The Parameter Data Envelopment Analysis Model Based on C~2GS~2——PC~2GS~2
Hao Hai · Systems engineering and electronics · 2003
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.
