Two-group classification via a biobjective margin maximization model
(ELSEVIER SCIENCE BV, 2006-09-16)
In this paper we propose a biobjective model for two-group classification via margin maximization, in which the margins in both classes are simultaneously maximized. The set of Pareto-optimal solutions is described, yielding ...

Some relations between variational-like inequalities and efficient solutions of certain nonsmooth optimization problems
(Hindawi, 2006)
We study the equivalence between the solutions of the variational-like inequality problem and the solutions of certain nonsmooth and nonconvex vectorial optimization problem.

An exact global optimization method for deriving weights from pairwise comparison matrices
(Springer, 2006-09-06)
Some multiple-criteria decision making methods rank actions by associating weights to the different criteria or actions, which are pairwise compared via a positive reciprocal matrix A. There is a vast literature on proposals ...

Exact procedures for solving the discrete ordered median problem
(Elsevier, 2006-11)
The Discrete Ordered Median Problem (DOMP) generalizes classical discrete location problems, such as the N-median, N-center and Uncapacitated Facility Location problems. It was introduced by Nickel [S. Nickel. Discrete ...

La Estadística Pública como apoyo a la investigación
(Asociación Española de Ciencia Regional, 2006)
Cualquier estudio o investigación sobre temas económicos, sociales y, por supuesto territoriales, requiere disponer y utilizar datos e información estadística. El artículo examina el estado actual de la producción de ...

The bi-criteria doubly weighted center-median path problem on a tree
(Wiley, 2006-07)
Given a tree network T with n nodes, let PL be the subset of all discrete paths whose length is bounded above by a prespecified value L. We consider the location of a path-shaped facility P ∈ PL, where customers are represented ...

A biobjective method for sample allocation in stratified sampling
(ELSEVIER SCIENCE BV, 2006-02-16)
The two main and contradicting criteria guiding sampling design are accuracy of estimators and sampling costs. In stratified random sampling, the sample size must be allocated to strata in order to optimize both objectives. ...

Deriving Weights in Multiple-Criteria Decision Making with Support Vector Machines
(Springer, 2006-01-01)
A key problem in Multiple-Criteria Decision Making is how to measure the importance of the different criteria when just a partial preference relation among actions is given. In this note we address the problem of ...

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 ...
