The continuous and discrete path variance problem on trees
(Wiley, 2009-03)
In this paper we consider the problem of locating path-shaped facilities on a tree minimizing the variance objective function. This kind of objective function is generally adopted in location problems which arise in the ...

Single facility location problems with unbounded unit balls
(Springer Verlag (Germany), 2003)
Tesis Doctoral
Análisis cooperativo de cadenas de distribución
(2007-05-29)
En esta tesis se estudia la posible cooperación en procesos de decisión en los que intervienen varios agentes. Las principales contribuciones de este trabajo son:- Exten sión del concepto de solución de Owen para juegos ...

A flexible approach to location problems
(Springer, 2000-02)
When dealing with location problems we are usually given a set of existing facilities and we are looking for the location of one or several new facilities. In the classical approaches weights are assigned to existing ...

The multiscenario lot size problem with concave costs
(Elsevier, 2004)
The dynamic single-facility single-item lot size problem is addressed. The finite planning horizon is divided into several time periods. Although the total demand is assumed to be a fixed value, the distribution of this ...

Soluciones algebraicas a la resolución de problemas multiobjetivo discretos Algebraic solutions for solving discrete multiobjective problems
(2009)
Esta tesis doctoral estudia algunos de los aspectos algebraicos de la optimización multiobjetivo lineal y polinomial. Primeramente, en el Capítulo 1 se introducen los conceptos básicos necesarios para el desarrollo de los ...

Production-inventory games: A new class of totally balanced combinatorial optimization games
(Elsevier, 2009)
In this paper we introduce a new class of cooperative games that arise from production-inventory problems. Several agents have to cover their demand over a finite time horizon and shortages are allowed. Each agent has its ...

Exact procedures for solving the discrete ordered median problem
(Elsevier, 2006-11)
The Discrete Ordered Median Problem (DOMP) generalizes classical discrete location problems, such as the N-median, N-center and Uncapacitated Facility Location problems. It was introduced by Nickel [S. Nickel. Discrete ...

On the exponential cardinality of FDS for the ordered p-median problem
(Elsevier, 2005)
We study finite dominating sets (FDS) for the ordered median problem. This kind of problems allows to deal simultaneously with a large number of models. We show that there is no valid polynomial size FDS for the general ...
