【摘要】 数据包络分析是系统工程的一种重要方法 ,特别适宜处理多输入、多输出的复杂系统的评价问题。在数据包络分析C2 GS2 模型的基础上 ,通过对评估决策单元的输入进行调整 ,得出了一个带有参数的C2 GS2 ———PC2 GS2 模型。探讨了模型的有关性质 ,给出了阈值的概念 ,并通过理论分析和实例验证 ,说明阈值能更好地描述决策单元的相对信息更多还原

【Abstract】 The data envelopment analysis is an important measuring method for system engineering and particularly suitable for dealing with the multi-input and multi-output evaluation problems of a complex system. The parameter data envelopment analysis model based on C+2GS+2 is established by adjusting the inputs of the evaluated decision making unit in this paper. The property of the PC+2GS+2 model is verified and the concept of the threshold is put forward. Moreover, through the theoretical analysis and application, it is demonstrated that more information related to the evaluated decision making unit can be revealed by the threshold.更多还原
