemployment. Employment is a significant parameter in economic development, income distribution, and human self-esteem. On the contrary, unemployment causes a number of abnormalities with a wide range of economic, social and political aftermaths. Governments also consider unemployment as an important economic phenomenon and try to find solutions for this problem. It is observed that all countries, whether developed or developing, come across unemployment. The population structure of Asian countries and a great number of labor forces and lack of proper facilities have made unemployment the most important socio-economic problem. Globalization tends to influence the labor market structure, and (un)employment. As the developing countries play roles in labor market, they should be considered as an effective variable in the labor market. Manuscript profile

        Evaluation of the effectiveness of organizations has always been the concern of researchers. Hence, over the years numerous techniques for doing this have been proposed and used. One of the techniques that is widely used in various research areas and a high proportion of related scientific evaluation is data envelopment analysis (DEA). Besides, the insurance industry as a growing industry in the country has attracted the attention of researchers and administrators. Among the various issues in this area is the problem of performance evaluation and performance indicator. Because of the small amount of performance and its comparison in various branches and units, we can investigate different procedures in increasing the efficiency of the insurance branches and the steps taken to improve it. This study uses data envelopment analysis to measure the efficiency of insurance branches and after recognizing the efficient and inefficient offices by using technical tools, we have introduced the factors that are responsible for inefficiency of ineffective branches and finally we have presented some practical solutions to improve the performance of the insurance units.   Manuscript profile

        The favorable investment funds play a suitable role in economic growth and development of a country. Thus, the investment fund has a key role in guiding the capital investment. The study aimed at the performance net growth of investment funds. The research method was casual-comparative. In order to assess the total productivity changes the malamaqeist, s total productivity index in regard to its assessment growth regression was used. According to the previous researches, the beta coefficient of the fund, expenses and net asset value (NAV) at the beginning of each year was selected as input variable, and the average annual return on investment (ROI) from the time of establishment, and the end of the year (NAV) were used as output variable. Accordingly the total malmaqueist,s  productivity index was applied to the 19 common investment funds in 2013 and 2014 respectively. At the same time, mathematical expected growth of investment funds was compared with the status of each investment funds growth (regression) to neutralize the impact of environmental factors and assess the productivity performance growth in relation to each other. The results showed that the first mutual funds of agricultural bank with 314percent growth performance was in the first rank and gained the greatest growth rate and the joint funds of omid-saham with 38 percent regression had the greatest decline.

        بیماران قلبی علائم متعددی را نشان می دهند و اشاره به آنها دشوار است. تحلیل پوشش داده ها ((DEA یک درجه کارایی مقایسه ای برای هر واحد تصمیم گیری  (DMU) با چند ورودی و خروجی فراهم می کند. ارزیابی بیمارستان ها یکی از برنامه های کاربردی عمده در DEA است. در این مطالعه، مقایسه مدل جمعی با شاخص بهره وری مالم کوئیست (MPI) ورودی محور و خروجی مورد استفاده قرار گرفته است. MPI برای اندازه گیری رشد بهره وری نسبت به تکنولوژی مرجع محاسبه شده است. در محاسبه رشد MPI دو موضوع اصلی مطرح می شود. چه چیزی به طور کلی به عنوان اثر پیشروی و یا تغییر کارایی فنی (TEC) و اثر "تغییر مرز" یا تغییرات تکنولوژیکی (TC) اشاره می شود. داده ها شامل یک دوره شش ساله از سال 2011 تا 2016 برای 15 بیمارستان قلب محلی است. دو ورودی، یک عامل میانی  و دو خروجی در مدل دو مرحلهای انتخاب شده و این عوامل نشان دهنده عملکرد اصلی بیمارستانها است. تبدیل مدل دو مرحله ای به مدل تک مرحله ای معرفی شده است.این مدل برای اصلاح کارایی یک فرآیند دو مرحله ای وجلوگیری از وابستگی به وزنهای مختلف پیشنهادشده است. در نهایت، نتایج نشان داد که میانگین هندسی MPI در کارایی فنی خالص ورودی محور  در بیمارستان دهم (2.1517) به عنوان بالاترین  عملکرد بیمارستان  با بالاترین میزان  رشد بهره وری معرفی شده است.

