Admission Policies in Loss Queueing Models with Heterogeneous Arrivals
(INST OPERATIONS RESEARCH MANAGEMENT SCIENCES, 1998-03)
In this paper we consider a loss system where the arrivals can be classified into different groups according to their arrival rate and expected service time. While the standard admission policy consists of rejecting only ...

The generalized Weber problem with expected distances
(EDP Sciences, 1995-09)
In this paper we study a generalized Weber problem where both demand locations and the facility to be located may be regions and to be assumed to be distributed according to some probability measures inside each region. A ...

Semi-obnoxious location models: a global optimization approach
(Elsevier, 1997-10-16)
In the last decades there has been an increasing interest in environmental topics. This interest has been reflected in modeling the location of obnoxious facilities, as shown by the important number of papers published ...

Multi-criteria analysis with partial information about the weighting coefficients
(ELSEVIER SCIENCE BV, 1995-03-02)
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 ...

Dominating sets for convex functions with some applications
(Springer, 1998-02)
A number of optimization methods require as a rst step the construction of a dominating set (a set containing an optimal solution) enjoying properties such as compactness or convexity. In this note we address the problem ...

Weber problems with alternative transportation systems
(ELSEVIER SCIENCE BV, 1997-02-16)
In this paper we address a planar p-facility location problem where, together with a metric induced by a gauge, there exists a series of rapid transit lines, which can be used as alternative transportation system to reduce ...

A characterization of halfspace depth
(Elsevier, 1996-07-01)
In this note we present a characterization of halfspace depth which relates it with well-known concepts of Locational Analysis. This characterization also leads to a natural extension of the concept of depth to noneuclidean ...

Bosquejo histórico de la evolución de la estadística
(Universidad de Huelva, 1996-03)
De la Ciencia Estadística se han dado muchas definiciones, yo recogeré aquí una, donde se sintetizan sus objetivos y sus fines, y así podría decirse que Estadística es la ciencia que recopila, analiza y sintetiza datos ...
