EvaluatingEfficiency off Decision Making Units with Stochastic Data: A Stochastic Common Weight Data Envelopment Analysis

In this paper a stochastic common weight data envelopment analysis (SCWDEA) is proposed for evaluating efficiency of different decision making units (DMUs). Furthermore in some situations full ranking may not be acquired. Thus, SCWDEA is developed to discriminate entities which their composite indicator is 1. In order to show the capability and applicability of the proposed SCWDEA model, an example is taken from the literature and the results are compared in term of efficiency scores. Discrimination power of the proposed model is shown among entities which receive composite index of 1.
