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 ...

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 ...

A note on the optimal positioning of service units
(INST OPERATIONS RESEARCH MANAGEMENT SCIENCES, 1998-02-01)
In this paper we address the problem of locating p mobile service units in an n-dimensional space minimizing the expected response time. It is shown that an optimal solution to the problem is a degenerate distribution for ...

The Weber problem with regional demand
(ELSEVIER SCIENCE BV, 1996-12-27)
This paper is devoted to the study of the Regional Weber Problem, an extension of the Weber problem which allows the demand not be concentrated onto a finite set of points. The most serious drawback of this formulation, ...
