  • Improving the resolution of the simple assembly line balancing problem type E 

    Corominas Subias, Albert; García Villoria, Alberto; Pastor Moreno, Rafael (Institut d'Estadística de Catalunya, 2016-07-01)
    Article
    Accés obert
    The simple assembly line balancing problem type E (abbreviated as SALBP-E) occurs when the number of workstations and the cycle time are variables and the objective is to maximise the line efficiency. In contrast with other ...
  • The multi-objective assembly line worker integration and balancing problem of type-2 

    Moreira, Mayron César O.; Pastor Moreno, Rafael; Costa, Alysson E.; Miralles, Cristobal (2017-06-01)
    Article
    Accés restringit per política de l'editorial
    The consideration of worker heterogeneity in assembly lines has received a fair amount of attention in the literature in the past decade. Most of this exploration uses as motivation the example of assembly lines in sheltered ...

    Ribas Vila, Immaculada; Companys Pascual, Ramon; Tort-Martorell Llabrés, Xavier (2017-05-15)
    Article
    Accés restringit per política de l'editorial
    We consider the NP-hard problem of scheduling n jobs in F identical parallel flow shops, each consisting of a series of m machines, and doing so with a blocking constraint. The applied criterion is to minimize the makespan, ...

  • An algorithm for a bi-objective parallel machine problem with eligibility, release dates and delivery times of the jobs 

    Mateo Doll, Manuel; Teghem, Jacques; Tuyttens, Daniel (2016-01-01)
    Article
    Accés obert
    The scheduling of parallel machines is a well-known problem in many companies. Nevertheless, not always all the jobs can be manufactured in any machine and the eligibility appears. Based on a real-life problem, we present ...
