Study on sample data envelopment analysis method with restrain cone
Zhanxin Ma · Systems engineering and electronics · 2007
To solve the problem that data envelopment analysis(DEA) methods can not provide evaluating information by a determinate frontier,a new sample DEA method with restrain cone(PSam-C2WH) is provided by using some sample units.At the same time,the definitions of SCDEA-efficiency and weak-SCDEA-efficiency are developed.The relationships between(PSam-C2WH) and other evaluation models are discussed.In addition,the relationship between SCDEA-efficiency and the relevant multiple objective programming pareto effective solution is studied.Finally,the properties on projection and distribution of decision making units are studied,and the meaning of SCDEA-efficiency and weak-SCDEA-efficiency are explained.
