A Generalized Value Efficiency Model for Data Envelopment Analysis
Sun Yong-he · Zhongguo guanli kexue · 2005
Aiming at overcoming the drawback of unreasonable weight flexibility in Data Envelopment Analysis(DEA),this paper presents an Applicable Generalized Value Efficiency Model(AGVEM)for DEA to measure the value efficiency of decision-making units(DMU).The AGVEM is for cases in which the decision-maker's preference functions on outputs are nonlinear.The model is given by way of generalizing the basic theorem of DEA to accommodate value preference estimates on DMU's outputs,through which weight assurance regions for DEA value efficiency analysis could scientifically and reasonably be introduced using the principle of multiple criteria decision making.A data experiment for verifying the AGVEM shows that the model is able to produce more reliable and powerful conclusions on DMU-discrimination.
