    • An algorithm to compute the transitive closure, a transitive approximation and a transitive opening of a fuzzy proximity 

      Garmendia Salvador, Luis; González del Campo, Ramón; López, Victoria; Recasens Ferrés, Jorge (2009-11)
      Article
      Open Access
      A method to compute the transitive closure, a transitive opening and a transitive approximation of a reflexive and symmetric fuzzy relation is given. Other previous methods in literature compute just the transitive closure, ...
    • Estructura de las similitudes 

      González del Campo, Ramón; Garmendia Salvador, Luis; Recasens Ferrés, Jorge (Center for Soft Computing, 2008)
      Conference report
      Open Access
      En este artículo se define formalmente el concepto de estructura de similaridad, se cuenta el número de estructuras de similaridades hasta dimensión 5, se propone una nomenclatura y un algoritmo que asigna una estructura ...
    • Hesitant fuzzy relations and their transitive closure 

      Garmendia Salvador, Luis; González del Campo, Ramón; Recasens Ferrés, Jorge (2016)
      Conference report
      Open Access
      Hesitant fuzzy relations and some of their operations are defined. A first definition of T-transitive property and its closure is defined.

    • Órdenes parciales para hesitant fuzzy sets 

      Garmendia Salvador, Luis; González del Campo, Ramón; Recasens Ferrés, Jorge (2016)
      Conference report
      Open Access
      Se define un nuevo orden parcial H en el conjunto H de subconjuntos finitos del intervalo unidad. Con este preorden H no es un retículo, pero sí lo son algunos subconjuntos de H interesantes. H se puede inyectar de forma ...
    • Partial orderings for hesitant fuzzy sets 

      Garmendia Salvador, Luis; González del Campo, Ramón; Recasens Ferrés, Jorge (2017-05-01)
      Article
      Open Access
      New partial orderings =o=o, =p=p and =H=H are defined, studied and compared on the set HH of finite subsets of the unit interval with special emphasis on the last one. Since comparing two sets of the same cardinality is a ...
    • Transitive closure of interval-valued fuzzy relations 

      González del Campo, Ramón; Garmendia Salvador, Luis; Recasens Ferrés, Jorge (2013-07)
      Article
      Open Access
      In this paper are introduced some concepts of interval-valued fuzzy relations and some of their properties: reflexivity, symmetry, T-transitivity, composition and local reflexivity. The existence and uniqueness of T-transitive ...
