    This paper studies Minimum Spanning Trees under incomplete information assuming that it is only known that vertices belong to some neighborhoods that are second order cone representable and distances are measured with a ...
  • Stochastic optimal generation bid to electricity markets with emissions risk constraints 

    Heredia, F.-Javier (Francisco Javier); Cifuentes Rubiano, Julián; Corchero García, Cristina (2018-02-01)
    Article
    Open Access
    There are many factors that influence the day-ahead market bidding strategies of a generation company (GenCo) within the framework of the current energy market. Environmental policy issues are giving rise to emission ...

    This paper introduces the Flexible Periodic Vehicle Routing Problem (FPVRP) where a carrier has to establish a distribution plan to serve his customers over a planning horizon. Each customer has a total demand that must ...
  • Heuristic solucions to the facility location problem with general Bernoulli demands 

    Albareda Sambola, Maria; Fernández Aréizaga, Elena; Saldanha da Gama, Francisco (2017-09-28)
    Article
    Open Access
    In this paper, a heuristic procedure is proposed for the facility location problem with general Bernoulli demands. This is a discrete facility location problem with stochastic demands that can be formulated as a two-stage ...
  • Comparison of production strategies and degree of postponement when incorporating additive manufacturing to product supply chains 

    Minguella Canela, Joaquim; Muguruza Blanco, Asier; Ramón Lumbierres, Daniel Jacobo; Heredia, F.-Javier (Francisco Javier); Gimeno Feu, Robert; Guo, Ping; Hamilton, Mary; Shastry, Kiron; Webb, Sunny (2017-10-06)
    Article
    Open Access
    The best-selling products manufactured nowadays are made in long series along rigid product value chains. Product repetition and continuous/stable manufacturing is seen as a chance for achieving economies of scale. ...
  • On geometrical properties of preconditioners in IPMs for classes of block-angular problems 

    Castro Pérez, Jordi; Nasini, Stefano (2017)
    Article
    Open Access
    One of the most efficient interior-point methods for some classes of block-angular structured problems solves the normal equations by a combination of Cholesky factorizations and preconditioned conjugate gradient for, ...
  • A linear optimization based method for data privacy in statistical tabular data 

    Castro Pérez, Jordi; González Alastrué, José Antonio (2017-06-15)
    Article
    Open Access
    National Statistical Agencies routinely disseminate large amount of data. Prior to dissemination these data have to be protected to avoid releasing confidential information. Controlled tabular adjustment (CTA) is one of ...
  • The probabilistic p-center problem: Planning service for potential customers 

    Martínez Merino, Luisa I.; Albareda Sambola, Maria; Rodríguez Chía, Antonio Manuel (Elsevier, 2017-10-16)
    Article
    Restricted access - publisher's policy
    This work deals with the probabilistic p-center problem, which aims at minimizing the expected maximum distance between any site with demand and its center, considering that each site has demand with a specific probability. ...
  • Taking advantage of unexpected WebCONSORT results 

    Cobo Valeri, Erik; González Alastrué, José Antonio (2016)
    Article
    Open Access
    To estimate treatment effects, trials are initiated by randomising patients to the interventions under study and finish by comparing patient evolution. In order to improve the trial report, the CONSORT statement provides ...
  • Hub network design problems with profits 

    Alibeyg, Armaghan; Contreras Aguilar, Ivan; Fernández Aréizaga, Elena (2016-12-01)
    Article
    Restricted access - publisher's policy
    This paper presents a class of hub network design problems with profit-oriented objectives, which extend several families of classical hub location problems. Potential applications arise in the design of air and ground ...
