Prognostics and Health Management (PHM) enabled maintenance is considered to be the most recent phase in the evolution of maintenance paradigms. It enables outcome-based contracts, dynamic warranties, maintenance-optimized availability, among other benefits. PHM enables flexibility whereby the decision-maker can choose from a set of options arising after prognostic indication in order to manage its health. This paper proposes a methodology to determine a dynamic maintenance threshold for a fleet or for individual systems in order to meet an availability requirement. Placing a dynamic threshold for maintenance allows the maximization of returns from assets and accounts for multiple sources of uncertainty.
