Study on Rank Analysis of Efficient Decision Making Unit with Data Envelopment Analysis - with Application to Commercial Banks -
DEA have been used to evaluate the performances of decision making units (DMUs). And in most models of DEA, the best performers have efficient status denoted by unity(100%). But we can find that usually plural DMUs have this efficient status. Super-efficiency models make it possible to discriminate between these efficient DMUs and rank them. The rationality for these measures is to minimize a sort of weighted distance from an efficient DMU to the production possibility set excluding the DMU. Therefore, the super-efficient scores can be greater than 1, and the DMU with the highest score is the best performer compared with other DMUs. When specialized in input/output orientation, super-efficiency measure based input/output slacks(Super-SBM) can be directly compared with Super-CCR radial expansion/reduction of input/output. This study applied these two models to measure super-efficiency scores of 13 commercial banks and ranked them.
