摘要
设有n 个决策单元,每个有m 个输入及s个输出,其中某些输入或输出可以取负值。此外,被评价的决策单元可以不是上述n 个之一。在这种情况下,分别给出了有关C2R模型与C2GS2 模型存在最优解的必要条件或充分条件。
Suppose that there are n decission making units (DMUs) with m inputs and S outputs,where some inputs or outputs may be negative.In additiion,an evaluated DMU may be not one of above n DMUs.In such a case, this paper presents the sufficient conditions or necessary conditions on the existence of optimal solution for C 2R model and C 2GS 2 model respectively.
