本文给出了一种新的决策单元排序方法。基于经典的C2 R模型,通过引入一个虚拟的决策单元,形成了一个新的排序模型,按照相对效率值的大小实现了决策单元的排序。实验表明,新排序方法不仅能较好地反映C2 R模型的计算结果,而且可避免超效率方法造成的相对效率值偏大的弊端。新的排序方法依据充分、简单方便,同时体现了整体的决策效率。
本文給齣瞭一種新的決策單元排序方法。基于經典的C2 R模型,通過引入一箇虛擬的決策單元,形成瞭一箇新的排序模型,按照相對效率值的大小實現瞭決策單元的排序。實驗錶明,新排序方法不僅能較好地反映C2 R模型的計算結果,而且可避免超效率方法造成的相對效率值偏大的弊耑。新的排序方法依據充分、簡單方便,同時體現瞭整體的決策效率。

In the paper, a ranking method is presented for decision-making units.Based on the classical C2 R model, a new ranking model is obtained by introducing a virtual decision-making.According to the value of rela-tive efficiency, all decision-making units can be ranked.Experiments show that the ranking method can reflect the computational result of C2 R model better.Moreover,it can’ t make the value of relative efficiency too large like the super-efficiency method.Not only does the method provide a sufficient basis, but it is very simple.It is deserved to note that it has embodied the systemic efficiency.
