A map characterizing the fuzzy points and columns of a T-indistinguishability operator
(2005-10)
Article
Accés obertA new map (ΛE) between fuzzy subsets of a universe X endowed with a T-indistinguishability operator E is introduced. The main feature of ΛE is that it has the columns of E as fixed points, and thus it provides us with a ... -
Consequence operators, interior operators and fuzzy relations
(2022-12-01)
Article
Accés restringit per política de l'editorialIn this article the relationship between fuzzy consequence and fuzzy interior operators with fuzzy relations is analyzed. While the situation has been studied in depth if the fuzzy relation is a *-preorder it is not the ... -
Eigenvectors and generators of fuzzy relations
(-, 1992)
Text en actes de congrés
Accés restringit per política de l'editorialA new geometric approach to the study of the eigenvectors is provided. The T-eigenvectors of a T-indistinguishability operator are characterized as its generators in the sense of the representation theorem of L. Valverde ... -
Fuzzy set theory for cumulative trauma prediction
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
Article
Accés obertA widely used fuzzy reasoning algorithm was modified and implemented via an expert system to assess the potential risk of employee repetitive strain injury in the workplace. This fuzzy relational model, known as the ... -
Intuitionistic fuzzy relations (Part II) Effect of Atanassov's operators on the properties of the intuitionistic fuzzy relations
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1995)
Article
Accés obertIn this paper we study the effect of Atanassov's operator on the properties of properties reflexive, symmetric, antisymmetric, perfect antisymmetric and transitive intuitionistic fuzzy relations. We finish the paper analysing ... -
On the degree of transitivity of a fuzzy relation
(2021-01-01)
Article
Accés obertConsidering a family generated from a t-norm T, the degree of T-transitivity of a fuzzy relation R is revisited and proved to coincide with the greatest c for which R is -transitive. This fact gives rise to the study of ... -
On the relationship between T-transitivity and approximate equality
(2003-01)
Article
Accés restringit per política de l'editorialThe paper discusses the suitability of T-transitivity for modelling approximate equality. It explains how T-transitivity, a property suitable for modelling vagueness, can still be used to handle the imprecision inherent ... -
Transitivity of fuzzy relations under discretization
(2013-07-10)
Article
Accés restringit per política de l'editorialFuzzy transitivity is a key property for many fuzzy relational structures, such as fuzzy preorders and equivalences. Theoretical models for practical problems which are based on fuzzy relations make use of continuous scales, ...
