A Novel Readiness Model

The current readiness model focuses solely on the maintenance support without considering the spare parts supply, and usually the model itself can even overestimate the actual readiness. The readiness cannot be replaced with the operational availability due to their different targets, operational and maintenance profiles and related parameters. In this paper, a new readiness model with full consideration of both the maintenance support and the spare parts supply is proposed, which is more in line with the meaning of readiness and shall be more useful for the trade-off of reliability, maintainability and spare parts supportability, the reduction of the life cycle cost and the optimization of engineering design.
