Abstract:

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 is both a valid and an efficient one. Since most of proposed models do not provide the projection of Pareto efficiency, a model is developed and presented through this paper based on which in addition to calculating the amount of super efficiency, the projection of Pareto efficient is obtained. Moreover, the model is unit invariant, always feasible and makes the amount of inefficiency effective in ranking.
