The paper considers renewable (or replaceable) units, assemblies, and similar equipment items with increasing failure rate whose gradual aging is due to depletion of some physical property or material. These items can be periodically inspected and, if necessary, restored.
The best maintenance strategy for such items should be based on the preventive condition-directed concept.
