Purpose: In this study, the strategies of internal and external decision-makers in Borjam are examined using game theory.Methodology: The decisions made by three related personalities in JCPOA, including the leadership of Iran, the Government of Iran, and the group (1 + 5), were simulated using game theory and analyzed based on the game theory mechanism. In the problem statement section, principles are accepted, and the game is designed based on them. The AHP method was used to evaluate the consequences of the game. The low incompatibility rate calculated for this method describes the evaluation results as acceptable. Entering the negotiations in a static game is expressed with complete information, and the mutual agreement process is shown as a dynamic game.Findings: The game is discussed from two aspects. The pre-game section examines the nature of entering or not entering the negotiations. Examining the game process shows that entering negotiations is strategic for Iran and the group (5 + 1). However, in the main game, strategies for decision-making are examined. Trust without guarantee has been shown to change the game's outcome from win-win to win-lose.Originality/Value: There are various attitudes about JCPOA. In this research, regardless of attitudes and factions, the work process is implemented in a scientific model with a strategic structure.

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.
