The continuous and discrete path variance problem on trees [Article]
In this paper we consider the problem of locating path-shaped facilities on a tree minimizing the variance objective function. This kind of objective function is generally adopted in location problems which arise in the ...
Robust facility location [Article]
Let A be a nonempty finite subset of the plane representing the geographical coordinates of a set of demand points (towns, …), to be served by a facility, whose location within a given region S is sought. Assuming that the ...
Exact procedures for solving the discrete ordered median problem [Article]
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 ...
Influence analysis on discriminant coordinates [Article]
(Taylor & Francis, 2011)
Discriminant analysis (DA), particularly Discriminant Coordinates (DC), is broadly applied in the scientific literature and included in many statistical software packages. DC is used to analyze biomedical data, especially ...
Modelos de localización continua [Article]
(Sociedad Española de Matemática Aplicada, 2004)
En este trabajo se revisan tres modelos de problemas de localización continua: (1) un problema general de localización con respecto a regiones de demanda; (2) el problema de la mediana ordenada y (3) un problema ...
Finding the principal points of a random variable [Article]
(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 ...
Cooperative location games based on the minimum diameter spanning Steiner subgraph problem [Article]
In this paper we introduce and analyze new classes of cooperative games related to facility location models. The players are the customers (demand points) in the location problem and the characteristic value of a coalition ...
A biobjective method for sample allocation in stratified sampling [Article]
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. ...
Multi-group support vector machines with measurement costs a biobjective approach [Article]
Support Vector Machine has shown to have good performance in many practical classification settings. In this paper we propose, for multi-group classification, a biobjective optimization model in which we consider not only ...
