A characterization of the multivariate excess wealth ordering
(Elsevier, 2011-11)
In this paper, some new properties of the upper-corrected orthant of a random vector are proved. The univariate rightspread or excess wealth function, introduced by Fernández-Ponce et al. (1996), is extended to multivariate ...

On a new NBUE property in multivariate sense: an application
(Elsevier, 2011-12-01)
Multivariate lifetime data frequently arise so it is important to consider different multivariate distributions that could be used to model aging concepts. The generalization of univariate versions has two main problems. One ...

Locating a competitive facility in the plane with a robustness criterion
(Elsevier, 2011-11-16)
A new continuous location model is presented and embedded in the literature on robustness in facility location. The multimodality of the model is investigated, and a branch and bound method based on dc optimization is ...

A cooperative location game based on the 1-center location problem
(Elsevier, 2011-10-16)
In this paper we introduce and analyze new classes of cooperative games related to facility location models defined on general metric spaces. The players are the customers (demand points) in the location problem and the ...

A global optimization procedure for the location of a median line in the three-dimensional space
(ELSEVIER SCIENCE BV, 2011-06-01)
A global optimization procedure is proposed to find a line in the Euclidean three-dimensional space which minimizes the sum of distances to a given finite set of three-dimensional data points. Although we are using similar ...
