Interval Valued intuitionistic Fuzzy Homomorphism of BF-algebras [PDF]

, 2013
The notion of interval-valued intuitionistic fuzzy sets was first introduced by Atanassov and Gargov as a generalization of both interval-valued fuzzy sets and intuitionistic fuzzy sets. Satyanarayana et.

A Novel Method of the Generalized Interval-Valued Fuzzy Rough Approximation Operators

The Scientific World Journal, 2014
Rough set theory is a suitable tool for dealing with the imprecision, uncertainty, incompleteness, and vagueness of knowledge. In this paper, new lower and upper approximation operators for generalized fuzzy rough sets are constructed, and their ...

Interval-Valued Pythagorean Hesitant Fuzzy Set and Its Application to Multiattribute Group Decision-Making

Complexity, 2020
Pythagorean hesitant fuzzy sets are widely watched because of their excellent ability to deal with uncertainty, imprecise and vague information. This paper extends Pythagorean hesitant fuzzy environments to interval-valued Pythagorean hesitant fuzzy ...

Comparison of Interval-valued fuzzy sets, Intuitionistic fuzzy sets, and bipolar-valued fuzzy sets [PDF]

Journal of Korean Institute of Intelligent Systems, 2004
There are several kinds of fuzzy set extensions in the fuzzy set theory. Among them, this paper is concerned with interval-valued fuzzy sets, intuitionistic fuzzy sets, and bipolar-valued fuzzy sets. In interval-valued fuzzy sets, membership degrees are represented by an interval value that reflects the uncertainty in assigning membership degrees.

A Geometric Interpretation of the Neutrosophic Set - A Generalization of the Intuitionistic Fuzzy Set

, 2011
In this paper we generalize the intuitionistic fuzzy set (IFS), paraconsistent set, and intuitionistic set to the neutrosophic set (NS). Several examples are presented.

Neutrality and Many-Valued Logics [PDF]

, 2007
In this book, we consider various many-valued logics: standard, linear, hyperbolic, parabolic, non-Archimedean, p-adic, interval, neutrosophic, etc. We survey also results which show the tree different proof-theoretic frameworks for many-valued logics, e.

(α,β)-Interval-valued intuitionistic fuzzy subgroups [PDF]

Notes on IFS
In this paper, (α,β)-interval-valued intuitionistic fuzzy subgroups are studied. The definition of these structures are given by using (α,β)-interval-valued intuitionistic fuzzy sets. The structural properties of these subgroups are studied.

Decision-making algorithm based on the energy of interval-valued fuzzy soft sets

Mathematics in Applied Sciences and Engineering
In our work, we continue to explore the properties of interval-valued fuzzy soft sets, which are obtained by combining interval-valued fuzzy sets and soft sets.

Soft Interval-Valued Neutrosophic Rough Sets [PDF]

Neutrosophic Sets and Systems, 2015
In this paper, we first defined soft interval-valued neutrosophic rough sets(SIVN- rough sets for short) which combines interval valued neutrosophic soft set and rough sets and studied some of its basic properties.
