We study multi-level uncapacitated p-location problems, a general class of facility location problems. We use a combinatorial representation of the general problem where the objective function satisfies the submodularity property, and we exploit this characterization to derive worst-case bounds for a greedy heuristic and introduce a mixed integer linear programming formulation for the problem. Some computational results are summarized in the presentation.
