Abstract:
In this paper, common set of weights (CSWs) method is modified by means of super-efficiency idea so that it would be able for ranking DMUs, completely. The CSWs method, as an idea for ranking the efficient units, is encountered with more than one unit with efficiency score one (CSWs-efficient), so it could not be considered as a ranking method. But, based on its different nature in relation to classic DEA that appropriates same value to the same index of differentDMUs can be considered as a method to evaluate the performance of DMUs. Thus in this study, based on super-efficiency idea, we extend CSWs method to rank the CSWs-efficient units. Finally, a numerical example is provided to illustrate the method.
