Center location problems on tree graphs with subtree-shaped customers
(Elsevier, 2008-08-06)
We consider the p-center problem on tree graphs where the customers are modeled as continua subtrees. We address unweighted and weighted models as well as distances with and without addends. We prove that a relatively ...

Multiobjective solution of the uncapacitated plant location problem
(Elsevier, 2003)
In this paper we consider the discrete multiobjective uncapacitated plant location problem. We present an exact and an approximate approach to obtain the set of non-dominated solutions. The two approaches resort to dynamic ...

Multi-criteria analysis with partial information about the weighting coefficients
(ELSEVIER SCIENCE BV, 1993-04-01)
In this paper we address the problem of ranking a set of alternatives with partial information about the weighting coefficients. We introduce a family of quasiorders that are easily interpretable and manageable, which ...

A modeling framework for ordered weighted average combinatorial optimization
(Elsevier, 2014-05)
Multiobjective combinatorial optimization deals with problems considering more than one viewpoint or scenario. The problem of aggregating multiple criteria to obtain a globalizing objective function is of special interest ...

Optimal arrangements of hyperplanes for SVM-based multiclass classification
(Springer, 2019-07)
In this paper, we present a novel approach to construct multiclass classifiers by means of arrangements of hyperplanes. We propose different mixed integer (linear and non linear) programming formulations for the problem ...

Mathematical programming formulations for the efficient solution of the k-sum approval voting problem
(Elsevier, 2018-10)
In this paper we address the problem of electing a committee among a set of m candidates and on the basis of the preferences of a set of n voters. We consider the approval voting method in which each voter can approve as ...

Ordered median hub location problems with capacity constraints
(Elsevier, 2015-06-15)
The Single Allocation Ordered Median Hub Location problem is a recent hub model introduced in [36] J. Puerto, A.B. Ramos, and A.M. Rodríguez-Chía. Single-Allocation Ordered Median Hub Location Problems. Computers and ...

Juegos con pagos vectoriales
(, 2002)
En este trabajo analizamos los diferentes aspectos de la teoría de juego con pagos vectoriales. El carácter vectorial de los pagos hace necesario revisar y redefinir los conceptos de la teoría de juegos clásica. Destacamos ...

Dynamically second-preferred p-center problem
(Elsevier, 2023)
This paper deals with the Dynamically Second-preferred p-center Problem (DSpP). In this problem, cus- tomers’ preferences and subsets of sites that each customer is willing to accept as service centers are taken into ...

Continuous multifacility ordered median location problems
(Elsevier, 2016-04-01)
In this paper we propose a general methodology for solving a broad class of continuous, multifacility location problems, in any dimension and with ℓτ -norms proposing two different methodologies: 1) by a new second order ...
