A Plug-and-Play Module for Assessing Real-Time Mission Readiness Using Subsystem Health and Interactions

Impact Technologies, LLC., in collaboration with Life Cycle Engineering, Inc., proposes to develop and demonstrate mission readiness assessment techniques using component and subsystem health indexes in an open systems architecture (OSA). The proposed work will utilize mission requirements, component health states, and potentially available models to develop a plug-and-play software module that can be used to assess system mission readiness in real-time. The development will include algorithms to account for subsystem interaction and relate independent subsystem health indicators to overall system readiness. Prognostics will also be included to predict future readiness levels for specific missions. This information will ultimately be utilized for decision support of Navy ship systems. Specifically, the core innovations of the proposed project include: 1) the use of gray scale health to assess mission readiness; 2) fusion of multiple independent health state indicators to determine overall system health; and 3) development of a prognostics approach that accounts for the effects of fault propagation between interconnected subsystems by defining propagation paths and adjusting failure rates accordingly.
