    Dai, Guangming; Chen, Xiaoyu; Wang, Maocai; Fernández Aréizaga, Elena; Nguyen, Tuan Nam; Reinelt, Gerhard (2017-11-01)
    Article
    Accés obert
    This paper studies the problem of analyzing multisatellite constellations with respect to their coverage capacity of areas on Earth’s surface. The geometric configuration of constellation projection points on Earth’s surface ...

  • The shared customer collaboration vehicle routing problem 

    Fernández Aréizaga, Elena; Roca Riu, Mireia; Speranza, M. Grazia (Elsevier, 2018-03-16)
    Article
    Accés restringit per política de l'editorial
    This paper introduces a new vehicle routing problem that arises in an urban area where several carriers operate and some of their customers have demand of service for more than one carrier. The problem, called Shared ...

  • The generalized arc routing problem 

    Araoz Durand, Julian Arturo; Fernández Aréizaga, Elena; Franquesa, Carles (Springer, 2017-10)
    Article
    Accés restringit per política de l'editorial
    This paper focuses on the generalized arc routing problem. This problem is stated on an undirected graph in which some clusters are defined as pairwise-disjoint connected subgraphs, and a route is sought that traverses at ...

  • A branch-and-price algorithm for the Aperiodic Multi-Period Service Scheduling Problem 

    Fernández Aréizaga, Elena; Kalcsics, Jörg; Núñez del Toro, Alma Cristina (Elsevier, 2017-12-16)
    Article
    Accés restringit per política de l'editorial
    This paper considers the multi-period service scheduling problem with an aperiodic service policy. In this problem, a set of customers who periodically require service over a finite time horizon is given. To satisfy the ...

  • Multi-depot rural postman problems 

    Fernández Aréizaga, Elena; Rodríguez Pereira, Jessica (Springer, 2017-07-01)
    Article
    Accés restringit per política de l'editorial
    This paper studies multi-depot rural postman problems on an undirected graph. These problems extend the well-known undirected rural postman problem to the case where there are several depots instead of just one. Linear ...

  • Minimum Spanning Trees with neighborhoods: mathematical programming formulations and solution methods 

    Blanco, Víctor; Fernández Aréizaga, Elena; Puerto Albandoz, Justo (Elsevier, 2017-11-01)
    Article
    Accés restringit per política de l'editorial
    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
    Accés obert
    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 ...

  • Ordered Weighted Average optimization in Multiobjective Spanning Tree Problem 

    Fernández Aréizaga, Elena; Pozo, Miguel Angel; Puerto Albandoz, Justo; Scozzari, Andre (Elsevier, 2017-08-01)
    Article
    Accés obert
    Rework adversely impacts the performance of building projects. In this study, data were analyzed from 788 construction incidents in 40 Spanish building projects to determine the effects of project and managerial characteristics ...

  • The flexible periodic vehicle routing problem 

    Archetti, C; Fernández Aréizaga, Elena; Huerta Muñoz, Diana Lucia (2017-09)
    Article
    Accés restringit per política de l'editorial
    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
    Accés obert
    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
    Accés obert
    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
    Accés obert
    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, ...
