Considerations in the use of optimal preventive maintenance policies

摘要

AbstractDesigning products which require maintenance always involves compromises between reliability and maintainability. Both scheduled and preventive maintenance (PM) should be considered in the design phases of a product so that the design can include features to ease the maintenance task. In addition, many design decisions based on Failure Modes and Effects Criticality Analysis (FMECA), Pareto criticality rankings, etc., could and should be strongly influenced by the potential for using preventive maintenance. A component that has a major negative impact on system reliability (because of its life distribution)could become much less consequentialif appropriate PM policies are implemented. This paper describes the use of an easy‐to‐implement analysis procedure to assist adesignerorsystems analystin making the reliability/maintainability trade
