| 摘 要： | 基于决策者的偏好结构和决策单元投入产出指标的概率分布，首次提出了一种新的随机数据包络分析模型－支配机会约束DEA模，给出了评价单元随机非支配DEA有效的定义和随机非支配DEA有效的必要条件，讨论了评价单元的投入、产出向量呈单因数对称随机分布时模型的确定性转换，并用算例说明了该随机DEA模型的应用前景和具体用法。

| Abstract: | A kind of dominance chance constrained DEA model is provided in this paper based on the DMUs' stochastic inputs/outputs and DM's preference structure. 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 dominance chance constrained DEA model has a promising use in practice. |
