In this paper, we propose the concept of a linguistic interval-valued Atanassov intuitionistic
fuzzy set (LIVAIFS), whose membership and nonmembership degrees are represented by …

In this paper, we investigate the group decision making problems in which all the information
provided by the decision-makers is presented as interval-valued intuitionistic fuzzy decision …

An interval-valued intuitionistic fuzzy set (IVIFS) is the extension of an intuitionistic fuzzy set
(IFS). The ranking of IVIFSs is very important for the interval-valued intuitionistic fuzzy …

This article aims to develop a novel hybrid multi‐attribute group decision‐making approach
under interval‐valued intuitionistic fuzzy sets (IVIFS) by integrating variable weight …

Linguistic intuitionistic fuzzy numbers (LIFNs) is a new concept in describing the intuitionistic
fuzzy information, which membership and non-membership are expressed by linguistic …

This paper investigates an order relation of interval-valued intuitionistic fuzzy values (IVIFVs)
based on possibility degree and divergence degree and applies it to multi-attribute group …

This chapter develops a new method for solving multiple attribute group decision-making
(MAGDM) problems with Atanassov's interval-valued intuitionistic fuzzy values (AIVIFVs) and …

Interval-valued intuitionistic fuzzy set (IVIFS) is a flexible method to deal with uncertainty and
fuzziness. For the past few years, extensive researches about the multi-attribute group …

An extension of TOPSIS, a multi-criteria interval-valued intuitionistic fuzzy decision making
technique, to a group decision environment is investigated, where inter-dependent or …

This study investigates the group decision making under interval-valued intuitionistic fuzzy
environment in which the attributes and experts are in different priority level. We first propose …
