Abstract

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. The study aims to describe the methodology and findings of a survey to assess the effectiveness of DEA models in estimating input/output levels, incorporating managerial preferences, and improving efficiency over time.
Methodology: This paper reviews DEA models for estimating input/output levels, applying manager or decision-maker preferences, and improving inefficient units over a while. Finally, we have implemented the models obtained in 24 supervisory branches with four input indicators and four indicators in one of the banks, and the results have been presented and interpreted.
Findings: The results show that management can increase the index of attracting new customers in proportion to the collection's ability in the input indicators.
Originality/Value: The problem was implemented in the unit under the second evaluation and showed different results in different cases, although this is important for all units under assessment.
