Computational and theoretical pitfalls in some current performance measurement techniques; and a new approach

This paper addresses some pitfalls of some fuzzy data envelopment analysis models which have been provided in recent published papers. This study deals with these papers from both computational and theoretical points of view. Moreover, a new approach to deal with fuzzy data in DEA framework is provided, which does not have the mentioned pitfalls
