Upgrading edges in the maximal covering location problem
Marta Baldomero-Naranjo, Jörg Kalcsics, Alfredo Marín +1
We study the upgrading version of the maximal covering location problem with edge length modifications on networks. This problem aims at locating p facilities on the vertices (of t…
Multi-period stochastic covering location problems: Modeling framework and solution approach
Alfredo Marín, Luisa I. Martínez-Merino, Antonio M. Rodríguez-Chía +1
This paper introduces a very general discrete covering location model that accounts for uncertainty and time-dependent aspects. A MILP formulation is proposed for the problem. Afte…
The soft-margin Support Vector Machine with ordered weighted average
Alfredo Marín, Luisa I. Martínez-Merino, Justo Puerto +1
This paper deals with an extension of the Support Vector Machine (SVM) for classification problems where, in addition to maximize the margin, i.e., the width of strip defined by th…
Upgrading nodes in tree-shaped hub location
Víctor Blanco, Alfredo Marín
In this paper, we introduce the Tree of Hubs Location Problem with Upgrading, a mixture of the Tree of Hubs Location Problem, presented by Contreras et. al (2010), and the Minimum…
A comparison of formulations and solution methods for the Minimum-Envy Location Problem. Additional results
Inmaculada Espejo, Alfredo Marin, Justo Puerto +1
We consider a discrete facility location problem with a new form of equity criterion. The model discussed in the paper analyzes the case where demand points only have strict prefer…
