International Journal of the Analytic Hierarchy Process

A Special Issue on

AHP Variants Based on Extensions of Ordinary Fuzzy Sets

Guest-edited by Prof. Cengiz Kahraman


Aim of the issue

The aim of this issue is to gather the theoretical and practical studies on fuzzy Analytic Hierarchy Process (AHP) and fuzzy Analytic Network Process (ANP), developing new variants or using the existing fuzzy variants in innovative application areas.

Fuzzy sets have a history starting from ordinary fuzzy sets and extending to other types of fuzzy sets: Ordinary fuzzy sets (Zadeh, 1965), interval-valued fuzzy sets (Zadeh, 1975; Grattan-Guiness, 1975; Jahn, 1975; Sambuc, 1975), type-2 fuzzy sets (Zadeh, 1975), intuitionistic fuzzy sets (Atanassov, 1986), fuzzy multisets (Yager, 1996), neutrosophic sets (Smandarache, 1999), nonstationary fuzzy sets (Garibaldi and Ozen, 2007), Hesitant fuzzy sets (Torra, 2010), and Pythagorean fuzzy sets (Yager, 2013). Each of these extensions has been extensively used in the solutions of decision making problems. Ordinary fuzzy sets, intuitionistic fuzzy sets and hesitant fuzzy sets are the most used extensions in the fuzzy sets history, respectively.

Analytic Hierarchy Process (AHP) and Analytic Network Process (ANP) are the most used multicriteria decision making methods in the World. This methodology has been extended by using fuzzy approaches. Researchers have developed new variants of AHP such as ordinary fuzzy AHP (Buckley, 1985), type-2 fuzzy AHP (Kahraman et al., 2014), intuitionistic fuzzy AHP (Xu and Liao, 2014) among others.

Intuitionistic fuzzy AHP or ANP

Hesitant fuzzy AHP or ANP

Type-2 fuzzy AHP or ANP

Pythagorean fuzzy AHP or ANP

Neutrosophic AHP or ANP
