Traditionally, predictive maintenance is used solely as a maintenance management tool. In most cases, this use is limited to preventing failures. Although this function is important, predictive maintenance can provide substantially more beneﬁts by expanding the scope or mission of the program.
As a maintenance management tool, predictive maintenance can and should be used as a maintenance optimization tool. The program’s focus should be on:
1) Eliminating unnecessary downtime, both scheduled and unscheduled
2) Eliminating unnecessary preventive and corrective maintenance tasks
3) Extending the useful life of critical systems
4) Reducing the total life-cycle cost of these systems
