  • An agile simheuristic for the stochastic team task assignment and orienteering problem: applications to unmanned aerial vehicles 

    Panadero, Javier; Juan Pérez, Ángel Alejandro; Grifoll Colls, Manel; Dehghanimohamamdabadi, Mohammad; Freixes, Alfons; Serrat Piè, Carles (2020)
    Conference report
    Open Access
    Efficient coordination of unmanned aerial vehicles (UAVs) requires the solving of challenging operational problems. One of them is the integrated team task assignment and orienteering problem (TAOP). The TAOP can be seen ...

  • Added resistance parametrizations due to waves in a weather ship routing system 

    Borén Altés, Clara; Falevitch, Loïc; Castells Sanabra, Marcel·la; Grifoll Colls, Manel (2019)
    Conference report
    Open Access
    This contribution compares the parametrization of the wave effect on navigation in a weather ship routing system using three different formulations. The investigation is supported by the use of a ship routing system, the ...

  • New strategies for environmental management in harbours: the case of the Tarragona port monobuoy 

    Morell, Mariano; Espino Infantes, Manuel; Grifoll Colls, Manel; Mestres Ridge, Marc (Edicions UPC, 2020)
    Conference report
    Open Access
    Ports are a potential focus of sea pollution and therefore port authorities and operators have a key role on the sustainability and environmental protection of the coastal waters. In the last decades, monitoring techniques ...

  • Dynamics of the rhythmic morphology on the low-energy Trabucador beach (Ebro delta) 

    Mujal Colilles, Anna; Grifoll Colls, Manel; Ribas Prats, Francesca; Falqués Serra, Albert (Consejo Superior de Investigaciones Científicas (CSIC), 2019)
    Conference report
    Open Access
    Observations of rhythmic morphology along the Trabucador beach are contrasted with two numerical models to unravel the mechanisms of their formation. The Trabucador is a long narrow barrier at the SW side of the Ebro ...

  • A simheuristic for the unmanned aerial vehicle surveillance-routing problem with stochastic travel times and reliability considerations 

    Panadero, Javier; Juan Pérez, Ángel Alejandro; Serrat Piè, Carles; Grifoll Colls, Manel; Freixes, Alfons (2019)
    Conference report
    Open Access
    In the unmanned aerial vehicle (UAV) surveillance-routing problem, a limited fleet of UAVs with driving-range limitations have to visit a series of target zones in order to complete a monitoring operation. This operation ...

  • Cruise port activity evolution in the Mediterranean Sea: a compositional data approach 

    Grifoll Colls, Manel; Karlis, Thanassis (2019)
    Conference report
    Restricted access - publisher's policy
    Since 1980, the cruise industry has recorded an impressive average passenger growth rate of approximately 7% per annum. From a methodological point of view, the evolution of the cruise traffic in a port system has been ...

  • Introduction of autonomous vehicles in traffic flow: theoretical and practical challenges 

    Martínez Díaz, Margarita; Soriguera Martí, Francesc (Universidad de Oviedo, 2018)
    Conference report
