    • Mathematical aspects of the theory of measures of fuzziness 

      Vivona, Doretta (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
      Article
      Accés obert
      After recalling the axiomatic concept of fuzziness measure, we define some fuzziness measures through Sugeno’s and Choquet’s integral. In particular, for the so-called “homogeneous” fuzziness measures we prove two ...

    • Método numérico para la evaluación holística del riesgo sísmico utilizando la teoría de conjuntos difusos 

      Carreño Tibaduiza, Martha Liliana; Barbat Barbat, Horia Alejandro; Cardona, O.D. (Universitat Politècnica de Catalunya. CIMNE, 2014)
      Article
      Accés obert
      La teoría de conjuntos difusos ofrece un puente entre el procesamiento simbólico y el numérico que permite el uso de conceptos cualitativos útiles en el proceso de toma de decisiones relacionadas con la gestión del riesgo ...

    • Mining and visualizing uncertain data objects and named data networking traffics by fuzzy self-organizing map 

      Karami, Amin; Guerrero Zapata, Manel (CEUR-WS.org, 2014)
      Text en actes de congrés
      Accés obert
      Uncertainty is widely spread in real-world data. Uncertain data-in computer science-is typically found in the area of sensor networks where the sensors sense the environment with certain error. Mining and visualizing ...

    • On the relationship between T-transitivity and approximate equality 

      Boixader Ibáñez, Dionís (2003-01)
      Article
      Accés restringit per política de l'editorial
      The 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 ...

    • Ovchinnikov's automorphisms revisited 

      Trillas i Gay, Enric; Rodríguez, A.; Cubillo Villanueva, Susana (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1994)
      Article
      Accés obert
      In [6] an approach to the representation of synonyms and antonyms via the automorphisms of the De Morgan Algebra [0,1] x was suggested. In [3], Ovchinnikov established a representation theorem for automorphisms of the ...

    • Profit allocation in fuzzy cooperative games in manufacturing and logistics industry 

      Wang, Xiaoyan; Jiang, Liqi; Shu, Lei (OmniaScience, 2014-05)
      Article
      Accés obert
      Purpose: Alliance between manufacturing and logistics industry is a new model of the joint development of the two industries. A reasonable profit allocation mechanism is the key to ensure the stable operation of the alliance, ...

    • Similarity in fuzzy reasoning 

      Klawonn, Frank; Castro Peña, Juan Luis (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1995)
      Article
      Accés obert
      Fuzzy set theory is based on a `fuzzification' of the predicate in (element of), the concept of membership degrees is considered as fundamental. In this paper we elucidate the connection between indistinguishability modelled ...

    • Social aggravation estimation to seismic hazard using classical fuzzy methods 

      González Cárdenas, Rubén; Nebot Castells, M. Àngela; Múgica Álvarez, Francisco; Carreño Tibaduiza, Martha Liliana; Barbat Barbat, Horia Alejandro (Springer, 2015)
      Capítol de llibre
      Accés obert
      In the last years, from a disasters perspective, risk has been dimensioned to allow a better management. However, this conceptualization turns out to be limited or constrained, by the generalized use of a fragmented risk ...

    • Testing satistical hipotheses in fuzzy environment 

      Gregorzewski, Przemyslaw; Hryniewicz, Olgierd (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1997)
      Article
      Accés obert
      In traditional statistics all parameters of the mathematical model and possible observations should be well defined. Sometimes such assumption appears too rigid for the real-life problems, especially while dealing ...

    • The logistic decision making in management accounting with genetic algoritms and fuzzy sets 

      López González, Enrique; Rodríguez-Fernández, M. Ángel; Mendaña Cuervo, Cristina (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2000)
      Article
      Accés obert
      The logistics problems in business environments deal with assignation from a number of sources to a number of destinations. Each source offers amounts of goods, while each destination demands quantities of these goods. The ...

    • Transitive closure and betweenness relations 

      Boixader Ibáñez, Dionís; Jacas Moral, Juan; Recasens Ferrés, Jorge (2001-06)
      Article
      Accés restringit per política de l'editorial
      Indistinguishability operators fuzzify the concept of equivalence relation and have been proved a useful tool in theoretical studies as well as in di0erent applications such as fuzzy control or approximate reasoning. One ...

    • Vagueness and its representations: a unifying look 

      Wygralak, Maciej (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1998)
      Article
