基于样本前沿面的多准则评价模型的有效性

Efficiency of a Multiple Criteria Evaluation Model Based on Some Sample Units

从样本评价模型的基本思想出发,根据SDEA(d)有效决策单元是否位于样本前沿面上将其分为强SDEA(d)有效和真SDEA(d)有效,从而可以提供更多的有效决策单元和样本单元比较的综合信息;其次,在基于样本前沿面的投入型评价模型基础上提出了同时面向输入和输出的多准则评价模型,并对该模型的有效性理论,相对效率评价指数和投影分析作了进一步探讨;最后通过实例表明了基于样本前沿面的多准则评价模型的优越性.

According to SDEA（d） efficient decision making units（DMU） whether or not on the frontier that formed by some sample units,the SDEA （d） efficient DMUs can be divided into strong SDEA （d） efficient and proper SDEA （d） efficient, it can provide more information about the SDEA（d） efficient DMUs compared with sample units. Secondly, based on the input Sam-Eva model,a multiple criteria Sam-Eva model input and output orientation is proposed,moreover,some further research in its efficiency theorems, relative efficiency evaluation indexes, and projection analysis is done. Finally, the superiorily of the multiple criteria evaluation model based on some sample units is proved by an example.
