As NASA and the space community, in general, strive to push the boundaries of space travel with planned deep-space missions, increased system autonomy and resiliency have inevitably become key technology needs. Designing these complex systems requires a multi-disciplinary approach that connects fault management (FM) with model-based systems engineering (MBSE) to ensure that resilient, fault-tolerant systems are architected and modeled during the design phase. NASA has been using TEAMS^® as their fault management tool of choice for several decades. NASA also uses Systems Modeling Language (SysML) for systems engineering, including the design, specification, verification, and validation of systems.

SysML v2 is the upcoming revision of the SysML, and QSI is working with SysML v2 Submission Team (SST), a diverse group of end users, vendors, academics, and government liaisons involved in the development of SysML v2 specifications, to extend the SysML v2 for Fault Management and Diagnostics. In a SBIR project funded by NASA, QSI demonstrated translation capabilities from a SysML v2 model to a TEAMS^® model, which will enable Systems Engineers to analyze the fault management aspects of a system design captured in SysML v2  using QSI’s Model based reasoning COTS product, TEAMS^®-Designer. Using TEAMS®-Designer, analysts may perform Fault Modes, Effects, and Criticality Analysis (FMECA) and Fault Tree Analysis to analyze, quantify and improve the diagnostics and availability of the system. The improvements resulting from such analysis can be brought back into SysML in industry standard formats such as the Risk Analysis and Assessment Modeling Language (RAAML), facilitating broader stakeholder visibility.

Recently, the DoD SysML v2 Transition Project hosted a 1-day SysML v2 Transition Information Session at the INCOSE 2024 IW in Torrance, California. The project, led by the DoD Digital Engineering, Modeling, and Simulation Office, provides guidance to assist organizations in their transition to SysML v2. QSI’s multidisciplinary approach to integrate Fault Management analysis with Systems Engineering was presented in INCOSE 24.

Qualtech Systems (QSI) has been awarded a multi-year contract to develop and implement autonomous monitoring, fault-prevention and health management systems for spacecraft like the proposed Lunar Gateway and possibly other vehicles and habitats.

QSI was one of four businesses, and the only software provider, selected for this prestigious award. “Each business has a track record of success with NASA, and we believe their technologies will have a direct impact on the Artemis program,” said NASA’s Jim Reuter in a news release.

QSI is proud to be part of NASA’s Artemis program. “With the Artemis program, NASA will land the first woman and next man on the Moon by 2024, using innovative technologies to explore more of the lunar surface than ever before. We will collaborate with our commercial and international partners and establish sustainable exploration by the end of the decade. Then, we will use what we learn on and around the Moon to take the next giant leap – sending astronauts to Mars.”

While we reach for the moon, let us also help you improve your diagnostics and Field Service here on Earth. Please look at our 2020 promo and contact us to start your own mission of excellence!

Folks, if you are attending Field Service Medical 2014, let’s get together and help you carve out your M2M Strategy. Simply put — don’t create a “needle in a haystack” problem by spending all those big bucks collecting tons of data in the hope that it may be useful to somebody somewhere? Who is going to ever analyze it? Don’t collect a haystack – collect only the needles, and deliver smarter service! Check out our M2M demo for more information!
