    Optimal arrangements of hyperplanes for SVM-based multiclass classification  [Article]

    Blanco Izquierdo, Víctor; Japón Sáez, Alberto; Puerto Albandoz, Justo (Springer, 2019-07)
    In this paper, we present a novel approach to construct multiclass classifiers by means of arrangements of hyperplanes. We propose different mixed integer (linear and non linear) programming formulations for the problem ...

    On location-allocation problems for dimensional facilities  [Article]

    Mallozzi, Lina; Puerto Albandoz, Justo; Rodríguez Madrena, Moisés (Springer, 2019)
    This paper deals with a bilevel approach of the location-allocation problem with dimensional facilities. We present a general model that allows us to consider very general shapes of domains for the dimensional facilities ...

    New models for the location of controversial facilities: A bilevel programming approach  [Article]

    Labbé, Martine; Leal Palazón, Marina; Puerto Albandoz, Justo (Elsevier, 2019-07)
    Motivated by recent real-life applications in Location Theory in which the location decisions generate controversy, we propose a novel bilevel location model in which, on the one hand, there is a leader that chooses among ...

    Generalized modified slash Birnbaum–Saunders distribution  [Article]

    Reyes Rocabado, Jimmy; Barranco Chamorro, Inmaculada; Gallardo Mateluna, Diego; Gómez Geraldo, Héctor (MDPI, 2018)
    In this paper, a generalization of the modified slash Birnbaum-Saunders (BS) distribution is introduced. The model is defined by using the stochastic representation of the BS distribution, where the standard normal ...

    Heliostat field cleaning scheduling for Solar Power Tower plants: a heuristic approach  [Article]

    Ashley, Thomas Ian; Carrizosa Priego, Emilio José; Fernández Cara, Enrique (Elsevier, 2019-02-01)
    Soiling of heliostat surfaces due to local climate has a direct impact on their optical efficiency and therefore a direct impact on the productivity of the Solar Power Tower plant. Cleaning techniques applied are dependent ...
