A Cost-Effective RCM Policy for Periodically Inspected Equipment Items

摘要

All maintenance tasks can be divided into two basic categories: Corrective and Preventive. Corrective maintenance (CM) is performed after an item has reached a specified failure state, while Preventive maintenance (PM) is to be applied before a failure can occur. It's well known that PM policy may successfully affect reliability and availability of an item whose failure rate increases (i.e., in the 3rd zone of the bathtub-shaped hazard curve).
