The proposal assumes connectivity of instruments to report relevant features for monitoring. Also, the existence of enough historical registers with diagnosed breakdowns is required to make probabilistic models reliable and useful for predictive maintenance strategies based on them. Regular Markov models based on estimated failure and repair rates are proposed to calculate the availability of the instruments and Dynamic Bayesian Networks are proposed to model cause-effect relationships to trigger predictive maintenance services based on the influence between observed features and previously documented diagnostics" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "IEEE" , "dc.relation.isformatof": "Reproducció digital del document publicat a: http://dx.doi.org/10.1109/ETFA.2009.5347263" , "dc.relation.ispartof": "© IEEE Conference on Emerging Technologies & Factory Automation : 2009 : ETFA 2009, 2009, p. 1-4" , "dc.relation.ispartofseries": "Articles publicats (D-EEEiA)" , "dc.rights": "Tots els drets reservats" , "dc.subject": "Control predictiu" , "dc.subject": "Estadística bayesiana" , "dc.subject": "Markov, Processos de" , "dc.subject": "Medicina -- Aparells i instruments" , "dc.subject": "Bayesian statistical decision" , "dc.subject": "Markov processes" , "dc.subject": "Medical instruments and apparatus" , "dc.subject": "Predictive control" , "dc.title": "Probabilistic models to assist maintenance of multiple instruments" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/openAccess" , "dc.identifier.doi": "http://dx.doi.org/10.1109/ETFA.2009.5347263" }
