Interval-valued contractive fuzzy negations [PDF]

open access: yesInternational Conference on Fuzzy Systems, 2010
In this work we consider the concept of contractive interval-valued fuzzy negation, as a negation such that it does not increase the length or amplitude of an interval. We relate this to the concept of Lipschitz function. In particular, we prove that the only strict (strong) contractive interval-valued fuzzy negation is the one generated from the ...

New Transitivity of Atanassov’s Intuitionistic Fuzzy Sets in a Decision Making Model

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2021
Atanassov’s intuitionistic fuzzy sets and especially his intuitionistic fuzzy relations are tools that make it possible to model effectively imperfect information that we meet in many real-life situations.

Parametric Fuzzy Implications Produced via Fuzzy Negations with a Case Study in Environmental Variables

open access: yes, 2021
In this paper, we present a new Fuzzy Implication Generator via Fuzzy Negations which was generated via conical sections, in combination with the well-known Fuzzy Conjunction.

Ordinal Sums of Fuzzy Negations: Main Classes and Natural Negations

open access: yesCoRR, 2019
In the context of fuzzy logic, ordinal sums provide a method for constructing new functions from existing functions, which can be triangular norms, triangular conorms, fuzzy negations, copulas, overlaps, uninorms, fuzzy implications, among others. As our main contribution, we establish conditions for the ordinal sum of a family of fuzzy negations to be

A random set and prototype theory interpretation of intuitionistic fuzzy sets [PDF]

open access: yes, 2010
An interpretation of intuitionistic fuzzy sets is proposed based on random set theory and prototype theory. The extension of fuzzy labels are modelled by lower and upper random set neighbourhoods, identifying those element of the universe within an ...

Ordinal Sums of De Morgan Triples

open access: yesTrends in Computational and Applied Mathematics, 2018
In this paper we consider the ordinal sum of the summands (a_i, b_i, T_i) ((a_i, b_i, S_i)), where (T_i)_{i\in I}$ $((S_i)_{i\in I}) are a family of t-(co)norms and $(]a_i, b_i[)_{i\in I}$ a family of nonempty, pairwise disjoint open subintervals of [0,1]

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.
