DEA-efficiency evaluation model for simple network production systems
一类简单网络生产系统的DEA效率评价模型

Data Envelopment Analysis is an effective tool to measure the relative efficiencies of a group of DMUs.However,the traditional DEA models ignore the internal structures of DMUs,and overrate the DEA efficiencies of the evaluated systems.This paper sets up a DEA-efficiency evaluating model for one type of simple network production systems.The results show that the advanced model can do more to find inefficient DMUs and possible potential for performance improvement than the traditional approaches,and help dec...
