Purpose: 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.
Methodology: 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.
Findings: 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.
