Contreras Aguilar, Iván; Fernández Aréizaga, Elena (Elsevier, 2011-06-16)
Article
Accés restringit per política de l'editorialThis paper presents a unified framework for the general network design problem which encompasses several classical problems involving combined location and network design decisions. In some of these problems the service ... -
GEVA: geometric variability-based approaches for identifying patterns in data
Irigoien, I.; Arenas, Concepción; Fernández Aréizaga, Elena; Mestres, Francisco (2009-10-15)
Article
Accés restringit per política de l'editorialThis paper, arising from population studies, develops clustering algorithms for identifying patterns in data. Based on the concept of geometric variability, we have developed one polythetic-divisive and three agglomerative ... -
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 obertIn 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 ... -
Heurísticas, planos secantes y optimización subgradiente para set partitioning
Barceló Bugeda, Jaime; Fernández Aréizaga, Elena (Universitat Politècnica de Barcelona. Centre de Càlcul, 1988)
Article
Accés obertEn este artículo se estudian los problemas de Set Partitioning (SP) desde una perspectiva algorítmica. El diseño de un procedimiento heurístico permite no sólo disponer de soluciones posibles para los mismos, sino también ... -

Bautista Valhondo, Joaquín; Fernández Aréizaga, Elena; González, JL; Laguna, Manuel (2005)
Text en actes de congrés
Accés obertEl presente trabajo se centra en la aplicación de un procedimiento basado en Scatter Search (SS) para resolver un problema de equilibrado de líneas de montaje. Tras una intr oducción a los denominados Assembly Line ... -
Hub network design problems with profits
Alibeyg, Armaghan; Contreras Aguilar, Iván; Fernández Aréizaga, Elena (2016-12-01)
Article
Accés obertThis 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 ... -

Lagrangean bounds for the optimum communication spanning tree problem
Contreras, I.; Fernández Aréizaga, Elena; Marín, Alfredo (Springer Verlag, 2010)
Article
Accés restringit per política de l'editorialThis paper considers the Optimum Communication Spanning Tree Problem. An integer programming formulation that yields tight LP bounds is proposed. Given that the computational effort required to obtain the LP bounds ... -
Lagrangean Duals and Exact Solution to the Capacitated p-Center Problem
Albareda Sambola, Maria; Díaz, Juan A.; Fernández Aréizaga, Elena (2006-06-12)
Article
Accés obertIn this work we study the Capacitated p-Center Problem (CpCP) and we propose an exact algorithm to solve it. We study two auxiliary problems and their relation to CpCP, and we propose two different Lagrangean duals based ... -
Location routing problems on trees
Aráoz Durand, Julián Arturo; Fernández Aréizaga, Elena; Rueda, Salvador (2019-04-30)
Article
Accés obertThis paper addresses combined location/routing problems defined on trees, where not all vertices have to be necessarily visited. A mathematical programming formulation is presented, which has the integrality property. The ... -
