Multi-criteria analysis with partial information about the weighting coefficients
(ELSEVIER SCIENCE BV, 1993-04-01)
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 ...

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 ...

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 management tool for indicator-supported systems: A public health service application
(ELSEVIER SCIENCE BV, 1992-01-01)
We develop a decision-making methodology for hierarchical structures. It provides different decision makers with decision-oriented information based on obtained satisfaction levels. This is specially convenient for public ...

Efficiency in Euclidean constrained location problems
(ELSEVIER SCIENCE BV, 1993-01-01)
In this note we present geometrical characterizations for the set of efficient, weakly efficient and properly efficient solutions to the multiobjective Euclidean Location problem with convex locational constraints, extending ...

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, ...
