N., Auteur ; Narendran, T. T., Auteur Année de publication : 2011 Article en page(s) : pp. 722–728 Note générale : Recherche opérationnelle Langues : Anglais (eng) Mots-clés : Military convoys Conflicts Scheduling Lagrangean relaxation Heuristics Index. décimale : 001.424 Résumé : The problem of routing military convoys between specific origin and destination pairs is known as convoy movement problem (CMP). In this study, we consider an existing mathematical model of CMP and propose a lower bounding procedure based on Lagrangean Relaxation. The robustness of the proposed procedure is evaluated on a variety of test problem instances. Encouraging results are obtained.
