摘要:

运用传统方法对区间DEA中的决策单元(DMU)进行排序时,会出现区间DEA有效的DMU具有相 同效率值的情况,因此无法对所有DMU进行完全排序。借鉴效率值判别分析(DR)方法对区 间DEA中DMU的排序方法进行了改进,形成了区间DR/DEA方法,通过利用该方法求得的因DMU 不同而各不相同的效率值,达到了对区间DEA中所有DMU进行完全排序的目的,最后给出了一个算例

关键词: 区间DEA, 决策单元, 排序, 效率值判别分析

Abstract:

The traditional approaches could not fully rank all the DMUs in interval DEA because the efficient DMUs have the same efficiency scores. In order to solve this problem, we combined the discriminant analysis of ratios (DR) method with interval DEA so as to establish a new approach: the interval DR/DEA method. The efficiency scores provided by this method is different from one DMU to another, therefore they can be used to fully rank all the DMUs in interval DEA. This method is demonstrated through an example in the end. 

Key words: interval DEA, DMU, ranking, discriminant analysis of ratios
