Interval-Valued Intuitionistic Fuzzy TODIM

The TODIM (an acronym in Portuguese for Interative Multi-criteria Decision Making) method has recently been extended firstly to fuzzy and next to intuitionistic fuzzy environments with promising results. In this paper, we further consider the extension of TODIM to interval-valued intuitionistic fuzzy (IVIF) environments. Two case studies are used to illustrate the approach to multi-criteria decision making. Experimental results show the effectiveness of the presented method. (C) 2014 Published by Elsevier B.V.
