    • A geometrical approach to aggregation 

      Recasens Ferrés, Jorge (2007-12)
      Article
      Accés restringit per política de l'editorial
      Considering the family F of contour curves F = fh(x; y) = k) of an (idempotent) aggregation operator h in two variables as a one-parametric family of curves, the differential equation y0 = f(x; y) having F as general ...

    • Aggregation operators and quadric hypersurfaces 

      Recasens Ferrés, Jorge (Springer, 2013)
      Article
      Accés obert
      Aggregation operators that are quadric hypersurfaces are studied. The interest lays in the fact that the most popular aggregation operators are indeed quadric hypersurfaces.

    • Aggregation, non-contradiction ans excluded-middle 

      Pradera Gómez, Ana; Trillas i Gay, Enric (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2006)
      Article
      Accés obert
      This paper investigates the satisfaction of the Non-Contradiction (NC) and Excluded-Middle (EM) laws within the domain of aggregation operators. It provides characterizations both for those aggregation operators that satisfy ...

    • An aggregation rule under uncertainty 

      Freixas Bosch, Josep (2023)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Many decision-making situations require the evaluation of several agents or judges. In a situation where agents evaluate candidates, the question arises of how best to aggregate evaluations so as to compare the candidates. ...

    • On aggregation operators of transitive similarity and dissimilarity relations 

      Orozco Luquero, Jorge; Belanche Muñoz, Luis Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2004)
      Text en actes de congrés
      Accés obert
      Similarity and dissimilarity are widely used concepts. One of the most studied matters is their combination or aggregation. However, transitivity property is often ignored when aggregating despite being a highly important ...

    • On the learning of weights in some aggregation operators: the weighted mean and OWA operators 

      Torra Ferré, Vicenç (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
      Article
      Accés obert
      We study the determination of weights for two types of aggregation operators: the weighted mean and the OWA operator. We assume that there is at our disposal a set of examples for which the outcome of the aggregation ...
