    • A characterization for residuated implications on J [0, 1]. Application to the L-fuzzy concept theory. 

      Alcalde, Maria Cristina; Burusco Juandeaburre, Ana; Fuentes-González, Ramón (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)
      Article
      Accés obert
      In this paper, a new characterization for the interval-valued residuated fuzzy implication operators is presented, with which it is possible to use them in a simple and efficient way, since the calculation of the values ...

    • A first approach to the multipurpose relational database server 

      Blanco, Ignacio J.; Martínez-Cruz, Carmen; Serrano Chica, José María; Vila Miranda, María Amparo (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)
      Article
      Accés obert
      In this paper, an architecture and an implementation of a multipurpose relational database server are proposed. This architecture enables classical queries to be executed, deductions to be made, and data mining operations to ...

    • A multi-granular linguistic model to evaluate the suitability of installing an ERP system 

      Sánchez, Pedro José; Pérez, Luís G.; Mata, Francisco; López-Herrera, Antonio Gabriel (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)
      Article
      Accés obert
      The use of Enterprise Resource Planning (ERP) has shown clearly useful and economically profitable in most very large organizations which manage a great deal of data in their information systems. Nevertheless, the decision ...

    • A neural implementation of multi-adjoint logic programs via sf-homogenization 

      Medina Moreno, Jesús; Mérida-Casermeiro, Enrique; Ojeda Aciego, Manuel (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)
      Article
      Accés obert
      A generalization of the homogenization process needed for the neural im- plementation of multi-adjoint logic programming (a unifying theory to deal with uncertainty, imprecise data or incomplete information) is presented ...

    • Applying fuzzy logic in video surveillance systems 

      Molina, José Manuel; García, Jesús; Pérez, Oscar; Carbó, Javier; Berlanga, Antonio; Portillo García, Javier Ignacio (2005)
      Article
      Accés obert
      In this work, the application of fuzzy logic in surveillance systems based on cameras is Analyzed. Three different fuzzy systems have been tested and compared with a crisp decision system. The first one has been developed ...

    • Characterizing intraregular semigroups by intuitionistic fuzzy sets 

      Hong, Yin; Fang, X. (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)
      Article
      Accés obert
      In this paper, we give some theorems which characterizes the intraregular semigroups in terms of intuitionistic fuzzy left, right, and biideals.

    • Completing an uncertainty criterion of classification 

      Abellán, Joaquín (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)
      Article
      Accés obert
      We present a variation of a method of classification based in uncertainty on credal set. Similarly to its origin it use the imprecise Dirichlet model to create the credal set and the same uncertainty measures. It take ...

    • Editorial [12th. Spanish Conference on Fuzzy Logic and Fuzzy Technologies, Jaen, 2004: selected papers] 

      Martínez López, Luis; Jesús Díaz, Ma José del; Castro Peña, Juan Luis (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)

    • Majority multiplicative ordered weighting geometric operators and their use in the aggregation of multiplicative preference relations 

      Pelayo Melero, Ignacio Manuel; Doña, Jesús Maria; Mesas, Alejandro (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)
      Article
      Accés obert
      In this paper, we introduced the majority multiplicative ordered weighted geometric (MM-OWG) operator and its properties. This is a general type of the aggregate dependent weights which we have applied in geometric ...

    • 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 ...

    • Systems of possibilistic regressions: a case study in ecological inference 

      Donoso, Sergi; Marín Ruíz, Nicolás; Vila Miranda, María Amparo (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)
      Article
      Accés obert
      This work introduces how possibilistic regression can be used in the case of non symmetrical triangular membership functions, building a system of regressions, so that suitable restrictions for each particular problem can ...
