    • SR-1: A simulation-based algorithm for the capacitated vehicle routing problem 

      Faulín Fajardo, Francisco Javier; Gilibert Sunyé, Miquel; Juan Pérez, Angel Alejandro; Vilajosana Guillen, Xavier; Ruiz García, Rubén (ISI Proceedings, 2008-12)
      Capítol de llibre
      Accés obert
      In this paper we present SR-1, a simulation-based heuristic algorithm for the capacitated vehicle routing oroblem (CVRP). Given a CVRP instance, SR-1 uses an initial “good solution”, such as the one provided by the classical ...

    • Structural reliability and availability analysis through simulation 

      Juan Pérez, Angel Alejandro; Simosa, Jorge; Faulín, Javier; Monteforte, Arai; Guo, Harry (2011)
      Article
      Accés obert
      In this paper, some potential applications of simulation in structural reliability and availability are presented. Unlike the analytical methods, where assumptions that simplify complex analysis often need to be made, ...

    • Teaching mathematics online in the european area of higher education: an instructors’ point of view 

      Juan Pérez, Angel Alejandro; Steegmann Pascual, Cristina; Huertas Sánchez, María Antonia; Martínez-Argüelles, María-Jesús; Simosa, J (Taylor & Francis Ltd., 2011)
      Article
      Accés restringit per política de l'editorial
      This article first discusses how information technologies are changing the way knowledge is delivered at universities worldwide. Then, the article reviews some of the most popular learning management systems available today ...

    • Using discrete-event simulation to design reliable and cost-efficient civil engineering structures 

      Juan Pérez, Angel Alejandro; Ferrer Biosca, Alberto; Serrat Piè, Carles; Faulín, Javier; Hester, J.; López Brosa, Pere (2009-09)
      Text en actes de congrés
      Accés obert
      In this paper the topic of Structural Reliability Analysis and its importance in modern Civil Engineering is introduced. Throughout the paper, some advantages that simulation-based approaches offer with respect to other ...

    • Using parallel & distributed computing for solving real-time vehicle routing problems with stochastic demands 

      Juan Pérez, Angel Alejandro; Faulín, Javier; Jorba, Josep; Caceres, J; Marquès Puig, Joan Manel (2011)
      Article
      Accés restringit per política de l'editorial
      This paper focuses on the Vehicle Routing Problem with Stochastic Demands (VRPSD) and discusses how Parallel and Distributed Computing Systems can be employed to efficiently solve the VRPSD. Our approach deals with uncertainty ...

    • Using simulation to provide alternative solutions to the flowshop sequencing problem 

      Juan Pérez, Angel Alejandro; Guix, Antoni; Adelantado Freixer, Ferran; Fonseca Casas, Pau; Ruiz García, Rubén (2010)
      Text en actes de congrés
      Accés obert
      In this paper we present SS-GNEH, a simulation-based algorithm for the Permutation Flowshop Sequencing Problem (PFSP). Given a PFSP instance, the SSGNEH algorithm incorporates a randomness criterion to the classical NEH ...

    • Using specification and description language to represent users’ profiles in OMNET++ simulations 

      Fonseca Casas, Pau; Roma Niñerola, Miquel; Juan Pérez, Angel Alejandro (2011)
      Text en actes de congrés
      Accés obert
      Omnet++ is a powerful and open-source simulation tool which is basically intended to model discrete-event systems. In particular, Omnet++ is extensively used to model and simulate computer networks. Typically, when a Wide ...
