Indicadores para la medición de la cohesión social en Europa. Aplicación al caso de Andalucía
(Centro de estudios andaluces, 2012-01-01)
a amplia gama de matices que se asocian al concepto de cohesión social evidencia la dificultad de obtener una definición clara y concisa de este; más aún, es fácil encontrarlo confundido con otros tales como el bienestar ...

A computational study of a nonlinear minsum facility location problem
(PERGAMON-ELSEVIER SCIENCE LTD, 2012-01-31)
A discrete location problem with nonlinear objective is addressed. A set of p plants is to be open to serve a given set of clients. Together with the locations, the number p of facilities is also a decision variable. The ...

Cooperative location games based on the minimum diameter spanning Steiner subgraph problem
(Elsevier, 2012-05)
In this paper we introduce and analyze new classes of cooperative games related to facility location models. The players are the customers (demand points) in the location problem and the characteristic value of a coalition ...

Avoiding unfairness of Owen allocations in linear production processes
(Elsevier, 2012-07-01)
This paper deals with cooperation situations in linear production problems in which a set of goods are to be produced from a set of resources so that a certain benefit function is maximized, assuming that resources not ...

Solving Multifacility Huff Location Models on Networks Using Variable Neighborhood Search and Multi-Start Local Search Metaheuristics
(Elsevier, 2012-12-01)
We consider multifacility Huff location problems on networks. The mixed integer nonlinear optimization problem is solved using Variable Neighborhood Search and Multi-Start Local Search metaheuristics. Computational experience ...

VNS heuristic for the (r|p)-centroid problem on the plane
(Elsevier, 2012-12-01)
In the (r | p)-centroid problem, two players, called leader and follower, open facilities to service clients. We assume that clients are identified with their location on the Euclidean plane, and facilities can be opened ...

La educación y formación en materia de estadística y cartografía
(Instituto de Estadística y Cartografía de Andalucía, 2012)
La educación y la formación son dos términos polisémicos que frecuentemente son utilizados indistintamente, por ello es conveniente comenzar señalando explícitamente a qué nos estamos refiriendo cuando los usamos. Por ...

An application of integer programming to the decomposition of numerical semigroups
(Society for Industrial and Applied Mathematics, 2012)
This paper addresses the problem of decomposing a numerical semigroup into mirreducible numerical semigroups. The problem originally stated in algebraic terms is translated, introducing the so-called Kunz-coordinates, to ...

Partial Gröbner bases for multiobjective integer linear optimization
(Society for Industrial and Applied Mathematics, 2012)
This paper presents a new methodology for solving multiobjective integer linear programs (MOILP) using tools from algebraic geometry. We introduce the concept of partial Gr¨obner basis for a family of multiobjective programs ...

Gaussian variable neighborhood search for continuous optimization
(PERGAMON-ELSEVIER SCIENCE LTD, 2012-01-01)
Variable Neighborhood Search (VNS) has shown to be a powerful tool for solving both discrete and box-constrained continuous optimization problems. In this note we extend the methodology by allowing also to address unconstrained ...
