Multi-criteria analysis with partial information about the weighting coefficients
(ELSEVIER SCIENCE BV, 1995-03-02)
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 ...

Generalizations of nondifferentiable convex functions and some characterizations
(1991)
In this paper we generalize the convex functions, defining the concept of preconvex function and we study some characterizations by intervals, some characterizations by polytopes, some characterizations by level sets, ...

Dominating sets for convex functions with some applications
(Springer, 1998-02)
A number of optimization methods require as a rst step the construction of a dominating set (a set containing an optimal solution) enjoying properties such as compactness or convexity. In this note we address the problem ...

Weber problems with alternative transportation systems
(ELSEVIER SCIENCE BV, 1997-02-16)
In this paper we address a planar p-facility location problem where, together with a metric induced by a gauge, there exists a series of rapid transit lines, which can be used as alternative transportation system to reduce ...

A characterization of halfspace depth
(Elsevier, 1996-07-01)
In this note we present a characterization of halfspace depth which relates it with well-known concepts of Locational Analysis. This characterization also leads to a natural extension of the concept of depth to noneuclidean ...

Bosquejo histórico de la evolución de la estadística
(Universidad de Huelva, 1996-03)
De la Ciencia Estadística se han dado muchas definiciones, yo recogeré aquí una, donde se sintetizan sus objetivos y sus fines, y así podría decirse que Estadística es la ciencia que recopila, analiza y sintetiza datos ...

Combining minsum and minmax: A goal programming approach
(INST OPERATIONS RESEARCH MANAGEMENT SCIENCES, 1999-07-01)
A number of methods for multiple-objective optimization problems (MOP) give as solution to MOP the set of optimal solutions for some single-objective optimization problems associated with it. Well-known examples of these ...
