Periodical Inspections and Delay Replacement Model Based on Age Preventive Replacement Policy
Periodical inspections and an age-based preventive replacement（ APR） model were proposed based on a two-stage failure process for a single component system. Inspection activities were performed at regular intervals. Once the system was identified to be at defective state by inspection,a maintenance...

| Summary: | Periodical inspections and an age-based preventive replacement（ APR） model were proposed based on a two-stage failure process for a single component system. Inspection activities were performed at regular intervals. Once the system was identified to be at defective state by inspection,a maintenance decision needed to be made that whether to replace the defective system immediately or wait till the preset APR time. So a threshold was introduced into the model and called as inspection-based preventive replacement（ IPR） threshold. If the distance from the defect identification point to the APR time was longer than the threshold, a preventive replacement（ PR） action was made; otherwise PR action was to wait till the APR time. Two models were proposed and compared,and a numerical example was conducted to illustrate the applicability of the model. |
