A Library of Reusable NASA SysML Models

The proposed innovation is to demonstrate the feasibility of building a NASA-wide SysML Reusable Library Architecture and Management Tool. The need for a library of re-usable model elements is critical in order to support future space missions by making model development cost effective. NASA centers are using Model Based System Engineering (MBSE) and creating Systems Modeling Language (SysML) representations of their systems. The proposed NASA-wide reusable SysML library effort will investigate the feasibility of consolidating these multiple models to better understand and prepare for model reuse across the agency. An effective SysML reusable library is one that provides the user with the ability to locate model elements relevant to their needs. There needs to be a library architecture with a taxonomy that supports the multiple NASA space system models. There needs to be a library management tool to allow storing, searching, and accessing the SysML model taxonomy that returns models or model elements that pertain to the user’s modeling needs. The proposal will deliver a blueprint of a taxonomy that will support the different types of model elements and additional facets, building off our initial efforts with preliminary library architecture and facet identification. The envisioned library will expand the taxonomy to include additional classification for space systems, e.g., satellites and autonomous systems.

NASA's Gateway and Artemis program as well as its ambitious program of innovative planets robotics missions will rely on effective MBSE effort. The Phase I proposed concept will be developed to support new manned space vehicles and planetary surface habitats that NASA plans to develop, as well as Lunar habitat and advanced ISU structures and robotics systems. In the short term, the system can be used for NASA projects such as CubeSat missions, Gateway Lunar Rover, advanced life support systems, and Crew Health and Performance system.

The Department of Defense (DoD) have large complex systems that use the MBSE approach and can therefore benefit from a library of reusable SysML models. Our system can significantly reduce the costs related to developing new complex systems in DoD funded projects. Our concept can be also used in a broad range of commercial areas, such as automotive, airline and power plant systems.

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
