On the exponential cardinality of FDS for the ordered p-median problem [Article]
We study finite dominating sets (FDS) for the ordered median problem. This kind of problems allows to deal simultaneously with a large number of models. We show that there is no valid polynomial size FDS for the general ...
New results on minimax regret single facility ordered median location problems on networks [Article]
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 ...
