Cross-efficiency evaluation has been suggested as an alternative method of efficiency evaluation and ranking in Data Envelopment Analysis (DEA) based on peer evaluation logic. A factor that possibly reduces the usefulness of the cross-efficiency evaluation is that cross-efficiency scores may not be unique due to the presence of alternative optima. As a result, it is recommended that secondary g...

the cross efficiency evaluation is used to performance measurement of decision making units in data envelopment analysis concept. one of the most important shortcoming of this method is existing alternative optimal solution and therefore, the efficiency scores are not unique. we are going to summarize the pervious models proposed by researchers and suggest an alternative secondary goal approach...
