| 摘 要： | 在模糊DEA模型的基础上,引入模糊数的加权平均值,建立了一个可以体现决策者风险偏好的模糊DEA模型.通过对此模型的求解可以实现决策者在不同乐观程度下对决策单元的评价.最后,通过对几家超市的效率评价的实例分析,验证了该模型的优越性.

| Abstract: | Based on the fuzzy DEA model,the article proposes a DEA model with decision-maker's risk preference by introducing the weighted average of the fuzzy number.The decision making unit can be evaluated under varying optimistic degrees of the decision-maker by solving the problems of this DEA model.Finally,an example is given,in which the efficiency of several supermarkets is evaluated with this model,to prove its superiority. |
