摘要
通过对DEA有效单元排序中超有效性方法的探讨,提出了一种新的方法.利用对构造模型目标函数的处理,新的方法能够实现对有效单元的完全排序.最后,通过两个算例进一步验证了新方法的可行性和优越性.
In this paper, we pursue "super-efficiency" issue for ranking efficient units in DEA (data envelopment analysis) and propose a new approach. Efficient DMUs (decision making units) can be ranked completely by processing the objective function of construction models. In the end, we provide two numerical examples to examine our method, it has feasibility and advantage.
