      Lipschitzian aggregation operators with respect to the natural T - indistin- guishability operator Et and their powers, and with respect to the residuation ! T with respect to a t-norm T and its powers are studied. A ...

    • Approximation of proximities by aggregating T-indistinguishability operators 

      Garmendia, L.; Recasens, J. (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2007)
      Article
      Accés obert
      For a continuous Archimedean t-norm T a method to approximate a proximity relation R (i.e. a reflexive and symmetric fuzzy relation) by a T-transitive one is provided. It consists of aggregating the transitive closure R ...

    • Weighted sums of aggregation operators 

      Calvo Sánchez, Tomasa; Baets, Bernard de; Mesiar, Radko (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
      Article
      Accés obert
      he aim of this work is to investigate when a weighted sum, or in other words, a linear combination, of two or more aggregation operators leads to a new aggregation operator. For weights belonging to the real unit interval, ...
