Abstract

Methods of multi-criteria decision-making (MCDM) TOPSIS and VIKOR developed using intuitionistic fuzzy sets are revised and discussed. Thus, some modiļ¬cations of these methods are given. New intuitionistic fuzzy similarity and a distance measures are proposed. Some remarks are introduced for use of similarity measure instead of distance measure in VIKOR and TOPSIS. Therefore, an illustrative example using TOPSIS and VIKOR and comparing results of new similarity and distance measures with some measures from literature is presented.
