摘要
为了克服决策单元在有效性的评价和排序方面占主导地位的缺陷,在扩展DEA模型的基础上,对于输出减少时的逆DEA问题进行了讨论.通过求解相应的多目标规划问题(VP),得到了多目标规划(VP)的Pareto弱有效解与评价减少了输出的决策单元的规划问题的最优值之间的一些相关性质.对于决策单元为弱DEA有效的情形,也进行了类似的讨论.最后用数值实例加以说明.
In order to overcome the dominant positional faults of the assessed DMU in DEA models in evaluating efficiency and ranking DMUs, based on the extended DEA model, the problem of inverse DEA with reducing of output is discussed. By solving the relevant multi-object programming （VP）, some correlative qualities between the weak Pareto efficient solution of （VP） and the optimal value of the programming evaluating the DMU with reducing of output are obtained. The similar discussion is done for the DMU which is weak DEA efficient. Some examples are illustrated.
