%0 Journal Article %T APPLICATION OF MARKOV CHAIN FOR MONITORING THE BEARING ROLLER DEGRADATION %A BOUZAOUIT A. %A BENNIS O. %A BENOTMANE Z. %J Journal of Engineering Studies and Research %D 2011 %I Vasile Alecsandri University of Bacau %X The present study is an assessment to assign reference 2309CK bearings installed on a centrifugal fan from States expressing a (probability) level of degradation from "Good" to "Degraded". We seek to model the dynamics of change of state with a homogeneous Markov chain. In addition, it is possible to use the transition matrix associated to Markov chain to an operation analysis for the determination of the rotating machine reliability. The proposed model (transition matrix or graphic form) allows to know the turnover probability throughout life degradation. %K conditional maintenance %K bearings %K Markov chain %K statistical analysis %U http://pubs.ub.ro/?pg=revues&rev=jesr&num=201101&vol=17&aid=3360
