摘要
文章对数据包络分析(DEA)的强有效性问题提出了一种新的研究方法.利用有效值和负有效值来构造复合输入和输出这种方法可以实现有效决策单元的完全排序.文章还给出了新方法中模型的一些性质.最后,用两个例子来检验此方法并和其他模型的计算结果进行了比较.
This paper pursues “super-efficiency” issue in DEA (data envelopment analysis) and proposes a new approach. By using efficiency and anti-efficiency scores to make up compound inputs and outputs,efficient DMUs (decision making units) can be ranked completely. Some characteristics of our models are proposed. Applying this approach,the paper examines two numerical examples and compares the results with some traditional methods.
