An 0.828-approximation algorithm for the uncapacitated facility location problem Summary: The uncapacitated facility location problem in the following formulation is considered: $$\\max_{S\\subseteq I}Z(S)=\\sum_{j\\in J} \\max_{i\\in S... AA Ageev,MI Sviridenko - 《Discrete Applied Ma...
In the Uncapacitated Facility Location (UFL) problem, there is a fixed cost for opening a facility, and some distance matrix d that determines the cost of distributing commodities from any facility i to any consumer j . The problem is NP-hard in general and when d consists of a distance ...
Approximate hierarchical facility location and applications to the shallow steiner tree and range assignment problems (Extended abstract) The paper concerns a new variant of the hierarchical facility location problem on metric powers (HFL(beta)3 [h]), which is a multi-level uncapacitated faci...

Snyder and Daskin presented p-robust models based on two classical facility location models, the PMP (P-median problem) and UFLP (uncapacitated facility location problem). We can impose a constraint dictating that the relative regret in any scenario must be no greater than p, where p>0 is ...
Researchers formulate varied models to optimize the reliability of location decisions. But the most of such studies are not practical since the models are too ideal. In this paper, based on the classical uncapacitated fixed-charge location problem (UFLP) and some supply constraints from the ...
