摘　　要：在应用DEA方法进行绩效评价的过程中,多个决策单元同为DEA有效而无法区分相对优劣的情况经常出现。为了对决策单元进行全排序,本文揭示了潜力损失和强弱有效性之间的内在关联,定义了虚拟决策单元的概念,并提出一个基于虚拟决策单元的全排序方法,来判定DEA有效的决策单元的优劣。最后我们用一个实例来说明本方法的计算过程。In the evaluation process by applying DEA method,it often runs into the case that more than one Decision Making Units (DMUs) are efficient simultaneously and can not be discriminated completely.The essential relationships between the potential loss and the strong - week efficiency are carefully investigated,as well as the concept of Virtual Decision - Making Unit(VDMU) is defined,and then a new fully ranking method for DMUs based on VDMU is proposed.Finally,an example is used to demonstrate the iterative and practicability of the new method.
