Krass, Auteur Année de publication : 2011 Article en page(s) : pp. 2002–2012 Note générale : Recherche opérationnelle Langues : Anglais (eng) Mots-clés : Cooperative  cover  Facility  location  Multiple  facilities Index. décimale : 001.424 Résumé : A family of discrete cooperative covering problems is analysed in this paper. Each facility emits a signal that decays by the distance and each demand point observes the total signal emitted by all facilities. A demand point is covered if its cumulative signal exceeds a given threshold. We wish to maximize coverage by selecting locations for p facilities from a given set of potential sites. Two other problems that can be solved by the max-cover approach are the equivalents to set covering and p-centre problems. The problems are formulated, analysed and solved on networks. Optimal and heuristic algorithms are proposed and extensive computational experiments reported.