        سازمان های پروژه محور در صنایع بالادستی سهم زیادی از منابع ملی را در اختیار دارند و نقش مهمی در توسعه یک کشور ایفا می کنند. ارزیابی عملکرد سازمان های پروژه محور می تواند به مدیران کمک کند تا از ورودی ها به طور موثر استفاده کنند و راه خود را برای دستیابی به اهداف هموار کنند. برای ارزیابی عملکرد سازمان های پروژه محور، شاخص های کمی و کیفی زیادی وجود دارد. محاسبه کارایی از طریق تحلیل پوششی داده ها (DEA) یک شاخص رایج برای ارزیابی عملکرد در چنین شرکت هایی است. در مدل سنتی DEA داده‌های واضح مورد نیاز است در حالی که در دنیای واقعی، بیشتر داده‌ها نادقیق و نامطمئن هستند. یکی از دلایل اصلی عدم قطعیت مربوط به اطلاعات غیر کمی، ناقص و دست نیافتنی است که باعث ادغام منطق فازی و مجموعه های فازی در مدل های مختلف مانند DEA می شود.ایدۀ اصلی پژوهش حاضر ترکیب رویکردهای کمی و کیفی در ارزیابی عملکرد برای بهره‌گیری از هر دو و دستیابی به نتایج دقیق‌تر است. از این رو، در این مقاله، یک مدل ترکیبی مبتنی بر تحلیل پوششی داده های فازی (FDEA) و مدل تعالی پروژه (PEM) برای ارزیابی عملکرد در سازمان های پروژه محور پیشنهاد شده است. ابتدا ارزیابی عملکرد توسط مدل PEM داده های فازی انجام می شود. سپس پیاده سازی فازی DEA در مدل PEM انجام می شود که در آن ورودی ها و خروجی های مدل FDEA معیارهای مدل PEM هستند. مدل هیبریدی پیشنهادی برای ارزیابی 30 شرکت پتروشیمی در ایران استفاده شده است. مقایسه نتایج هر دو مدل نشان‌دهنده ضریب همبستگی تقریباً 90/0 در سطح معنی‌داری 01/0 است که نشان‌دهنده همبستگی مناسب بین دو مدل است.

In the proposed model, this paper also considers the situation in which shared inputs are jointly consumed in each stage. We also assume some outputs can be produced by the first and second stages by using separate inputs. The proposed model is illustrated in an empirical example of twenty sale representatives in two provinces of Golestan and Mazandaran.

        هدف اصلی این مقاله، ارتقا و بهبود واحد های ناکارا به وسیله ی وزنهای مشترک به دست آمده از همه ی واحدهای مورد مطالعه می باشد. در واقع وزن های مشترک ورودیها و خروجیهایی که شامل داده های منفی است را به وسیله حل یک مدل برنامه ریزی خطی به دست می آوریم و بردار وزن ها را به عنوان جهتی در نظر می گیریم که واحدهای ناکارا در آن مسیر ارتقا می یابند. روش شناسی این تحقیق به این صورت است که، مدل شعاعی نیمه ماهیتی را مد نظر قرار دهیم و می خواهیم از دوال این مدل برای یافتن وزنهای مشترک ورودیها و خروجیهایی که برخی از آنها منفی هستند، استفاده کنیم. برای این منظور یک مسأله چندهدفه ی تولید وزنهای مشترک ارائه می دهیم و برنامه ریزی آرمانی را برای حل آن بکار می بریم که این منجر به تولید یک مسأله ی غیرخطی می شود که برای این مسأله ی خاص، توسط یک روش خطی سازی، آنرا به یک مسأله ی برنامه ریزی خطی تبدیل می کنیم. چون شرط لازم و کافی برای کرانداری مدل شعاعی نیمه ماهیتی در ماهیت ورودی (خروجی) این است که یک ورودی (خروجی) با حداقل یک مقدار مثبت موجود باشد، پس ما این شرط را در اینجا رعایت می کنیم. سرانجام روشمان را با ذکر یک مثال، بیشتر توضیح می دهیم و نکته قابل توجه در روش ارتقا دادن در تحقیق حاضر این است که داده ای منفی به صورت داده ای منفی ارتقا و بهبود می یابد.

