The Study of Stochastic DEA Model and Its Application
随机DEA模型及其应用

A kind of stochastic DEA model is provided in this paper based on the DMUs' stochastic inputs/outputs. The stochastic DEA efficiency of DMU is defined and the necessary conditions for efficiency evaluation are discussed. With the single random factor assumption, the stochastic DEA problems can be solved via the method of chance constrained programming and the goal programming theory. Finally, a case is given to point out that stochastic DEA model has a promising use in practice.
