【摘要】 经典的DEA模型视决策单元为黑匣子,不考虑内部结构.实际上,决策单元DMU可能具有各种各样的结构.对DMU进行效率评价时,尽管最初的输入和最终的输出相同,但考虑DMU结构与忽视DMU结构得到的效率不同.基于这样一种思想,提出了一种基于层次系统的DEA模型.更多还原

【Abstract】 The classic models of DEA regard DMU as a"dark box"and do not consider the internal structure.In fact,the DMU may have a variety of structures.When Considering the structure of DMU or ignoring it,we may get the different results,although DMUS have the same initial inputs and the same final outputs.Based on this thought,we establish one kind of hierarchy system DEA model.更多还原
