...arrell(1957)提出,后来由Charnes、Cooper和Rhodes(1978)扩展得到基本的CCR模型,用来评价决策单元(Decision Making Unit-DMU)的相对效率(Relative Efficiency),该方法通过线性规划构造一个前沿面,再将决策单元与此前沿面进行对比,得到各单元的相对效率...
ThepreferenceDEAmodel is put forwardbasedon the traditional DEA model to solve the comprehensiveevaluation, and to solve the sameefficientDMUwiththe averagecross-efficiency.
