Center location problems on tree graphs with subtree-shaped customers
(Elsevier, 2008-08-06)
We consider the p-center problem on tree graphs where the customers are modeled as continua subtrees. We address unweighted and weighted models as well as distances with and without addends. We prove that a relatively ...

Cooperative location games based on the minimum diameter spanning Steiner subgraph problem
(Elsevier, 2012-05)
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 ...

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 ...

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 ...
