Issues and methods of relating program requirements to PHM requirements and allocation of PHM requirements to lower system levels are discussed as alternatives to technology-driven approaches. This paper focuses on evaluating program requirements for improving reliability for military systems with a required maintenance free operating period. Reliability improvements are related to PHM attributes, which are condensed to two primary attributes: coverage and inefficiency. Methods of allocation of higher level PHM requirements to lower level requirements are examined, focusing on a normalized weighting approach. An alternative approach beginning with coverage estimates is also examined. A discrete-event simulation model is developed and exercised to confirm analytical results.
