The purpose of this study was to determine the comprehensive performance evaluation criteria to improve the performance evaluation system of employees using a new model of data envelopment analysis based on 360-degree evaluation for employee ranking.

In this study, first, performance evaluation criteria were identified by studying the research background. Questionnaires designed based on the opinions of twenty-five staff of the organization, three senior managers, ten professors with university experience and ten active and selected students of the university (a total of 48 people in a 360-degree structure) are completed and then using A new model of designed data envelopment analysis, employee ranking, was performed. 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 behavior 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.

Interpretation and analysis of structured results obtained from the use of data envelopment analysis policy based on 360-degree evaluation can be the basis for improving human resources and continuing periodic evaluation to continuously improve employee performance in the organization.

Originality/Value:

The present study can help their evaluations by using various indicators comprehensively as well as 360-degree approach and considering the external and internal challenges of the organization.

In this research, an algorithm for evaluating and ranking the branches of a financial and credit institution is presented that can evaluate the performance in a period of time 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 in accordance with the organization's strategy is located, this can facilitate the decision of experts to select effective and weighty indicators to them.

The performance of branches in various time 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.

Using the proposed algorithm, 51 branches of Keshavarzi Bank in Sistan and Baluchestan province are ranked. 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.

Terminals are major urban passenger centers that play an important role in collecting demand and distributing it on the network. The proper functioning of terminals depends on their proper planning, an important part of which is devoted to their principled location. The issue of locating intra-city bus terminals should be considered as optimization issues.

 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. In the third stage, the cost of construction and acquisition, the value of access to adjacent uses, as well as the amount of coverage that each candidate points provide in the city, are evaluated. 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. In order to better understand the proposed method, the problem of locating terminals was implemented in the city of Shiraz, which finally selected the proposed 3-point algorithm as the final points for the construction of intercity bus terminals.

Examination of the results of the model and parameters of selected points shows that these points are among the important and effective points for the construction of the terminal and are relatively in good agreement with the policy of Shiraz Municipality Bus Organization in locating the terminals.

Originality/Value:

In this paper, an innovative method is used to solve the problem of locating terminals, which strengthens the existing knowledge.

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 main purpose of this study, the relationship between economic growth and environmental degradation was retrospectively examined in the framework of EKC hypothesis.

This research has been done as an original paper using keyword analysis methods. The statistical sample of the research includes 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 records were related to scientific articles, of which 122 records were allocated to articles with keywords. Accordingly, these articles were considered for analysis.

On 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 and cannot be the right criterion for adopting and implementing appropriate economic-environmental policies.

Originality/Value:

Using a composite index showing all the dimensions related to environmental pollution and to be a true representative of environmental quality, can provide a more accurate analysis of the EKC hypothesis in future researches.

The purpose of this study was to measure the impact of stock liquidity on future investment in companies listed on the Tehran Stock Exchange.

 For this purpose, 95 companies during the period 2012-2019 were selected as the sample size of the study. The research method is descriptive-correlation and multiple regression using panel-data method has been used to estimate the regression model with panel data and for analysis.

The results of this study showed that stock liquidity has a negative and significant effect on the company's future investment. The results show that there is no significant difference between stock liquidity and corporate future investment in large and small companies as well as companies with information symmetry and information asymmetry.

Originality/Value:

This means that the size of companies and the speed of information dissemination in the market do not affect the relationship between stock liquidity and future investment and the market reacts to any information.

The Effect of working capital management on the firm's profitability in the companies listed on the Tehran stock exchange.

The sample of the study consisted of 125 companies that have between 2014 to 2019 were studied. 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.

The result of this study showed that there is a significant inverse relationship between the profitability of companies with receivables collection period and between the profitability of companies with inventory turnover period significant relationship was not found. In other words, 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 by used proper management of working capital take steps to increase the value of the company and thus increase the wealth of its shareholders.

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.

In this paper, we review DEA models for estimating input / output levels and applying manager or decision maker preferences, as well as improving inefficient units over a period of time. Finally, we have implemented the obtained models in 24 supervisory branches with four input indicators and four indicators, in one of the banks, and the results have been presented and interpreted in the form of several tables.

The results show that management can increase the index of attracting new customers in proportion to the ability of the collection in the input indicators.

Originality/Value:

The problem has been implemented on the unit under the second evaluation and has shown the results in different cases, although this is important for all units under evaluation.
