对超效率综合DEA模型,有三个定理来判断其不可行性,其中一个定理基于加性模型来判断,并证明:当模型不可行时被评决策单元的扩展DEA有效性,由此给出了对扩展DEA有效的决策单元排序的方法,此外,对不含非阿基米德无穷小的基于输入(输出)的超效率综合DEA模型,当其最优值为1时,有一个定理来判断被评单元的DEA有效性.
There are three theorems to determine the infeasibility of the super efficient integrated DEA model. One of the theorems is judged based on the additive model, and it is proved that the extended DEA of the decision-making unit is validated when the model is not feasible, In addition, for non-non-non-Archimedes infinite input-output-based super-efficiency integrated DEA model, when there is an optimal value of 1, there is a theorem to judge whether a Assessing the DEA Validity of a Unit.
