Condition based maintenance in the context of opportunistic maintenance [PDF]
International Journal of Production Research, 2012 Condition based maintenance (CBM) uses the operating condition of a component to predict a failure event. Compared to age based replacement (ABR), CBM usually results in higher availability and lower maintenance costs, since it tries to prevent unplanned downtime and avoid unnecessary preventive maintenance activities for a component.
