Bank data set

This dataset contains information on 60 bank branches, which were used as Decision Making Units (DMUs) in the application of Data Envelopment Analysis (DEA). The dataset includes input and output variables relevant to branch-level efficiency evaluation. These variables were collected from internal banking records and prepared in a structured format suitable for DEA modeling. The purpose of this dataset is to provide a benchmark for evaluating branch efficiency and to support reproducibility of the experiments presented in the associated research manuscript. All branch identifiers were anonymized to ensure confidentiality, while preserving the integrity of the efficiency analysis.
