Evaluation of Bank Branch Performance using Data mining and Expert System Approach

Branches of Bank are one of the most important pillars of digital banking and surveying their performance plays an important role in profitability and achieving the bank's goals. This study evaluates the performance of bank branches using innovative methods. First, important indicators for evaluating branch performance have been identified. Then, the proposed method for data of bank branches has been implemented in the form of a case study. For this purpose, clustering was done first to separate efficient, semi-efficient and inefficient branches. Then, based on the labels created on the data of the branches, classification algorithms and decision trees were used to extract the rules in the data of efficient, inefficient and semi-efficient branches. In the present study, the proposed model of C5.0 algorithm was used due to obtaining the highest accuracy compared to other algorithms. Finally, based on the extracted rules, an expert system was designed to evaluate the performance of bank branches. Clips software was used to design the expert system. In the bank under study, the average increase percentage of cheap deposits during the period to increase the target balance had the greatest impact on performance.
