Fuzzy analytic hierarchy process with interval type-2 fuzzy sets
TLDR
The objective is to develop an interval type-2 fuzzy AHP method together with a new ranking method for type- 2 fuzzy sets that applies the proposed method to a supplier selection problem.Abstract:
The membership functions of type-1 fuzzy sets have no uncertainty associated with it. While excessive arithmetic operations are needed with type-2 fuzzy sets with respect to type-1's, type-2 fuzzy sets generalize type-1 fuzzy sets and systems so that more uncertainty for defining membership functions can be handled. A type-2 fuzzy set lets us incorporate the uncertainty of membership functions into the fuzzy set theory. Some fuzzy multicriteria methods have recently been extended by using type-2 fuzzy sets. Analytic Hierarchy Process (AHP) is a widely used multicriteria method that can take into account various and conflicting criteria at the same time. Our objective is to develop an interval type-2 fuzzy AHP method together with a new ranking method for type-2 fuzzy sets. We apply the proposed method to a supplier selection problem.read more

A novel spherical fuzzy analytic hierarchy process and its renewable energy application
TL;DR: The aim is to extend classical analytic hierarchy process (AHP) to spherical fuzzy AHP (SF-AHP), and to show its applicability and validity through a renewable energy location selection example and a comparative analysis between neutrosophic AHP and SF-A HP.

Multi-criteria evaluation of green suppliers using an extended WASPAS method with interval type-2 fuzzy sets
TL;DR: A new integrated approach based on Weighted Aggregated Sum Product Assessment (WASPAS) method, is proposed to deal with multi-criteria group decision-making problems with IT2FSs, and it is shown that combining the subjective and objective weights can help to increase the stability of the proposed approach with different weights of criteria.

Prioritization of renewable energy alternatives by using an integrated fuzzy MCDM model: A real case application for Turkey
Murat Çolak,İhsan Kaya +1 more
TL;DR: A MCDM methodology based on type-2 fuzzy sets whose membership functions are also fuzzy and hesitant fuzzy sets that enable to handle situations that an element has several membership value are more able to model uncertainties in decision making process are suggested to evaluate renewable energy alternatives for Turkey.
