Fault Management Analysis Tool For Model Centric Systems Engineering

This proposal responds to the need for new technologies to effectively manage and streamline complex fault management (FM) systems, enable rapid diagnostic model generation and validation, and provide tools to perform FM analyses and trades e.g., fault containment regions (FCRs), FM model validation, sensor placement, and telemetry review for ground operations. During Phase II-E, Okean Solutions proposes to tighten and enhance the integration of their model-based fault management tool/system, called MONSID, with JPLs Computer Aided Engineering for Systems Architecture (CAESAR) platform. MONSID-CAESAR interoperability will be improved by enabling model translation from MONSID to CAESAR. The combined capability will advance the practice of FM to ultimately decrease manually intensive and error-prone tasks and schedule costs while ensuring FM system robustness and appropriateness. The enhanced adapter will be applied to a MONSID model of the Soil Moisture Active Passive (SMAP) spacecraft. The main application is FM analyses as well as design and software development. Phase II-E lays the foundation for additional uses in Integration and Test (IT) and operational phases to update onboard FM models and in support of recovery operations. By integrating with CAESAR, Okean Solutions sees unique opportunities to increase visibility and the number of users of the MONSID toolset as well as to provide more functionality for CAESAR.
Benefits: A MONSID adapter for CAESAR can support FM development in current and future programs, providing rapid model development, improving HW/SW trade accuracy and efficiency for fault containment, and FM performance analyses. It is applicable to a broad range of NASA missions that leverage model-based systems engineering tools. Such missions include Europa Clipper, Mars Sample Retrieval Lander, Psyche, CubeSats (INSPIRE, SunRISE),and future missions from near-Earth to interplanetary, risk-averse, and experimental. MONSID and CAESAR are both model-based and application agnostic. The combination of these tools makes it applicable to a wide variety of DoD, ESA, JAXA and commercial programs. This innovation can be adapted to other modeling environments to streamline and accelerate FM design and development practices. Industries including aerospace, automotive, and chemical can all benefit from this technology.
