Abstract

Evaluating and studying efficiency is always one of the human needs to recognize its strengths and weaknesses points to have better efficiency by taking advantage of its strengths and covering its weaknesses. Efficiency evaluation has been converted into one of the fundamental concerns of organizations' managers in today's competitive conditions. Many researches have been conducted in this field due to the importance of evaluating and assessing organizations and people's efficiency, and researchers look at evaluation from different angles and present various methods for this purpose. To some extent, the window analysis method settles the observations' insufficiency problem in time evaluation by making the observation combination possible in time and cross-sectional series. So, four input indexes, including personnel, administrative, deposit, and overhead costs, and three output indexes, including deposit income, loan facility income, and fee income, were selected to assess banks' branches' efficiency using an interview with the experts and library study and subject literature review on order to evaluate bank branches' efficiency. Therefore, 45 bank branches were analyzed and evaluated according to the identified branches in the bank under study. In the conducted evaluation, the efficiency of 45 branches was firstly assessed using window cross-sectional data envelopment analysis, among which five branches were efficient. Branches' efficiency was first evaluated using the window CCR model to confirm the presented model, and then, they were ranked through the Anderson-Peterson method. The comparative results of intersecting efficiency and integration algorithm (super efficiency) were equal, and the model was confirmed.
