A new multiple attribute decision making method based on linear programming methodology and novel score function and novel accuracy function of interval-valued intuitionistic fuzzy values [PDF]

open access: yes, 2018
Score functions and accuracy functions of interval-valued intuitionistic fuzzy values (IV- IFVs) play important roles in dealing with multiple attribute decision making (MADM) problems in interval-valued intuitionistic fuzzy (IVIF) environments.

Operators on circular interval-valued intuitionistic fuzzy sets [PDF]

open access: yesNotes on IFS
A circular interval-valued intuitionistic fuzzy set extends the concept of a circular intuitionistic fuzzy set by incorporating membership and non-membership degrees, which are represented as closed intervals with a given radius r, both confined within ...

On the relationship between intuitionistic fuzzy sets and some other extensions of fuzzy set theory

open access: yes, 2002
In a previous paper we presented the relationship between intuitionistic fuzzy sets (Atanassov) and some other extensions of fuzzy set theory, such as L-fuzzy sets (Goguen), interval valued fuzzy sets (Sambuc), interval valued intuitionistic fuzzy sets ...

Interval-Valued Intuitionistic Fuzzy Multicriteria Group Decision Making Based on VIKOR and Choquet Integral

open access: yesJournal of Applied Mathematics, 2013
An effective decision making approach based on VIKOR and Choquet integral is developed to solve multicriteria group decision making problem with conflicting criteria and interdependent subjective preference of decision makers in a fuzzy environment where

Semiring-Valued Fuzzy Sets and F-Transform

open access: yes, 2021
The notion of a semiring-valued fuzzy set is introduced for special commutative partially pre-ordered semirings, including basic operations with these fuzzy structures. It is showed that many standard MV-algebra-valued fuzzy type structures with standard

A Comparative Analysis on Geometric Measure in Intuitionistic Fuzzy Set and Interval-Valued Intuitionistic Fuzzy Set

open access: yesInternational Journal of Scientific Research in Science, Engineering and Technology, 2019
Intuitionistic Fuzzy set (IFS) was proposed in early 80’s. It is a well known theory. As a developer in Fuzzy Mathematics, interval – valued Intuitionistic Fuzzy sets (IVIFS) were developed afterwards by Gargo and Atanssov. It has a wide range of applications in the field of Optimization and algebra.

An Adjustable Reduction Approach of Interval-valued Intuitionistic Fuzzy Soft Sets for Decision Making [PDF]

open access: yes, 2017
Parameter reduction methods have been adopted by many scientific communities since it provides the basic concept for removing irrelevant features and subset of parameters that provides the same descriptive or decisionability as the entire set of ...

Generation of Interval-Valued Fuzzy Negations from Trillas’ Theorem. The Case of Interval Type-2 Fuzzy Sets

open access: yes, 2015
In this work we introduce a method for building interval-valued negations using the characterization theorem for strong negations which was proposed by Trillas in 1979.
