This paper deals with the problem of efficiency assessment using Data Envelopment Analysis (DEA) when the input and output data are given as fuzzy sets. In particular, a fuzzy extension of the measure of inefficiency proportions, a well-known slacks-based additive inefficiency measure, is considered. The proposed approach also provides fuzzy input and output targets. Computational experiences and comparison with other fuzzy DEA approaches are reported.

基于模糊DEA松弛的方法

当输入和输出数据为模糊集时，本文使用数据包络分析（DEA）解决效率评估问题。特别地，考虑了效率低下的度量的模糊扩展，这是众所周知的基于松弛的加性效率低下的度量。所提出的方法还提供了模糊的输入和输出目标。报告了计算经验并与其他模糊DEA方法进行了比较。
