A single-stage approach for selecting inputs/outputs in DEA

Popis výsledku v původním jazyce

Data Envelopment Analysis (DEA) is an optimization-based methodology to evaluate the performance of Decision Making Units (DMUs), each one consumes multiple inputs to produce multiple outputs. From the statistical and empirical points of view, if the number of inputs/outputs is high in comparison with the number of DMUs, then a large percentage of DMUs will be identified as efficient and efficiency discrimination among DMUs is questionable. It also implies that the selection of rel-evant inputs/outputs is very crucial for successful theoretical and applied purposes. In order to deal with selective input/output measures in DEA, some two-stage ap-proaches are proposed where selective measures are chosen in the first stage and then the DMUs are evaluated in the second stage based on the selected measures. The cur-rent study suggests a common weights DEA model which selects inputs/outputs as well finds the efficiency of DMUs in a single-stage approach. An illustrative example of the banking industry in Iran is provided to validate the proposed approach. Obtained Results emphasize that the suggested approach correctly deals with selective measures.
