指标偏好DEA问题的研究及其应用

Research on the Construction and Effectiveness of Index Preference DEA Model

针对传统DEA模型对指标权重无任何限制的缺陷,首先构建了指标偏好DEA模型及对偶模型,并给出了指标偏好DEA模型的定义;然后研究了指标偏好DEA模型及其对偶模型的相关性质及有效性;最后通过实例验证了指标偏好DEA模型的合理性.

The traditional DEA model has no limitation on the index weight. To solve this problem,first the in-dex preference DEA model and the dual model are constructed,and the definition of index preference DEAmodel is given;then the relative properties and effectiveness of the index preference DEA model and its dualmodel are studied;finally,the rationality of index preference DEA model is verified by an example.
