Abstract: The multi-product facility location problem is an important but difficult class in facility location problems, which allows that customers have demand for different products. When solving large scale problems, commercial solvers hardly achieve high quality solutions in a reasonable time. In this paper, the general form of the uncapacitated single-source multi-product facility location problem is studied and two heuristic methods are proposed for this problem. Based on the linear relaxation optimal solution of the original problem, the two methods can provide a feasible upper bound via solving a compact problem and local search techniques, respectively. Through the theoretical analysis, it is guaranteed that these two methods can be implemented on any feasible instances. Numerical results show that the heuristic methods can significantly improve the performance of the commercial solver for solving this kind of problem.
