Optimizing a Condition Based Maintenance Program with Gearbox Tooth Failure
A Condition Based Maintenance (CBM) policy is a procedure used by maintenance personnel to interpret a set of measured machine condition indicators and decide whether or not to renew a physical asset at the current moment. Traditionally CBM data interpretive policies have been obvious. For example, if the glycol measurement in an engine’s lube oil is…

Expected failure time for an item whose maintenance policy is time-based
Let Tc be the time of a cycle, tp the preventive maintenance time interval, and T the failure time. The expected life cycle Tc will be the planned maintenance time tp multiplied by the probability that planned maintenance does occur, plus the expected failure time (knowing that failure occurs before tp) multiplied by the probability that failure…

A survey of signal processing and decision technologies for CBM
Introduction Condition-based Maintenance recommends actions based on information acquired through observation and analysis. We note, moreover, that the CBM process, itself contains three sub-processes or steps: data acquisiton, signal processing, and maintenance decision making.
