Definition of RMS Tasks: Definition of RMS Tasks Failure Logic Modeling: Combines the FMEA and related analysis in one step with the development of the failure logic (e.g., fault tree, event tree, etc.). Reliability Modeling: The quantification of the Failure Logic Model through data fitting and other techniques. Reliability Analysis: Execution of the quantified Failure Logic Model (Monte Carlo simulation) to estimate reliability figures of merit. Reliability-Centered Maintenance Analysis: Transforming failure and reliability data into a set of scheduled maintenance actions/ Maintenance Downtime Modeling: Developing a time-sequenced ordering of maintenance and support actions. Maintainability Modeling: Developing models to estimate expected durations of the maintenance and support actions in the Maintenance Downtime Model. Downtime Analysis: Executing the Maintenance Downtime Model to determine the availability (turnaround time) for a Launch Vehicle Architecture. Launch Availability Analysis: Combing the output of Downtime Analysis, Start-up Reliability, and Weather Robustness of a Launch Vehicle Architecture to estimate the architecture’s Launch Availability. Maintenance Task Analysis: Decomposing maintenance actions in the Maintenance Downtime Model to the level of fidelity required. Maintenance Packaging Analysis: Ordering the maintenance and support actions in the Maintenance Downtime Model to best achieve launch vehicle availability within cost constraints. Supportability Modeling: Developing support resource estimating relationships for the maintenance and support actions in the Maintenance Downtime Model. Supportability Analysis: Executing the Maintenance Downtime Model to estimate the maintenance support resource requirements of a Launch Vehicle architecture. Trades/Special Studies: RMS modeling and analysis necessary per trade/study
