| 摘 要： | 在输入、输出数据为模糊数而效率值为准确值的模糊DEA模型中,会出现有两个以上有效单元,从而无法对所有决策单元进行全排序的情形。本文利用模糊数的基于α-截集的比较规则,建立了模糊条件下的超效率DEA模型,有效地解决了模糊决策单元的全排序问题。文末给出了一个实例。

| Abstract: | In the fuzzy DEA model whose inputs and outputs are fuzzy and efficiency score is precise,all DMUs could not be ranked when the number of efficient units is no less than two.To that end,we devel op a fuzzy super-efficiency DEA model by using a ranking method based on the comparison of α-cuts,our approach can be seen as an extension of the super-efficiency DEA model that can fully rank fuzzy DMUs.In the end,an empirical example is illustrated. |
