Abstract
We developed a new practical optimization method that gives approximate solutions for large-scale real instances of the Uncapacitated Facility Location Problem. The optimization consists of two steps: application of the Greedy — Interchange heuristic using a small subset of warehouse candidates, and application of the newly developed heuristic named Balloon Search that takes account of all warehouse candidates. Our experiments on the spare parts logistics of a Japanese manufacturing company with 6,000 customers and 780,000 warehouse candidates led us to conclude that the Greedy heuristic improved the total cost by 9% – 11%, that the Interchange heuristic improved the total cost by an additional 0.5% – 1.5%, and that the Balloon Search improved it by a further 0.5% – 1.5%.
