چكيده فارسي :
In traditional data envelopment analysis (DEA) models many decision making units (DMUs) are classified as efficient and a large number of methods for fully ranking both efficient and inefficient DMUs have been proposed. Cross-efficiency method is one of them. In cross-efficiencyranking methods, in addition efficiency value all units, also selection of weights are important. In this paper the weights of the cross-evaluationdetermined bylogical fuzzy, such as it is proportional with efficiencies. Therefore, it basically differs from previous methods.
