Application of Neutrosophic Set Theory in Generalized Assignment Problem [PDF]

open access: yesNeutrosophic Sets and Systems, 2015
This paper presents the application of Neutrosophic Set Theory (NST) in solving Generalized Assignment Problem (GAP). GAP has been solved earlier under fuzzy environment. NST is a generalization of the concept of classical set, fuzzy set, interval-valued

L-Fuzzy Sets and Isomorphic Lattices: Are All the “New” Results Really New? †

open access: yesMathematics, 2018
We review several generalizations of the concept of fuzzy sets with two- or three-dimensional lattices of truth values and study their relationship. It turns out that, in the two-dimensional case, several of the lattices of truth values considered here ...

New operations for interval-valued Pythagorean fuzzy set

open access: yes, 2018
Interval-valued Pythagorean fuzzy set (IVPFS), originally proposed by Peng and Yang, is a novel tool to deal with vagueness and incertitude. As a generalized set, IVPFS has close relationship with interval-valued intuitionistic fuzzy set (IVIFS).

Approximate Reasoning with Fuzzy Booleans [PDF]

open access: yes, 2004
This paper introduces, in analogy to the concept of fuzzy numbers, the concept of fuzzy booleans, and examines approximate reasoning with the compositional rule of inference using fuzzy booleans.

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

open access: yes, 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.

Probability on fuzzy sets and ϵ-fuzzy sets

open access: yesJournal of Mathematical Analysis and Applications, 1983
AbstractThis research investigates the development of probability calculi for fuzzy sets (abbreviated FS's). Two FS algebras are employed, each as a basis for a FS probability calculus. One employs minima for FS intersections and consequently maxima for unions.

Fuzzy Galois connections on fuzzy sets

open access: yes, 1981
In fairly elementary terms this paper presents how the theory of preordered fuzzy sets, more precisely quantale-valued preorders on quantale-valued fuzzy sets, is established under the guidance of enriched category theory.

Intuitionistic fuzzy sets

open access: yesFuzzy Sets and Systems, 1986
By an intuitionistic fuzzy set (IFS) the author understands a pair of generalized characteristic functions and hence a generalization of a fuzzy set. These two functions for each point of the universe of discourse describe separately its degrees of membership and of nonmembership with respect to the IFS they characterize.
