| 摘 要： | 本文给出了一种新的决策单元排序方法。基于经典的C2R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C2R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。

| Abstract: | In the paper, a ranking method is presented for decision-making units. Based on the classical C2R model, a new ranking model is obtained by introducing a virtual decision-making. According to the value of relative efficiency, all decision-making units can be ranked. Experiments show that the ranking method can reflect the computational result of C2R 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. |
