Calculating Super Efficiency of DMUs for Ranking Units in Data Envelopment Analysis Based on SBM Model

Abstract EN

There are a number of methods for ranking decision making units (DMUs), among which calculating super efficiency and then ranking the units based on the obtained amount of super efficiency are both valid and efficient.

Since most of the proposed models do not provide the projection of Pareto efficiency, a model is developed and presented through this paper based on which in the projection of Pareto-efficient is obtained, in addition to calculating the amount of super efficiency.

Moreover, the model is unit invariant, and is always feasible and makes the amount of inefficiency effective in ranking.
