Revisiting transportation problems under Monge costs with applications to the Discrete Ordered Median Problem
Stefan Nickel, Justo Puerto, Simon Ramoser +1
We investigate the classical Hitchcock-Koopmans Transportation Problem under the assumption that the cost matrix satisfies the Monge property. In this setting, we derive compact fo…
Linear, nested, and quadratic ordered measures: Computation and incorporation into optimization problems
Victor Blanco, Miguel A. Pozo, Justo Puerto +1
In this paper we address a unified mathematical optimization framework to compute a wide range of measures used in most operations research and data science contexts. The goal is t…
A fresh view on Least Quantile of Squares Regression based on new optimization approaches
Justo Puerto, Alberto Torrejon
Regression analysis is an important instrument to determine the effect of the explanatory variables on response variables. When outliers and bias errors are present, the standard w…
Proceedings of the XIII International Workshop on Locational Analysis and Related Problems
Marta Baldomero-Naranjo, Ricardo Gázquez, Miguel Martínez-Antón +6
The topics of interest are location analysis and related problems. This includes location models, networks, transportation, logistics, exact and heuristic solution methods, and com…
Proceedings of the XII International Workshop on Locational Analysis and Related Problems
Marta Baldomero-Naranjo, Víctor Blanco, Sergio García +6
The International Workshop on Locational Analysis and Related Problems will take place during September 7-8, 2023 in Edinburgh (United Kingdom). It is organized by the Spanish Loca…
An extended version of the Ordered Median Tree Location Problem including appendices and detailed computational results
Miguel A. Pozo, Justo Puerto, Alberto Torrejon
In this paper, we propose the Ordered Median Tree Location Problem (OMT). The OMT is a single-allocation facility location problem where p facilities must be placed on a network co…
