摘要
在分析传统 DEA模型局限性的基础上 ,探讨了 DEA模型最优解的不变性 ,证明了 C2 R模型在具有非正值输入输出指标下最优解的存在性。给出一个实例 ,说明该方法在对评价指标降维进而进行
Analyzing the limitations of traditional DAE model, this paper first presents the invariance of optimal solution in DEA model, then proves the existence of optimal solution for non positive evaluation index model in DEA. Finally, an illustrative example is provided for understanding the evaluation procedure.
