| 摘 要： | 提出了在模糊集上具有某种偏好的DEA,并通过Campos指数将模糊集之间的关系转化为一般的线性关系,建立了基于Campos指数的模糊DEA(FBCC-CI),据此测算决策单元的技术效率、模糊效率,识别决策单元的有效性,得到由不同偏好下的生产前沿面簇组成的模糊前沿,从直观上揭示了决策单元相对于生产前沿面的偏离不仅源于非有效,而且受非精确因素的影响.最后以简化的FBCC-CI为例,说明了该模型的有效性.

| Abstract: | This article proposes a DEA model with preference on fuzzy sets, and translates relation between fuzzy sets into the general linear relation through Campos index. Then a fuzzy DEA model based on Campos index (FBCC-CI) is put forward to measure the technological efficiency score and fuzzy efficiency score of each decision making unit (DMU), as well as to identify the efficient DMUs and to get fuzzy frontier constructed by a set of frontiers under different preference, which discloses explicitly that the derivation from the frontier is attributed not only to inefficiency but to the impact of imprecise factors. Finally, this model is proved valid by taking simplified FBCC-CI model as an example. |
