Although condition-based maintenance allows for more effectively planned maintenance actions, its relative performance depends on the behavior of the deterioration process. The objective of this paper is to develop a clustering model of maintenance activities and analyze the effect of perfect, imperfect, and hybrid maintenance on the cost. We consider a two-component system that experiences three degradation states before a complete failure. The components are equipped with a monitoring system that signals before each state change, on which our clustering is based. Actually, we have three types of clustering aiming at cost minimization. The results provide a general insight into when and how the activities are clustered and what kind of maintenance is selected such that the cost is minimized. Moreover, The results showed that clustering with a more degree of the clusters is more appropriate and produced cost savings about 70%, if the fixed cost exceeds a certain amount.}, keywords = {Imperfect maintenance,Condition-based Maintenance,Clustering,Condition Monitoring,Prediction signal}, url = {http://www.ijrrs.com/article_119346.html}, eprint = {http://www.ijrrs.com/article_119346_07fcdf0a1d293bbbc235276d3fdc0968.pdf} }
