Les activités de maintenance ont subi de profondes évolutions, suite à l'arrivée des Technologies d'Information et de Communication (TIC). Nous proposons dans cet article une démarche d'évaluation des performances d'une solution de e-maintenance. L'étude est centrée sur le déploiement des ressources de maintenance, plus particulièrement sur les ressources immatérielles (connaissances et compétences) rendues accessibles par le eservice. Nous modélisons d'abord les situations étudiées dans un contexte multiacteur et multimodèle. Nous proposons ensuite une approche de caractérisation des ressourcesimmatérielles en intégrant un aspect quantitatif et un aspect qualitatif. Enfin, avant de conclure, nous donnons une première exploitation des indicateurs clefs au niveau de la répartition des connaissances nécessaires à l'obtention d'une intervention de qualité.
This paper deals with the collaborative decision making induced or facilitated by Information and Communication Technologies (ICTs) and their impact on decisional systems. After presenting the problematic, we analyse the collaborative decision making and define the concepts related to the conditions and forms of collaborative work. Then, we explain the mechanisms of collaborative decision making with the specifications and general conditions of collaboration using the modelling formalism of the GRAI method. Each specification associated to the reorganisation of the decisional system caused by the collaboration is set to the notion of decision-making centre. Finally, we apply this approach to the e-maintenance field, strongly penetrated by the ICTs, where collaborations are usual. We show that the identified specifications allow improving the definition and the management of collaboration in e-maintenance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
