Pareto-Optimality in Linear Regression
(Academic Press Inc. Elsevier Science, 2002-05-25)
In this paper the linear regression problem is studied in the context of vector optimization theory. The set of Pareto-optimal solutions is represented as the set of optimal solutions to certain optimization problems, and ...

A fractional model for locating semi-desirable facilities on networks
(ELSEVIER SCIENCE BV, 2002-01-01)
In this paper, we address the problem of locating a series of facilities on a network maximizing the average distance to population centers (assumed to be distributed in the plane) per unit transportation cost (a function ...

Finding the principal points of a random variable
(EDP Sciences, 2001)
The p-principal points of a random variable X with finite second moment are those p points in R minimizing the expected squared distance from X to the closest point. Although the determination of principal points involves ...

Finding GM-estimators with global optimization techniques
(Springer, 2001-01-01)
In this note we address the problem of finding the GM-estimator for the location parameter of a univariate random variable. When this problem is non-convex but d.c. one can use a standard covering method, which, in the ...

Inferring efficient weights from pairwise comparison matrices
(Springer, 2006-10)
Several multi-criteria-decision-making methodologies assume the existence of weights associated with the different criteria, reflecting their relative importance.One of the most popular ways to infer such weights is the ...
