| Abstract: | A decomposition algorithm for a production and distribution problem allows finding a very good suboptimal solution for an 85 000 variable model with 2600 0–1 variables. A global reoptimization process of the continuous part improves the final solution. Annual savings over 3.7% of variable costs and a reasonable CPU time are obtained. A user-oriented program (generation, solution and report) is developed. |
