NASA uses a variety of tools to conduct its FM activities. However, these tools are varied and disjoint, and require manual intervention to transfer data from the output of one tool to the input of another. This process is tedious, error-prone and scales poorly for large, complex systems. In addition, these tools are often “silo’ed” to the singular functionality for which they were designed. This prevents FM engineers from gaining insight into the overall system level design and characteristics that are the key to transparency, verifiability and efficiency of implementing and testing FM. FM support tools need to have powerful fault modeling and analytic capabilities to capture their operational procedures and mission complexity.
Qualtech Systems, Inc. (QSI), in collaboration with Dr. Stephen B. Johnson, President of Dependable System Technologies, LLC (DST), plans to develop techniques and the concomitant software tools to “integrate multi-domain data” and “perform FM architecture trades” by leveraging QSI’s TEAMS® (Testability Engineering and Maintenance System) toolset. The solution will provide the capability to cost-effectively create a model, and utilize that model to perform FM architecture studies, both visually/qualitatively, and quantitatively. This ability coupled with the option of using the same model for Operations, will greatly benefit science missions. The main focus of this effort will be to (1) capture diverse and disjoint data products and multi-domain modeling information into TEAMS® for standardizing FM Techniques and Processes and improve the productivity of model (knowledge) creation and FM design process, (2) conduct Architecture Trade Studies focusing on FM (including sensor allocation) effectiveness, (3) introduce ancillary capabilities in TEAMS® to support the main tasks such as Common Cause Failures (CCFs), Probability of Failure on Demand Failure (PFD), and, .(4) develop an FMEA (Failure Mode and Effect Analysis) exchange tool.
The proposed technology will allow NASA to better plan and execute future Science Missions. It can also operate as part of NASA’s next generation Mission Control Technology, allowing NASA to utilize the FM and mission satisfiability information for improved mission execution while improving safety and mission success probability. Europa is strong candidate for demonstrating the multi-domain knowledge import including SysML. NASA’s proposed Gateway spacecraft has some simulation and vehicle models which can be used as FM information sources.
