Ingolfsson, Auteur ; G. Laporte, Auteur Année de publication : 2010 Article en page(s) : pp. 543–550 Note générale : Recherche opérationnelle Langues : Anglais (eng) Mots-clés : Ambulance  location  Shift  scheduling  Tabu  search  Integer  programming Index. décimale : 001.424 Résumé : This paper addresses the problem of scheduling ambulance crews in order to maximize the coverage throughout a planning horizon. The problem includes the subproblem of locating ambulances to maximize expected coverage with probabilistic response times, for which a tabu search algorithm is developed. The proposed tabu search algorithm is empirically shown to outperform previous approaches for this subproblem. Two integer programming models that use the output of the tabu search algorithm are constructed for the main problem. Computational experiments with real data are conducted. A comparison of the results of the models is presented.
