摘要
在广义DEA模型基础上,建立基于LR模糊数的广义模糊DEA模型.通过引入LR模糊数的加权平均值,计算了待评价决策单元能体现决策者偏好的广义模糊效率和平均广义模糊效率,对待评价决策单元进行有效性排序.最后通过实例分析,表明了该模型的实用性.
Based on generalized DEA, this paper proposes generalized fuzzy DEA with LR-type fuzzy number. Through the weighted average value of LR-type fuzzy number, this paper calculates generalized fuzzy efficiency with preference of decision- makers and average generalized fuzzy efficiency on decision making unit, solves the ranking for fuzzy decision making unit. Finally, an example is offered to demonstrate the practicality of generalized fuzzy DEA with LR-type fuzzy number.
