Génération d'indicateurs de maintenance par une approche semi-paramétrique et par une approche markovienne
Résumé
Today, maintenance strategies and their analyses remain a worrying problem for companies. Socio economic stakes depending on competitiveness of each strategy are even more linked to activity and quality of maintenance interventions. A series of specific events can eventually warn the expert of animminent breakdown. Our study aims at understanding this "signature" thanks to an hidden Markov model. On that purpose, two strategies on damage level estimation of maintained system are proposed to expert. The first one consists in using of non parametric degradation laws. The second one consists in using of an markovian approach.
