    This paper presents the p-next center problem, which aims to locate p out of n centers so as to minimize the maximum cost of allocating customers to backup centers. In this problem it is assumed that centers can fail and ...
  • The reliable p-median problem with at-facility service 

    Albareda Sambola, Maria; Hinojosa, Yolanda; Puerto Albandoz, Justo (Elsevier, 2015-09-16)
    Article

    This paper deals with a discrete facility location model where service is provided at the facility sites. It is assumed that facilities can fail and customers do not have information on failures before reaching them. As a ...
  • Fix-and-relax approaches for controlled tabular adjustment 

    Baena, Daniel; Castro Pérez, Jordi; González Alastrué, José Antonio (2015-06-01)
    Article
    Open Access
    Controlled tabular adjustment (CIA) is a relatively new protection technique for tabular data protection. CTA formulates a mixed integer linear programming problem, which is challenging for tables of moderate size. Even ...
  • Methodology for the economic optimisation of energy storage systems for frequency support in wind power plants 

    Johnstone, Lewis; Díaz González, Francisco; Gomis Bellmunt, Oriol; Corchero García, Cristina; Cruz Zambrano, Miguel (2015-01-01)
    Article
    Open Access
    This paper proposes a methodology for the economic optimisation of the sizing of Energy Storage Systems (ESSs) whilst enhancing the participation of Wind Power Plants (WPP) in network primary frequency control support. The ...
  • A biased random-key genetic algorithm for the capacitated minimum spanning tree problem 

    Ruiz Ruiz, Hector Efrain; Albareda Sambola, Maria; Fernández Aréizaga, Elena; Resende, Mauricio G. C. (2015-05)
    Article

    This paper focuses on the capacitated minimum spanning tree(CMST)problem.Given a central processor and a set of remote terminals with specified demands for traffic that must flow between the central processor and terminals,the ...
  • Stochastic model for electrical loads in Mediterranean residential building: validation and applications 

    Ortiz, Joana Aina; Guarino, Francesco; Salom Tormo, Jaume; Corchero García, Cristina; Cellura, Maurizio (2014-05)
    Article
    Open Access
    A major issue in modelling the electrical load of residential building is reproducing the variability between dwellings due to the stochastic use of different electrical equipment. In that sense and with the objective to ...
  • Renewable energies in medium-term power planning 

    Marí Tomàs, Laura; Nabona Francisco, Narcís (2015-01-01)
    Article
    Restricted access - publisher's policy
    The medium-term generation planning over a yearly horizon for generation portfolios including hydro generation and non-dispatchable renewables such as wind power and solar photovoltaic generation reveals how the penetration ...
  • Comparative study of RPSALG algorithm for convex semi-infinite programming 

    Auslander, Alfred; Ferrer Biosca, Alberto; Goberna, Miguel Ángel; López Cerdá, Marco Antonio (2014-03-01)
    Article
    Restricted access - publisher's policy
    The Remez penalty and smoothing algorithm (RPSALG) is a unified framework for penalty and smoothing methods for solving min-max convex semi-infinite programing problems, whose convergence was analyzed in a previous paper ...
  • Solving DC programs using the cutting angle method 

    Ferrer Biosca, Alberto; Bagirov, Adil; Beliakov, Gleb (2014-02)
    Article
    Open Access
    In this paper, we propose a new algorithm for global minimization of functions represented as a difference of two convex functions. The proposed method is a derivative free method and it is designed by adapting the extended ...
  • Medium-term load matching in power planning 

    Nabona Francisco, Narcís (2013-04-18)
    Article
    Restricted access - publisher's policy
    The medium-term planning for a company participating in a pure pool market can be considered under different behavioral principles: cartel, endogenous cartel with respect to hydro generation, and equilibrium. One of the ...
