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 ...

Modelos de localización continua
(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 ...

The continuous and discrete path variance problem on trees
(Wiley, 2009-03)
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 ...

Averaging the k largest distances among n: k-centra in Banach spaces
(Elsevier, 2004-03-15)
Given a Banach space X let A ⊂ X containing at least k points. In location theory, reliability analysis, and theoretical computer science, it is useful to minimize the sum of distances from the k furthest points of A: this ...

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 ...
