In this paper, on the basis of analyzing some existing limitations in the operational laws
defined for triangular intuitionistic fuzzy numbers (TIFNs), we first proposed some improved …

Fuzzy numbers and intuitionistic fuzzy numbers are introduced in the literature to model
problems involving incomplete and imprecise numerical quantities. Researchers from all …

The aim of this paper is to develop a method for ranking symmetric hexagonal intuitionistic
fuzzy numbers in the process of decision making in a intuitionistic fuzzy environment …

In fuzzy decision-making, incomplete information always leads to uncertain and partially
reliable judgements. The emergence of fuzzy set theory helps decision-makers in handling …

The ranking of intuitionistic fuzzy numbers is paramount in the decision making process in a
fuzzy and uncertain environment. In this paper, a new ranking function is defined, which is …

As the extension of intuitionistic fuzzy numbers (IFNs), linguistic intuitionistic fuzzy numbers
(LIFNs) are proposed. LIFNs are expressed by linguistic variables and take the membership …

With respect to multiple attribute decision making problems with intuitionistic fuzzy
information, some operational laws of intuitionistic fuzzy numbers, score function and …

In this paper, after analyzing on shortcomings of the existing score functions of intuitionistic
fuzzy set (IFS), a new score function based on relative entropy is presented. The risk …

The objective of this paper is to introduce a novel method to compare trapezoidal
intuitionistic fuzzy numbers (TrIFNs). Till now little research has been done regarding the …

As a special intuitionistic fuzzy set on a real number set, trapezoidal intuitionistic fuzzy
numbers (TrIFNs) have the better capability to model ill-known quantities. The purpose of …
