Common set of weights in DEA-R models

This paper uses the common set of weights (CSW) method to control the total weightflexibility in the DEA-R and proposes a CSW DEA-R method. In the evaluations of DMUs byCSW DEA-R method each input and output ratio takes the same weight in all DMUs. Theproposed CSW DEA-R method improves the discrimination power of the DEA-R method. Then,we compare the CSW DEA-R method with the DEA-R and DEA approaches in the literature; anddemonstrate the applicability of the proposed method with an empirical example.
