    Article
    Open Access
    The business achievement via e-commerce is getting more important at the present time. E-commerce implies several activities. One of the most significant activity is the consummation of negotiations between sellers and ...
  • A map characterizing the fuzzy points and columns of a T-indistinguishability operator 

    Boixader Ibáñez, Dionís; Recasens Ferrés, Jorge (2005-10)
    Article
    Open Access
    A new map (ΛE) between fuzzy subsets of a universe X endowed with a T-indistinguishability operator E is introduced. The main feature of ΛE is that it has the columns of E as fixed points, and thus it provides us with a ...
  • A model for CAGD using fuzzy logic 

    Jacas Moral, Juan; Monreal Pujadas, Amadeo; Recasens Ferrés, Jorge (1997-01)
    Article
    Restricted access - publisher's policy
    This paper presents a first approach to a system based on fuzzy logic for the design of curves and surfaces in the context of computer aided geometric design. Bézier curves and surfaces can be seen as particular cases of ...
  • A new assessment method of new energy in regional sustainable development based on hesitant fuzzy information 

    Yao, Hongdi; Li, Wenxing (OmniaScience, 2014-12)
    Article
    Open Access
    Purpose: The new energy has been an important driving force in region sustainable development. It is a critical issue to evaluate the role of new energy in region sustainable development. Design/methodology/approach: ...
  • A qualitative reasoning approach for measuring citizens’ satisfaction

  • A reformulation of entropy in the presence of indistinguishability operators 

    Recasens Ferrés, Jorge; Hernández, E (2002-06)
    Article
    Restricted access - publisher's policy
    This paper deals with the measurement of entropy when an indistinguishability relation on the set of events has been defined. Our approach states that entropy could be measured in terms of the observed distinguishability ...
  • A train dispatching model based on fuzzy passenger demand forecasting during holidays 

    Dou, Fei; Xu, Jie; Wang, Li; Jia, Limin (School of Industrial and Aeronautic Engineering of Terrassa (ETSEIAT). Universitat Politècnica de Catalunya (UPC), 2013-04)
    Article
