Article
Traditionally, data envelopment analysis (DEA) requires all decision-making units (DMUs) to have similar characteristics and experiences within the same external conditions. In many cases, this assumption fails to hold, and thus, difficulties will be encountered to some extent when measuring efficiency with a standard DEA model. Ideally, the perfor...

The ranking of decision-making units (DMUs) is one of the most significant issues in efficiency evaluation. However, the calculation results from the traditional DEA method sometimes include multiple efficient DMUs or multiple DMUs with the same efficiency value, in which case the approach is weak in distinguishing among these DMUs. Therefore, this...

Data envelopment analysis (DEA) method based on game theory effectively ranks the decision-making units (DMUs) by the view of cooperation or competition. The DEA method based on partial ordered set theory depicts the relationships among DMUs. However, these methods are unable to reveal the complex cooperation and competition relationships among DMU...

When we evaluate the efficiency by applying data envelopment analysis (DEA), it is necessary that all of the indexes must have a preference, that is, the bigger the better or the smaller the better. However, when the neutral indicator is among the evaluation index system, the traditional DEA methods will unable to solve such issues. Therefore, base...

There exist two problems that need to be solved on the efficient measure of generalized data eve-lopment analysis (DEA). Firstly, when the generalized DEA model is infeasible, the efficiency of the decision making unit cannot be expressed by detailed figures although it is efficient. Then, when decision making units are generalized DEA efficient, t...

Traditional DEA is an evaluation method based on the self-assessment system; the decision-makers cannot choose a frame of reference freely. In order to solve the DEA method can be based on both self-assessment system and any frame of reference for evaluation, the generalized output-oriented DEA model based on BC2 is given in this paper. Then throug...

It's more reliable on the decision-making units when the reference set is chosen by t raditional DEA cross-efficiency evaluation method, so decision-makers can’t select the proper reference system for evaluation. Therefore, we give a new cross-efficiency evaluation method based on sample units in this paper. Furthermore, we also propose a generaliz...
