摘要
在评价指标可取负值及较宽松的条件下论证了有关C2R模型(D)及扩展的C2R模型(D0)的最优解存在性定理.然后,在输出可取负值的情况下,给出了用(D0)来判断DEA有效的定理,并据此讨论了评价指标有相对误差时的灵敏度分析.
This paper demonstrates the theorems on the existence of optimal solution for C^2R model (D) and extensive C^2R model (D_0) under broader conditions, in which evaluation indexes may take negative value. Then, when output may take negative value, this paper gives a theorem on discriminating DEA efficiency with model (D_0), and on the basis of this theorem presents some theorems on sensitivity analysis as the value of each evaluation index has relative error.
