Abstract
Type 2 Intuitionistic sets (IFS2) have been introduced by Atanassov (1999). They let experts assign membership and nonmembersip degrees in a wider area than it is in ordinary intuitionistic fuzzy sets. In this paper, we employ IFS2 sets for the development of IFS2 WASPAS method. WASPAS is a multicriteria method integrating simple additive weighting and weighted product methods. Single valued IFS2 sets have been used in the IFS2 WASPAS method. We illustrate the application of the proposed IFS2 WASPAS through a selection problem among communication firms.