        تحلیل پوششی داده ها (DEA) یک روش برنامه ریزی ناپارامتریک برای ارزیابی کارایی نسبی مجموعه ای از واحدهای تصمیم گیری متجانس (DMUs) با ورودی های متعدد و خروجی های متعدد است. روش کارایی متقاطع DEA روشی شناخته شده است که برای ارزیابی و رتبه بندی مجموعه ای از واحدهای تصمیم گیری متجانس استفاده می شود. هر زمان که یک DMU قصد ارزیابی سایر DMU ها را داشته باشد، با مشکل وزن های بهینه غیر یکتای مدل های DEA مواجه می شود. زیرا وزن‌های مختلف امتیازات متقاطع متفاوتی را به ما می‌دهند و این باعث سردرگمی تصمیم‌گیرنده در تصمیم‌گیری نهایی می‌شود. اشکال اصلی این روش، مجموعه راه حل بهینه چندگانه است. هدف اصلی این مطالعه پیشنهاد رویکردی برای حل این مشکل برای ایجاد امتیازهای کارایی متقاطع DEA غیر غالب است. ما یک مدل هدف ثانویه برنامه ریزی خطی را برای انتخاب مجموعه ای از وزن های بهینه برای هر DMU پیشنهاد می کنیم. روش پیشنهادی ما نه تنها ساده تر از روش های دیگر ارائه شده با همین هدف است، بلکه کارایی بیشتری دارد. مثال های عددی برای نشان دادن این موضوع در پایان آورده شده است.

        Equality in distribution of health facilities is one of the main indicators for increasing the availability of the general health index to the society. So, equitable access to health services for all people in a community leads to promoting the health and equal opportunities in the society. The aim of this study is the evaluation of equity in health by assessing people's access to health centers using the Geographic Information System (GIS) and data envelopment analysis (DEA) in Ardebil (with Descriptive and analytical Methods). DEA is one of the useful tools in understanding decision-making milieu, with the primary information processing. Thus, with taking advantage of the GIS the spatial index was provided. Hence, the access quality of the ARDEBIL citizen's to health centers by using of the spatial indicators in the structure of CCR-O model was evaluated. According to the results, the average efficiency of the urban core is the 0.45. Among the urban cores of Ardebil, only three urban cores have the perfect efficiency (Including a range of Shohada Square, Sharyati and 15 Khordad, and Shahriyar neighborhoods, Azadegan and the Garapache garden and the area around Shorabil). In Division of the efficiency to 3 categories in format of Quite efficient (1 = μ), acceptable (0.7≤μ) and unacceptable (0.7≥μ), areas in about 1,000 hectares with a 30 thousand residents of South-Central corridor position with over 6.5 km have the perfect and acceptable efficiency; of the total area of 6031 hectares and 421069 spectators of urban cores.

        Recognizing the significance of decisions and decision-making by the Islamic Parliament and their impact on human societies, it is crucial to evaluate the efficiency of different parliamentary terms, identify strengths and weaknesses, and determine influential factors for enhancing future performance. The reformation of the decision-making process is essential as it will result in sound decisions and elevate the political and economic conditions of the country. Thus, the objective of this research is to propose a two-stage data envelopment analysis (DEA) model to evaluate the performance of various periods of the Islamic Parliament (from the third to the tenth period) in terms of legislation and supervision. In the proposed approach, each term of the Islamic Parliament is considered a two-stage decision-making unit (DMU), with legislation as the first stage and supervision as the second stage. The results suggest that, generally, 50% of the periods are efficient, while the remaining 50% are inefficient. Specifically, Periods C, D, G, and H are identified as efficient periods across both dimensions. However, Period B, in terms of overall performance and the supervision dimension, and Period A, within the legislative dimension, are pinpointed as the most inefficient periods. Additionally, an analysis of the average efficiency scores in legislation and supervision underscores that, overall, the Islamic Parliament has demonstrated superior performance in legislation compared to supervision during various periods. This disparity in performance between the supervisory and legislative aspects has led to higher inefficiencies among the periods characterized as inefficient. Manuscript profile

        DEA-based clustering approach reveals the input–output relationships hidden in the data items of input and output. DEA-based clustering approach employs the piece-wise production functions derived from the DEA method to cluster the car companies. Estimate production function for each car company by input-output data is the benefit of this method. Thus, each car company (like Saipa) not only knows the cluster that it belongs to, but also checks the production function type that it confronts. It is important for managerial decision-making in different fields where decision-makers are interested in knowing the changes required in combining input resources. Manuscript profile

        The efficiency and productivity measuring models have changed a lot in past decade, and strong body of theories and software's have been developed. In this article, first we review microeconomic theories about efficiency and then explain two major efficiency measuring models include data envelopment analysis (DEA) and SFA.Recent arguments about efficiency criteria start with studies of Coopman and Farrell in 1951. He argues that the issue of economic efficiency measuring in an industry is important from two aspects: one, economy theories and two, for purpose of economic policy making. Economic planning applications in particular industries, have a significant effect on expecting more outcomes without allocating more incomes and resources (efficiency definition). Manuscript profile

