    • Fuzzy numbers, definitions and properties 

      Delgado Calvo-Flores, Miguel; Verdegay, José Luis; Vila Miranda, María Amparo (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1994)
      Article
      Accés obert
      Two different definitions of a Fuzzy number may be found in the literature. Both fulfill Goguen's Fuzzification Principle but are different in nature because of their different starting points. The first one was introduced ...

    • Fuzzy termination criteria in Knapsack problem algorithms 

      Verdegay, José Luis; Vergara-Moreno, Edmundo (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2000)
      Article
      Accés obert
      Fuzzy rule based termination criteria are introduced in two conventional and exact algorithms solving Knapsack Problems. As a consequence two new solution algorithms are obtained. These algorithms are heuristic ones with ...

    • On location problems on fuzzy graphs 

      Moreno Pérez, José Andrés; Moreno Vega, José Marcos; Verdegay, José Luis (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
      Article
      Accés obert
      Location problems concern to a wide set of fields where usually it is assumed that exact data are known. However, in real applications, the location of the facility considered can be full of linguistic vagueness, that ...

    • p-Median problems in a fuzzy environment 

      Kutangila-Mayoya, David; Verdegay, José Luis (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)
      Article
      Accés obert
      In this paper a formulation for the fuzzy p-median model in a fuzzy environment is presented. The model allows to find optimal locations of p facilities and their related cost when data related to the node demands and ...

    • Some practical problems in fuzzy sets-based decision support systems 

      Sancho Royo, Antonio; Verdegay, José Luis; Vergara-Moreno, Edmundo (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
      Article
      Accés obert
      In this paper some problems arising in the interface between two different areas, Decision Support Systems and Fuzzy Sets and Systems, are considered. The Model-Base Management System of a Decision Support System which ...

    • The use of fuzzy connectives to design real-coded genetic algorithms 

      Herrera Triguero, Francisco; Lozano, M.; Verdegay, José Luis (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1994)
      Article
      Accés obert
      Genetic algorithms are adaptive methods that use principles inspired by natural population genetics to evolve solutions to search and optimization problems. Genetic algorithms process a population of search space solutions ...
