Cross-efficiency Evaluation under the Principle of Rank Priority of DMUs
نویسندگان
چکیده
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 goals should be introduced in cross-efficiency evaluation. This paper seeks to improve the secondary goal proposed by Wu et al. (2009) [Determination of cross efficiency under the principle of rank priority in cross evaluation, Expert Systems with Applications, 36, 4826-4829], by introducing a Mixed Integer Linear Problem (MILP) as secondary objective function. Numerical example is provided to illustrate the model.

Obtaining a Unique Solution for the Cross Efficiency by Using the Lexicographic method
Cross efficiency is a method with the idea of peer evaluation instead of self-evaluation, and is used for evaluation and ranking Decision Making Units (DMUs) in Data Envelopment Analysis (DEA). Unlike most existing DEA ranking models which can only rank a subset of DMUs, for example non-efficient or extreme efficient DMUs, cross efficiency can rank all DMUs, even non-extreme ones. However, sinc...
متن کاملCross-efficiency evaluation by the use of ideal and anti-ideal virtual DMUs’ assessment in DEA
To rank Decision Making Units (DMU) in Data Envelopment Analysis (DEA), the peer-evaluation based cross-efficiency method is generally used. Indeed, in this method, each DMU is evaluated from the view point of other DMUs. In this article, a method is suggested which instead examines each DMU just by using the weights resulting from the evaluation of ideal and anti-ideal virtual DMUs and thus ex...
متن کاملInterval Efficiency Assessment in Network Structure Based on Cross –Efficiency
As we know, in evaluating of DMUs some of them might be efficient, so ranking of them have a high significant. One of the ranking methods is cross-efficiency. Cross efficiency evaluation in data envelopment analysis (DEA) is a commonly used skill for ranking decision making units (DMUs). Since, many studies ignore the intra-organizational communication and consider DMUs as a black box. For sign...
متن کاملA New Goal programming approach for cross efficiency evaluation
Cross efficiency evaluation was developed as an extension of DEA. But the traditional DEA models usually have alternative optimal solutions and, as a result, cross efficiency scores may not be unique. It is recommended that without changing the DEA efficiency scores, the secondary goal should be introduced for optimization of the inputs/outputs weights. Several reports evaluated the perfo...
متن کاملRanking of units by anti-ideal DMU with common weights
Data envelopment analysis (DEA) is a powerful technique for performance evaluation of decision making units (DMUs). One of the main objectives that is followed in performance evaluation is discriminating among efficient DMUs to provide a complete ranking of DMUs. DEA successfully divides them into two categories: efficient DMUs and inefficient DMUs. The DMUs in the efficient category have ident...