        Classical data envelopment analysis models calculate the performance of decision-making units based on a common performance boundary and make no distinction between efficient units. In this study, the method of super-efficiency and cross-efficiency is used to rank the efficient branches of banks before the cooperation phase. Then, in the cooperation phase, each efficient branch is considered as a player and the subdivisions of the efficient branches are considered as a coalition, and the problem is examined using the method of cooperative game theory and Shaply value. In this study, the efficiency change variable shows the impact of each efficient branch in different alliances. From the total variable of efficiency change of efficient branches in each coalition, a characteristic function called profit from the coalition is introduced. The value of this characteristic function is determined for all possible alliances and Shaply value is introduced as the solution of this cooperative game and the ranking of efficient branches is presented in terms of cooperation. The resulting model is implemented on a case study and the ranks of efficient branches are compared in the super efficiency method and cross-efficiency (before cooperation) and Shaply value method (after cooperation).

        Banks play an important role in the economic development of any country as the main part of the financial system. Calculating efficiency and finding the strengths and weaknesses of branches has a significant impact on increasing the efficiency of banks. Data envelopment analysis is one of the performance evaluation techniques that is able to introduce benchmarks for inefficient decision-making units in addition to estimating relative efficiency. In this paper, using a data envelopment analysis, a model for evaluating efficiency, studying sensitivity analysis of 18 branches of one of the commercial banks of Iran with financial ratios is presented. For this purpose, a model is proposed for output estimating with ratio data. By changing the input values the output values can be estimated. The amount of changes required in the outputs to maintain the efficiency as well as maintaining the rank is possible by using the proposed model with ratio data. Manuscript profile

        In today's highly competitive world, the condition of survival and participation in the field of activity, functioning and efficient and effective, is not achieved except through continuous planning, monitoring, control and evaluation. In this regard, we tried to present a mathematical hybrid model for selecting and planning an optimal composition of the shares according to the goals and priorities, in order to obtain the highest compatibility between the final selection and the initial ranking of each share. The proposed model consists of three steps and several steps, the SBM method of data envelopment analysis (DEA) (for initial stock revisions, multi-factor decision-making (TOPSIS)) in uncertainty conditions, for the assessment and ranking of shares in two individual steps and categorized and integer linear programming (IP) for choosing the best stock portfolio with increased scores according to the organization's priorities and constraints. Collect information from reputable sites of five industries active automotive, pharmacy, petrochemical, cement and food industries to the best stock portfolio for investment, due to the impact of algorithms and methods.

        Data envelopment analysis is a non-parametric method for measuring the performance score of a set of units under evaluation. Recently, the application of data envelopment analysis models in networked or multi-stage structures has been considered by researchers. This paper seeks to reinforce the first steps taken to develop DEA network models based on asynchronous technology. To this end, it provides a way to consider undesirable outputs in an asynchronous technology. The models presented in this paper, while calculating the overall performance score in a network system, are able to calculate the performance of each step separately in the presence of undesirable factors without any additional calculation and provide it to the system administrators. Also, to show the accuracy of the proposed model compared to the basic CCR model, we conclude the computational accuracy of the model due to the identification of a number of less efficient units than the CCR model. According to the results, despite the fact that some units are considered as efficient, but due to inefficiency in some stages are considered inefficient and only the National Industrial Holding is considered as the only efficient unit due to the fact that it is efficient in both stages.

        The purpose of this study is to select the optimal stock portfolio using data envelopment analysis and to carry out the project of stock exchange information about the top 50 active companies in the summer of 1398 and trace the analysis of the same data in the spring of 1398. To calculate the relative efficiency and progress of companies, a developed data envelopment analysis (SORM) model has been used, where inputs can be changed only at a limited and specified distance, and with the same assumption, the output can be limited to a limited distance. The negative data can be analyzed and the final model facilitates the efficiency and optimization of stock portfolio selection according to the information extracted from the community under discussion. The results of this analysis show that 13 companies achieved a performance equal to 1, which indicates the highest level of efficiency, and Bank Saderat, including 1.32 Fanavaran Petrochemical Company, with the figure of 1.15, has been classified as having the highest progress and growth rate, respectively, on the first and second floors of productivity.Keywords: negative data, data envelopment analysis, ranking indicators, super performance, progress and regression.

