  • Multiobjective memetic algorithms for time and space assembly line balancing 

    Chica, Manuel; Cordon, Oscar; Damas, Sergio; Bautista Valhondo, Joaquín (2012-01-11)
    Article
    Restricted access - publisher's policy
    This paper presents three proposals of multiobjective memetic algorithms to solve a more realistic extension of a classical industrial problem: time and space assembly line balancing. These three proposals are, respectively, ...
  • Solving the Fm|block|Cmax problem using bounded dynamic programming 

    Bautista Valhondo, Joaquín; Cano Pérez, Alberto; Companys Pascual, Ramón; Ribas Vila, Immaculada (2011-11)
    Article
    Open Access
    We present some results attained with two variants of Bounded Dynamic Programming algorithm to solve the Fm|block|Cmax problem using as an experimental data the well-known Taillard instances. We have improved the best known ...
  • A dynamic programming based heuristic for the assembly line balancing problem 

    Bautista Valhondo, Joaquín; Pereira Gude, Jordi (Elsevier, 2009-05-01)
    Article

    The simple assembly line balancing problem is the simplification of a real problem associated to the assignment of the elementary tasks required for assembly of a product in an assembly line. This problem has been extensively ...
  • The Windy clustered prize-collecting arc-routing problem 

    Corberan, Angel; Fernández Aréizaga, Elena; Franquesa Niubó, Carles; Sanchis, Jose Maria (2011-08)
    Article
    Restricted access - confidentiality agreement
    This paper introduces the windy clustered prize-collecting arc-routing problem. It is an arc-routing problem where each demand edge is associated with a profit that is collected once if the edge is serviced, independent of ...
  • ‘Low-cost educational videos’ for engineering students: a new concept based on video streaming and YouTube channels 

    Garriga Garzón, Federico; Rajadell Carreras, Manuel; García-Almiñana, Daniel; Sunyer Torrents, Albert; Fernández Alarcón, Vicenç; Simó Guzmán, Pep; Algaba Joaquín, Inés María; Albareda Sambola, Maria; Salán Ballesteros, Maria Núria; Amante García, Beatriz; Enache, Cristina Mihaela; Bravo Ibarra, Edna Rocío (2011)
    Article
    Restricted access - publisher's policy
    There are many papers that present the problems of educational videos: need of a high number of resources to create them, excess of information in the majority of videos, gaps of information between videos and the rest ...
  • Travel time forecasting and dynamic origin-destination estimation for freeways based on bluetooth traffic monitoring 

    Barceló Bugeda, Jaime; Montero Mercadé, Lídia; Marquès, Laura; Carmona Bautista, Carlos (2010)
    Article
    Open Access
    From the point of view of the information supplied by an ATIS to the motorists entering a freeway of one of the most relevant is the Forecasted Travel Time, that is the expected travel time that they will experience when ...
  • An integrated GPS/PDA/GIS telegeoprocessing system for traffic & environment 

    Ramos, Ana Luísa; Vasconcelos Ferreira, José; Barceló Bugeda, Jaime (Advisory Board, 2009)
    Article
    Open Access
    The development of sustainable urban transport networks is a present priority for world leaders, national governors and local authorities. The challenge is to increase mobility reducing the adverse impacts of transport. ...
  • Including different kinds of preferences in a multi-objective ant algorithm for time and space assembly line balancing on different Nissan scenarios 

    Chica, Manuel; Cordon, Oscar; Damas, Sergio; Bautista Valhondo, Joaquín (2011-01)
    Article
    Restricted access - publisher's policy
    Most of the decision support systems for balancing industrial assembly lines are designed to report a huge number of possible line configurations, according to several criteria. In this contribution, we tackle a more ...
  • Multiobjective constructive heuristics for the 1/3 variant of the time and space assembly line balancing problem: ACO and random greedy search 

    Chica, Manuel; Cordon, Oscar; Damas, Sergio; Bautista Valhondo, Joaquín (2010-09-15)

  • The multi-period incremental service facility location problem 

    Albareda Sambola, Maria; Fernández Aréizaga, Elena; Hinojosa, Yolanda; Puerto Albandoz, Justo (2009)
    Article
    Restricted access - publisher's policy
    In this paper we introduce the multi-period incremental service facility location problem where the goal is to set a number of new facilities over a finite time horizon so as to cover dynamically the demand of a given set ...
  • Lagrangean bounds for the optimum communication spanning tree problem 

    Contreras, I.; Fernández Aréizaga, Elena; Marín, Alfredo (Springer Verlag, 2010)
    Article
    Restricted access - publisher's policy
    This paper considers the Optimum Communication Spanning Tree Problem. An integer programming formulation that yields tight LP bounds is proposed. Given that the computational effort required to obtain the LP bounds ...
  • GEVA: geometric variability-based approaches for identifying patterns in data
