摘要
本文对数据包络分析方法的有效决策单元作了灵敏度分析。文中首先提出一种只考虑乎一投入量变化时的灵敏度分析方法,然后在此基础上研究几个报入量同时变化时的灵敏度分析。进而扩展到产出量变化投入产出量同时变化时的灵敏度分析,最后用数例进行了说明。
This paper deals with the sensitivity analysis of efficient decision making units in Data Envelopment Analysis Method. First, the authors present a model which can be used when only single input variable is changing; then, a method suitable for the sensitivity analysis when several input variables are changing simultaneouslyis. Finally, the method is extended to the changes of output variables as well as the changes of output and input variables at the same time. The results are presented in the form of a numerical example.
