RESUMO

We present here a Flow/Multicommodity Flow model for Transportation and Production Planning problems. We deal with this model through Lagrangean Relaxation and Hierarchical Decomposition techniques, which involve the resolution of a specific flow with least integral cost problem. We propose and test several heuristic schemes for this specific problem and conclude by discussing some particular situations.
