Constraint relaxation for the Discrete Ordered Median Problem
Luisa I. Martínez-Merino, Diego Ponce, Justo Puerto
This paper compares different exact approaches to solve the Discrete Ordered Median Problem (DOMP). In recent years, DOMP has been formulated using set packing constraints giving r…
Network Flow based approaches for the Pipelines Routing Problem in Naval Design
Víctor Blanco, Gabriel González, Yolanda Hinojosa +3
In this paper we propose a general methodology for the optimal automatic routing of spatial pipelines motivated by a recent collaboration with Ghenova, a leading Naval Engineering…
A Branch-and-Price approach for the Continuous Multifacility Monotone Ordered Median Problem
Víctor Blanco, Ricardo Gázquez, Diego Ponce +1
In this paper, we address the Continuous Multifacility Monotone Ordered Median Problem. This problem minimizes a monotone ordered weighted median function of the distances between…
A Branch-and-price procedure for clustering data that are graph connected
Stefano Benati, Diego Ponce, Justo Puerto +1
This paper studies the Graph-Connected Clique-Partitioning Problem (GCCP), a clustering optimization model in which units are characterized by both individual and relational data.…
Proceedings of the X International Workshop on Locational Analysis and Related Problems
Maria Albareda-Sambola, Marta Baldomero-Naranjo, Luisa I. Martínez-Merino +4
The International Workshop on Locational Analysis and Related Problems will take place during January 23-24, 2020 in Seville (Spain). It is organized by the Spanish Location Networ…
On the multisource hyperplanes location problem to fitting set of points
Víctor Blanco, Alberto Japón, Diego Ponce +1
In this paper we study the problem of locating a given number of hyperplanes minimizing an objective function of the closest distances from a set of points. We propose a general fr…
Portfolio problems with two levels decision-makers: Optimal portfolio selection with pricing decisions on transaction costs. Extended version and complete risk profiles analysis
Marina Leal, Diego Ponce, Justo Puerto
This paper presents novel bilevel leader-follower portfolio selection problems in which the financial intermediary becomes a decision-maker. This financial intermediary decides on…
Mathematical Programming formulations for the efficient solution of the -sum approval voting problem
Diego Ponce, Justo Puerto, Federica Ricca +1
In this paper we address the problem of electing a committee among a set of candidates and on the basis of the preferences of a set of voters. We consider the approval voti…
Continuous Location under Refraction
Victor Blanco, Justo Puerto, Diego Ponce
In this paper we address the problem of locating a new facility on a -dimensional space when the distance measure (- or polyhedral-norms) is different at each one of the…
