Abstract

The use of fuzzy sets in classical multiple criteria decision-making methods has led to forming fuzzy multiple criteria decision-making that enabled solving of a significantly larger number of decision-making problems. However, the membership function introduced in the fuzzy set theory has some limitations. Unlike the fuzzy set theory, intuitionistic fuzzy set theory also introduces the non-membership function. Therefore, intuitionistic fuzzy set theory, as an extension of fuzzy set theory, could provides some advantages in solving complex decision-making problems. WASPAS method is newly proposed, but widely used, multiple criteria decision-making method, for which numerous extensions have already been proposed. A new extension of WASPAS method, based on the use of single valued intuitionistic fuzzy sets and the Hamming distance proposed in this article. The efficiency and usability of the proposed approach are considered on the example website evaluation.
