Normal intuitionistic fuzzy numbers (NIFNs), which use normal fuzzy numbers to express
their membership and non-membership functions, can reflect the evaluation information …

The aim of this study is to introduce a novel generalized distance measure for interval
valued intuitionistic fuzzy sets and to illustrate the applicability of the proposed distance …

The concept of intuitionistic fuzzy sets is the generalization of the concept of fuzzy sets. The
theory of intuitionistic fuzzy sets is well suited to dealing with vagueness. Recently …

Intuitionistic fuzzy variables are powerful tools to denote positive and negative information
simultaneously. Considering the situation where decision makers (DMs) may adopt different …

Due to the complexity of decision making under uncertainty and the existence of various and
often conflicting criteria, several methods have been proposed to facilitate decision making …

With respect to multiple attribute group decision making (MAGDM) problems in which both
the attribute weights and the expert weights take the form of real numbers, attribute values …

Intuitionistic fuzzy set (IFS), a classical extension of fuzzy set, is a powerful tool to describe
fuzzy information in multi-criteria decision-making (MCDM) because of its membership and …

In this paper, we propose a multi-attribute group decision-making (MAGDM) method based
on Dempster–Shafer Evidence Theory (DST) and linguistic intuitionistic fuzzy numbers …

The interval-valued intuitionistic fuzzy weighted arithmetic average operator, the interval-
valued intuitionistic fuzzy weighted geometric average operator, and an accuracy function of …

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 …
