Continuous Intuitionistic Fuzzy CRITIC & WASPAS: Smart City Evaluation

Continuous intuitionistic fuzzy sets (CINFUSs) have been introduced by Alkan and Kahraman (2023). CINFUSs overcome some of the limitations of intuitionistic fuzzy sets and provide a continuous model of discrete intuitionistic fuzzy sets. The degrees of membership and non-membership are taken into account as a continuous function in CINFUSs. Thus, membership and non-membership degrees provide a continuous structure which changes with respect to decision maker’s behavior against uncertainty. We extend CRITIC method to CINFU CRITIC method to determine the weights of the considered criteria. Then, we also extend WASPAS method to CINFU WASPAS to compute the performance scores of the alternatives. We compare CINFU CRITIC & WASPAS methodology with an existing methodology to validate our proposal. We present an MCDM application to smart city evaluation.
