        1 - Ranking of bank branches with undesirable and fuzzy data: A DEA-based approach

        Banks are one of the most important financial sectors in order to the economic development of each country. Certainly, efficiency scores and ranks of banks are significant and effective aspects towards future planning. Sometimes the performance of banks must be measured in the presence of undesirable and vague factors. For these reasons in the current paper a procedure based on data envelopment analysis (DEA) is introduced for evaluating the efficiency and complete ranking of decision making units (DMUs) where undesirable and fuzzy measures exist. To illustrate, in the presence of undesirable and fuzzy measures, DMUs are evaluated by using a fuzzy expected value approach and DMUs with similar efficiency scores are ranked by using constraints and the Maximal Balance Index based on the optimal shadow prices. Afterwards, the efficiency scores of 25 branches of an Iranian commercial bank are evaluated using the proposed method. Also, a complete ranking of bank branches is presented to discriminate branches. Manuscript profile

        2 - Analysis of environmental efficiency and marginal rate of substitution in the presence of undesirable factors: A DEA-based approach

        The balance between environmental regulations and economic issues has always been one of the main challenges of governments, because with the growth of industrialization, environmental pollution has also increased. Along with the desired outputs in the production process, may also produce undesirable outputs which have a great impact on organizations efficiency and environmental pollution. On the other hand, dealing with the impact of undesirable factors on the inputs and desirable outputs, valuable information for making strategies and organizational decisions could be achieved. Considering undesirable factors, this paper aims to calculate the relative efficiency and marginal ratios of environmental systems using weak and managerial disposability models of data envelopment analysis (DEA). This study is conducted in two phases. In the first one, the regions were classified into efficient and inefficient groups using a developed DEA model. In the second step, the marginal rate of undesirable outputs on the inputs and desirable outputs in efficient areas were calculated. The results showed that the change in the amount of undesirable outputs has a significant effect on other variables. Manuscript profile

        Legislation constitutes one of the most critical responsibilities of the Islamic Parliament. Given its pivotal role in addressing the country's political, economic, and social issues, evaluating this institution and identifying factors that influence its performance takes on particular significance. This necessitates the development of a suitable model for assessing its performance. Therefore, the primary aim of this research is to provide an efficiency measurement model for evaluating the legislative performance of the Islamic Parliament. To achieve this goal, considering that the Islamic Parliament primarily operates as a service-oriented institution where the consumption of inputs is not of utmost importance, we have utilized the technique of Data Envelopment Analysis (DEA) without explicit input data. Additionally, in consideration of the existence of undesirable outputs, we have applied the assumption of managerial disposability. Based on these considerations, we have determined and compared the legislative performance of the Islamic Parliament over eight periods (from the third to the tenth period) using models assuming efficiency on both constant and variable scales.

        4 - Optimization of the Private Sector Cooperative Approach in Investment Projects of the National Iranian Oil Company Using Game Theory Approach

        The aim of this research is to design scenarios based on cooperative game theory scenarios to examine the rewards and penalties observed from sharing or not sharing knowledge among companies. The statistical population of the study includes managers and experts from 10 subsidiary companies of the National Iranian Oil Company, among whom 10 senior managers were selected for pairwise comparisons using the snowball sampling method. The research method is classified as descriptive, applied, interpretive, exploratory, with a quantitative and qualitative nature. This study emphasizes the importance of efficient knowledge sharing as a means to foster cooperative in the investment portfolios of the National Iranian Oil Company to compete with foreign competitors during sanctions. By reviewing the results of the four scenarios derived from the game, it was observed that the rewards companies receive from sharing knowledge are dependent on the behavior resulting from knowledge sharing by other companies. The more capable an organization is in influential factors related to knowledge transfer and innovation; the more benefits companies will gain if they cooperate. Sensitivity analysis regarding the costs of project cooperative, which arises due to the difficulty of implementing joint projects, showed that as the costs increase, companies tend to shift from a cooperative strategy towards a retaliation strategy and then towards a non-cooperative strategy. The impact of companies' intellectual capital status on the selection of cooperative strategies was observed. Companies that decide to collaborate, if equipped with higher intellectual capital due to experience and empowerment, tend to prefer an optimal strategy towards cooperative. Manuscript profile