        Today, measuring efficiency is one of the most important methods of performance evaluation in any organization. The outputs obtained in all inputs represent the efficiency. Due to the comprehensiveness of the banking sector, it can be introduced as one of the main areas of economic development. In this paper, a data envelopment analysis (DEA) model in a Free Disposal Hull (FDH) network is presented considering the undesirable output for handling the status of the financial deposits in Saman Bank branches. Since the basic models calculate efficiency by considering the overall output and input and ignoring the internal relationships in the banking process flow system; therefore, by considering this issue, in this paper, we present a DEA model that calculates the efficiency score of the branches with the high accuracy. Then the proposed model is compared to the basic CCR model. Finally, the cross-performance method is used to rank the units of the branches. Manuscript profile

        In the past, attempts have been made to conceptualize all purchases based on the LBO model and through the lens of agency theory. This view of the past has severely limited the ability of financial engineers to create models and tools for entrepreneurship motivation. ETA is a window to revitalize businesses by acquiring small businesses with entrepreneurial capacity instead of starting a start-up business.In this study, according to behavioral, financial, economic, social, and legal indicators, the efficiency degree of entrepreneurship through acquisition models using the non-parametric method of data envelopment analysis based on output-oriented BCC and CCR models from the entrepreneurs and investors' perspectives in the Iranian market. We have demonstrated a comprehensive ranking of the models based on the Anderson and Peterson (A&P) model finally.The results show that based on the output-oriented BCC and CCR models, the crowdfunding model from the perspective of entrepreneurs, and the incubator model from the perspective of inefficient investors.

        The traditional data envelopment analysis model allows the decision maker unit (DMU) to use the most favorable weights to evaluate the efficiency. This type of evaluation with the most flexibility can prevent the full ranking of DMUs and the evaluation results for DMUs are unacceptable. To solve this problem in data envelopment analysis, a common weight approach based on the concept of the degree of satisfaction of a DMU has been introduced. Also, to solve a common weight model, which is a nonlinear model, an algorithm is presented that can be modeled step by step. In this paper, we will evaluate the performance of companies active in Tehran Stock Exchange using a common weight model for 24 companies active in Tehran Stock Exchange. The weighted average performance of Tehran Stock Exchange companies for the years 1394 and 1395. The results show that this method will rank companies without any interference during these two years.

        Improving efficiency is one of the most important indicators to evaluate the Organization performance and the most basic and the first step to improve efficiency is measure and evaluate it. So far, little researches has been conducted on the hospitals performance evaluation using the combined of balanced scorecard (BSC) and data envelopment analysis (DEA). But in the researches has found by the researcher; 1. Simple performance of units has calculated using DEA classic models, which have two limitations: a) self-evaluation; and b) a lack of recognition between efficient DMUs; The new VFB-DEA cross efficiency model used in this research eliminates these limitations and makes the evaluation results more reasonable. 2. Conditions of uncertainty are not considered if some performance indicators require human judgment, to overcome this problem, the development of the VFB-DEA cross efficiency   model in fuzzy environment is done by the researchers. This research attempts by using fuzzy data envelopment analysis (FDEA) and BSC to evaluate the public hospitals performance in Mashhad during 2014. In this regard, the indicators used to evaluate the performance of health care in situations in past studies and with health experts, three indicators of Staff satisfaction, capita Education and the cost of medicine and supplies, and three indicators of patient satisfaction and the average length of stay and percentage of bed occupancy, in four perspectives of the balanced scorecards elected as input indicators and output indicators. Then, using a new model VFB-DEA in fuzzy environment, mentioned units were evaluated. The results show in the VFB-DEA model thehospital2is ranked first and the hospital 1 and 6 are the most inefficient hospitals. Given the uncertainty and determination of input and output indicators based on a balanced scorecard, the proposed model is more accurate than the past models and enables managers to make better and more accurate decisions to improve the efficiency of organizations.

        Given the very essential role of banks in Iran, their improper operations might generate a critical environment. The present study seeks to examine the efficiency and productivity of Iran commercial banks for a period from 2007 to 2011 by using Fuzzy TOPSIS, DEA and Malmquist index. For implementing this model, the significance of the inputs (total assets, equity, total costs and total debts) and outputs (total revenue, E-banking, granted loans and receiveables and currency trades) are calculated by using Fuzzy TOPSIS method to be used in DEA and Malmquist index. The findings reveal that the total assets (among inputs) and granted loans and receivables (among outputs) have the highest significance. The results of banks’ efficiency document that Mehr-e-Iranian, Sina, Sarmayeh, Pasargad, Karafarin, Maskan, Toseh-e-Saderat and Eghtesad-e-Novin have the best operation. The findings related to productivity also indicate that the average productivity rate of the banks are negative over the years from 2007 to 2011; except for Melli, Mellat, Sanat Madan, Saderat, Sepah, Tejarat, Keshavarzi, Parsian, Karafarin and Post Bank (the average productivity rate of these banks are more than one).
