Negation of Pythagorean Fuzzy Number Based on a New Uncertainty Measure Applied in a Service Supplier Selection System

open access: yesEntropy, 2020
The Pythagorean fuzzy number (PFN) consists of membership and non-membership as an extension of the intuitionistic fuzzy number. PFN has a larger ambiguity, and it has a stronger ability to express uncertainty. In the multi-criteria decision-making (MCDM)

Residuated fuzzy logics with an involutive negation

open access: yesArchive for Mathematical Logic, 2000
Residuated fuzzy logic calculi are related to continuous t-norms, which are used as truth functions for conjunction, and their residua as truth functions for implication. In these logics, a negation is also definable from the implication and the truth constant 0̄, namely ¬φ is φ → 0̄.

Bipolar Dissimilarity and Similarity Correlations of Numbers

open access: yesMathematics, 2022
Many papers on fuzzy risk analysis calculate the similarity between fuzzy numbers. Usually, they use symmetric and reflexive similarity measures between parameters of fuzzy sets or “centers of gravity” of generalized fuzzy numbers represented by real ...

H-Max Distance Measure of Bipolar Neutrosophic Sets and an Application to Medical Diagnosis [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
A single-valued neutrosophic set is one of the advanced fuzzy sets that is capable of handling complex real-world information satisfactorily. A development of single-valued neutrosophic set and fuzzy bipolar set, called a bipolar neutrosophic set, was ...

Generator of Fuzzy Implications

open access: yesAlgorithms, 2023
In this research paper, a generator of fuzzy methods based on theorems and axioms of fuzzy logic is derived, analyzed and applied. The family presented generates fuzzy implications according to the value of a selected parameter.

A Study of Generalized QL-Implications

open access: yesMathematics, 2022
In this paper, we introduce and study the GQL′-operations. We prove that this class is a hyper class of the known class of QL′-operations. Similar to QL′-operations, GQL′-operations are not always fuzzy implications.

On Fuzzy Negations and Laws of Contraposition. Lattice of Fuzzy Negations

open access: yesFormalized Mathematics, 2023
Summary This the next article in the series formalizing the book of Baczyński and Jayaram “Fuzzy Implications”. We define the laws of contraposition connected with various fuzzy negations, and in order to make the cluster registration mechanism fully working, we construct some more non-classical examples of fuzzy implications.

The Law of Excluded Middle and the Negation of it in many-valued and Fuzzy Logics [PDF]

open access: yesحکمت و فلسفه, 2008
The philosophical critiques, in twentieth century, on binary paradigm caused the negation of the law of excluded middle as the same as it caused the establishment of many-valued logics and fuzzy logic, while the laws of excluded middle, identity and ...
