Purpose: This study aimed to determine the comprehensive performance evaluation criteria to improve employees' performance evaluation system using a new data envelopment analysis model based on 360-degree evaluation for employee ranking. Methodology: This study first identified performance evaluation criteria by studying the research background. Questionnaires designed based on the opinions of twenty-five organization staff, three senior managers, ten professors with university experience, and ten active and selected university students (48 people in a 360-degree structure) are completed. Then, employee ranking was performed using A new model of designed data envelopment analysis. Twelve performance evaluation indicators extracted from the research background by experts in four categories with the titles of service compensation system in the first category; Job security, perceived organizational justice, perceived organizational support, and physical working conditions in the second category; Job characteristics, job clarity and ability of employees in the third category and job feedback, job stress, organizational citizen behaviour and motivation in the fourth category were ranked and documented using a linear optimization model based on the goal programming and policy. Data envelopment analysis resulted in a complete ranking for the staff of a university unit with 25 staff members. Findings: Interpretation and analysis of structured results obtained using a data envelopment analysis policy based on 360-degree evaluation can be the basis for improving human resources and continuing periodic evaluation to enhance employee performance continuously. Originality/Value: The present study can help their evaluations by using various indicators comprehensively and a 360-degree approach and considering the external and internal challenges of the organization.

Purpose: In this research, an algorithm for evaluating and ranking the branches of a financial and credit institution is presented that can assess the performance in a period and manage the jump or stagnation of cross-sectional performance of branches. In the algorithm, the possibility of separating the criteria into two efficient and effective groups per the organization's strategy is located, which can facilitate experts' decision to select effective and weighty indicators for them. Methodology: The performance of branches in various periods is expressed as a fuzzy number. The structure of the fuzzy TOPSIS method is used in the algorithm. A new step of grouping the criteria to calculate the value of the criteria related to the fuzzy TOPSIS technique has been added, and the calculation formula has been described. Mechanism The reason for the superiority of the branches in terms of the whole to the part is expressed using the similarity matrix. Findings: The proposed algorithm ranks 51 branches of Keshavarzi Bank in Sistan and Baluchestan province. The reason for scoring the top three branches, middle and bottom of the ranking table, based on the similarity matrix, is discussed. Originality/Value: 1- Generating a decision matrix with fuzzy numbers based on the performance of multiple sections 2- Providing a structure for the possibility of separating indicators into two categories: efficient and effective 3- Formulating and weighing sub-indicators in proportion to the degree of dependence on the index head.

Purpose: Terminals are major urban passenger centers that play an essential role in collecting and distributing demand on the network. The proper functioning of terminals depends on their adequate planning, a necessary part of which is devoted to their principled location. The issue of locating intra-city bus terminals should be considered an optimization problem. Methodology: The mentioned method is based on four consecutive stages, according to which, in the first and second stages, the candidate points for the construction of intercity bus terminals are selected according to the network of bus lines and the location of the lanes, as well as according to the existing terminals. The construction and acquisition cost, the access value to adjacent uses, and each candidate point's coverage are evaluated in the third stage. Finally, in the fourth stage, the problem is transformed from a multi-objective mode to a single-objective maximization problem using the ideal planning method, as a result of which the top points are identified among the candidate points. To better understand the proposed method, the problem of locating terminals was implemented in Shiraz, which finally selected the proposed 3-point algorithm as the final point for constructing intercity bus terminals. Findings: An examination of the model results and the parameters of selected points shows that these points are among the important and effective points for constructing the terminal and are relatively in agreement with the policy of Shiraz Municipality Bus Organization in locating the terminals. Originality/Value: This paper uses an innovative method to solve the problem of locating terminals, strengthening existing knowledge.

Purpose: Although the relationship between economic growth and environmental degradation has been supported by theoretical justifications from empirical studies, including the EKC curve, it has not yet gained sufficient comprehensiveness and acceptance. Accordingly, in line with the primary purpose of this study, the relationship between economic growth and environmental degradation was retrospectively examined in the framework of the EKC hypothesis. Methodology: This research has been done as an original paper using keyword analysis methods. The statistical sample of the study includes the Web of Science (WOS), Scopus search engine, and Scientific Information Database (SID). About 1340 records were extracted in various formats, such as articles, books, conferences, conferences, abstracts, and notes. Among these, 340 were related to scientific articles, of which 122 were allocated to articles with keywords. Accordingly, these articles were considered for analysis. Findings: On the one hand, considering the different and contradictory results that have been the result of the work of many researchers in this field, and on the other hand, given that the type of environmental indicators used in all these studies is not a comprehensive indicator for the environmental quality, the obtained results will be invalid. They are not the proper criterion for adopting and implementing appropriate economic-environmental policies. Originality/Value: Using a composite index that shows all the dimensions related to environmental pollution and is a true representative of environmental quality can provide a more accurate analysis of the EKC hypothesis in future research.

Purpose: The present study aims to assess the effect of working capital management on the firm's profitability in the companies listed on the Tehran stock exchange. Methodology: The study sample comprised 125 companies studied between 2014 and 2019. In this study, the variable "net income before deducting interest and taxes to total assets" as a measure of the profitability of the variables, the period of collection of receivables, inventory turnover period as capital management criteria in circulation in variables, firm size, sales growth, the ratio of current assets to current liabilities ratio of financial debt to total assets and operating profit were used as the control variable. Findings: This study showed a significant inverse relationship between the profitability of companies with receivables collection periods and those with inventory turnover periods. Managers can reduce the period with the debt collection company to stay within reasonable limits and increase profitability. Originality/Value: It is expected that companies, using proper management of working capital, take steps to increase the company's value and thus increase its shareholders' wealth.

Purpose: Examining the history and growth trend of developed countries and comparing it with developing countries shows that the difference and strength of these countries is the optimal use of opportunities and facilities they have had. The study aims to describe the methodology and findings of a survey to assess the effectiveness of DEA models in estimating input/output levels, incorporating managerial preferences, and improving efficiency over time.Methodology: This paper reviews DEA models for estimating input/output levels, applying manager or decision-maker preferences, and improving inefficient units over a while. Finally, we have implemented the models obtained in 24 supervisory branches with four input indicators and four indicators in one of the banks, and the results have been presented and interpreted. Findings: The results show that management can increase the index of attracting new customers in proportion to the collection's ability in the input indicators. Originality/Value: The problem was implemented in the unit under the second evaluation and showed different results in different cases, although this is important for all units under assessment.
