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 ...

New results on minimax regret single facility ordered median location problems on networks
(Springer, 2007)
We consider the single facility ordered median location problem with uncertainty in the parameters (weights) defining the objective function. We study two cases. In the first case the uncertain weights belong to a region ...

Multiobjective solution of the uncapacitated plant location problem
(Elsevier, 2003)
In this paper we consider the discrete multiobjective uncapacitated plant location problem. We present an exact and an approximate approach to obtain the set of non-dominated solutions. The two approaches resort to dynamic ...

Optimal Positioning of a Mobile Service Unit on a Line
(Springer, 2002-03-01)
In this paper we address the problem of locating a mobile response unit when demand is distributed according to a random variable on a line. Properties are proven which reduce the problem to locating a non-mobile facility, ...

Production-inventory games: A new class of totally balanced combinatorial optimization games
(Elsevier, 2009)
In this paper we introduce a new class of cooperative games that arise from production-inventory problems. Several agents have to cover their demand over a finite time horizon and shortages are allowed. Each agent has its ...

Multi-criteria minimum cost spanning tree games
(Elsevier, 2004)
The minimum cost spanning tree game (mcst-game) is a well-known model within operations research games that has been widely studied in the literature. In this paper we introduce the multi-criteria version of the mcst-game ...
