Calculation of efficiency and efficiency of branches of National Bank of West Tehran

The bank is an economic entity that carries out the tasks of equipping and distributing credit, financial operations, currency trading, documentary and dividend claims, stock maintenance and securities. The National Bank of Iran has a staff of over 45,000 people. The National Bank has 5 branches operating in Iran, 2 operating branches and 2 subsidiaries abroad. Branches and Evaluate Branch Productivity during 96 and 97 Years Using Data Envelopment Analysis (DEA) Model. For this purpose, the effective factors are first evaluated and then the DEA model is used to evaluate the performance of the branches in order to measure their efficiency and inefficiency. We then rank them using the AP model and finally measure the productivity of a branch relative to 96 and 97 using the Malmquist Productivity Coefficient model. In this paper, using the data analysis approach, the performance of the West Bank Branches of Tehran National Bank in two years has been evaluated. The efficient and inefficient units of this branch are then identified by the CCR model and finally the efficient branches are ranked with the Anderson Peterson (AP) model and finally the Malmquist efficiency model is measured.
