A method of modeling a mission system. The system is represented as a plurality of architectural components. At least some of the architectural components are configured with availability characteristics to obtain a model of the system. The model is implemented to assess availability in the mission system. The model may be implemented to perform tradeoff decisions for each individual component and interrelated components. Availability can be assessed for the system, given all of the tradeoffs.
