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 …

The aim of this work is to present some aggregation operators with triangular intuitionistic
fuzzy numbers and study their desirable properties. Firstly, the score function and the …

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

Triangular intuitionistic fuzzy number (TIFN) is a more generalized platform for expressing
imprecise, incomplete, and inconsistent information when solving multi-criteria decision …

The aim of this paper is to develop some new generalized aggregation operators for
triangular intuitionistic fuzzy numbers (TIFNs) and apply to multi-attribute group decision …

Complex intuitionistic fuzzy set (CIFS) is a special intuitionistic fuzzy set where the
membership and non-membership degrees are expressed by a complex-valued …

Intuitionistic trapezoidal fuzzy numbers and their operational laws are defined. Based on
these operational laws, some aggregation operators, including intuitionistic trapezoidal …

Complex intuitionistic fuzzy set (CIFS) is a distinctive intuitionistic fuzzy set (IFS) in which the
membership degrees are determined on the unit disc of the complex plane and can more …

The purpose of this paper is to introduce the concepts of Dombi t-norm and Dombi t-conorm
to aggregate intuitionistic fuzzy information. First, we have proposed some new operational …

In this paper, we first defined intuitionistic normal fuzzy numbers as well as their operational
laws and score function. Next, we proposed some aggregation operators including ordered …
