【Abstract】 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.更多还原
