Management Mathematics for european schools
(Universidad de Zaragoza, 2004)
Beyond the topics, the Mathematics folklore says that pupils think that this field is a boring, non-practical mental exercise, far apart from daily life. This thought is influencing the entire education system and even ...

Partially ordered cooperative games: extended core and Shapley value
(Springer, 2008-02)
In this paper we analyze cooperative games whose characteristic function takes values in a partially ordered linear space. Thus, the classical solution concepts in cooperative game theory have to be revisited and redefined: ...

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 ...

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 ...

The use of relative priorities in optimizing the performance of a queueing system
(Elsevier, 2009)
Relative priorities in an n-class queueing system can reduce server and customer costs. This property is demonstrated in a single server Markovian model where the goal is to minimize a non-linear cost function of class ...

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 ...

Multifacility ordered median problems on networks: a further analysis
(Wiley, 2003)
In this paper, we address the ordered p-median problem, which includes as special cases most of the classical multifacility location problems discussed in the literature. Finite dominating sets (FDS) are known for particular ...

Policies for inventory/distribution systems: The effect of centralization vs. decentralization
(Elsevier, 2003)
This paper concerns with a multi-echelon inventory/distribution system considering one-warehouse and N-retailers. The retailers are replenished from the warehouse. We assume that the demand rate at each retailer is known. ...

Modelos de localización continua
(Sociedad Española de Matemática Aplicada, 2004)
En este trabajo se revisan tres modelos de problemas de localización continua: (1) un problema general de localización con respecto a regiones de demanda; (2) el problema de la mediana ordenada y (3) un problema ...
