Model Based Systems Engineering for Distributed Development

Description:

As NASA looks to develop a cis-lunar infrastructure, starting with components like the Gateway, there will be considerable interest in partnerships with a wide variety of communities. Building from the success of the international partnerships for ISS, space agencies from multiple governments are looking for roles on the Gateway. The rapidly growing commercial space industry is also likely to seek roles in supporting this infrastructure. All of these potential partners will have their own design capabilities, their own development processes, and internal constituencies to support. Enabling disparate systems built in different locations by different owners to all work cohesively together will require a significant upgrade to NASA’s core systems engineering toolset. 

 

Model Based Systems Engineering holds considerable promise for facilitating this type of distributed development process, but we need to significantly improve and expand the engineering support infrastructure to enable the systems we will need for lunar exploration. Methodologies that support integration amongst tools and exchange of information between multidisciplinary artifacts are important development opportunities. The definition of interface standards and tools that enable inspection of distributed models across domains are very important. Tools or systems that allow models to be shared across development environments and trace the resulting systems back to contributions from multiple partners are also of high interest. SysML related tools are relevant to this subtopic, but need to address distributed development, multi-disciplinary system development, and the engineering of interfaces between subsystems built by different communities from requirements through testing, verification, and validation.

 

Model Based Systems Engineering for distributed development is relevant to all Human Exploration Operations Mission Directorate (HEOMD) missions, and of timely interest for Gateway development. Over the next 3 to 5 years, there will be considerable opportunity for small business contributions to be matured and integrated into the engineering support infrastructure as Gateway evolves from concept to development program.

 

During Phase I, research should be conducted to demonstrate methodologies and tools that support distributed multi-disciplinary development efforts, their technical feasibility, and NASA relevance. 


Phase I proposals should clearly indicate how the research will go beyond state of the art engineering practices. Prototypes are strongly encouraged and could take several forms such as augmentations/plugins to existing SySML tools. Phase II deliverables should include at a minimum demonstration of a prototype tool or methodology on a small system(s) that is representative or analog of a portion of lunar infrastructure, and documentation with source for NASA to explore use of the tool. The expected TRL for this project is 5 to 7.
