Abstract :

One way to rank DMUs in DEA is the cross efficiency method. In this method, the efficiencyof each DMU is calculated by other DMUs optimum weights, which makes the ranking moreacceptable for managers. Existing alternative optimum weights in cross efficiency methodlead to several ranks for DMUs. Several secondary goals have introduced to avoid thisproblem, till now. In this paper, a new model is presented, that would be satisfying andacceptable for all DMUs. Therefore, by solving this model, the optimum weights areagreeable and fairy for DMUs.
