Abstract

In a recent paper in this journal by Liu [Shiang-Tai Liu. (2008). A fuzzy DEA/AR approach to the selection of flexible manufacturing system. Computer &Industrial Engineering, 54, 66-76], he provided conditions to find lower and upper bounds of the @a-cut of E~"r and then, by these conditions, he introduced two models. In this paper we correct the proof of his theorem and also, we correct the presented models for finding lower and upper bounds of the @a-cut of E~"r.
