| 摘 要： | 为了判断决策单元是否(弱)DEA有效并克服现有的模型及[1]中模型在解决上述问题时的不足之处,本文将讨论的新模型是由CCR模型与CCGSS模型变来的,且定理的证明不同于[1]．还讨论了文中新模型的最优解的存在性,此外,研究了所有决策单元的输入输出的变化对某决策单元有效性的影响．

| Abstract: | To Discriminate whether a decision making unit (DMU) is (weak) DEA efficient and to overcome some drawbacks for the existing models and the model in [1] solving above problem, this paper discusses to a new model coming from both CCGSS model and CCR model with demonstration of theorems different from [1]. For new model in this paper, the existence on its optimal solution is discussed yet. Besides the effect of variation of inputs and outputs of all DMUs on efficiency of a DMU is studied. |
