Location and shape of a rectangular facility in ℝn. Convexity properties. Convexity properties
(Springer, 1998-01-01)
In this paper we address a generalization of the Weber problem, in which we seek for the center and the shape of a rectangle (the facility) minimizing the average distance to a given set (the demand-set) which is not assumed ...

A characterization of efficient points in constrained location problems with regional demand
(ELSEVIER SCIENCE BV, 1996-02-01)
In this paper we characterize the set of efficient points in the planar point-objective location problem under a convex locational constraint, when distances are measured by a strictly convex norm in ~2 and the set of ...

Maximin location: discretization not always works
(Springer, 1998-01-01)
In this note we show by means of a simple example that, if the maximin problem with (nonlinear) concave increasing utility functions is solved by inspecting the extreme points of the (generalized) Voronoi diagram (as usually ...

Undesirable facility location with minimal covering objectives
(ELSEVIER SCIENCE BV, 1999-11-19)
An undesirable facility is to be located within some feasible region of any shape in the plane or on a planar network. Population is supposed to be concentrated at a finite number n of points. Two criteria are taken into ...

El conjunto eficiente en problemas de localización con normas mixtas (L p)
(Sociedad Española de Estadística e Investigación Operativa, 1991-12-18)
En el presente trabajo establecemos una nueva aproximación a la solución del problema de localización con normas mixtas a través de lasdirecciones de proyección. Probamos que el cierre octogonal de los puntos de demanda ...

A refinement of the concept of equilibrium in multiple objective continuous games
(Real Academia de Ciencias Exactas, Físicas y Naturales, 1999)
This paper considers a perfection refinement of the concept of equihbrium for multiple objective non-zero sum games. Based on the ideas of van Damme (1991) on perturbed games and stability the concept of perfect equilibrium ...

A unified approach to network location problems
(John Wiley and Sons, 1999)
In this paper we introduce a new type of single facility location problems on networks which includes as special cases most of the classical criteria in the literature. Structural results as well as a finite dominating set ...
