Hub location problems with asymmetric allocation
I. Espejo, M. Landete, M. Leal +1
Hub location problems are central to optimizing logistics, telecommunications, and transportation networks by consolidating flows through strategically placed hubs. While existing…
A Mathematical Optimization Approach to Multisphere Support Vector Data Description
Víctor Blanco, Inmaculada Espejo, Raúl Páez +1
We present a novel mathematical optimization framework for outlier detection in multimodal datasets, extending Support Vector Data Description approaches. We provide a primal formu…
On the simultaneous location of a service facility and a rapid transit line
I. Espejo, A. M. Rodríguez-Chía
In this paper we provide a finite set of candidates to be one of the endpoints of an optimal solution for the problem of locating simultaneously a service facility and a rapid tran…
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…
