Model-Based Design Assessment and FM Visualization Technologies in TEAMS

Qualtech Systems, Inc. (QSI), in collaboration with Dr. Stephen B. Johnson, President of Dependable System Technologies, LLC (DST), plan to develop techniques and the concomitant software modules for enabling modeling and visualization in QSIrsquo;s TEAMSreg; Toolset to represent the entire FM design as part of a system design. The main objective of the proposed effort is to have TEAMSreg; complete the control loop in terms of incorporating the ldquo;Responserdquo; (the lsquo;Rrdquo; in FDIR) loops as part of its design and analyses of FM Architecture. This will include improvements to address FM metrics for failure response/recovery, and will be linked to ongoing efforts to implement FM Metrics and to overall system autonomy, but targeting SMD science missions and their unique goals.The proposed effort will result in a novel capability that incorporates the ldquo;Recoveryrdquo; aspect of FDIR within TEAMSreg; and enables FM Visualization of design architectures, which then links to a clear and concise set of FM metrics to minimize mission risks to desired levels. TEAMSreg; can leverage built-in modeling features for performing FM Architecture Design Assessment, such as Fault Trees and FM Metrics related to Failure Detection and Isolation. Switches in TEAMSreg; models facilitate their use in multiple system modes. This feature will be leveraged to enable Recovery Loops across multiple scenarios.The proposed effort seeks to aid the visualization and assessment of FM design for system(s) in multiple usage scenarios by utilizing existing capabilities and introducing new capabilities to TEAMSreg; for the computation and evolution of relevant FM analyses. The added capabilities include information integration; extending the system modeling capabilities; and assessing the effect of implementing diagnostic decisions on the overall functionality of the system.
