随机DMU相对有效性评价的期望值方法及其应用

The expected value approach and its application in the relative efficiency evaluation of stochastic DMU

DEA的随机性研究是目前 DEA理论研究的前沿。本文基于随机条件下决策单元期望有效性指数的概念 ,提出了随机 DMU相对有效性评价的期望值方法 ,给出了随机 DMU相对有效的两个定义 。

This paper firstly extends the efficiency measurement to deal with random inputs and outputs by computing the “expected” efficiency score for individual DMUs. Two kind of definition of the relative efficiency of random DMUs, based on their “expected” efficiency score are given and the calculation of the expected efficiency scores is discussed in the paper.
