The innovation proposed here is the Composable Mission Framework (CMF) a model-based software framework that shall enable seamless continuity of mission design and simulation from early stage advanced studies to detailed mission design and development. The uniqueness of our approach lies in using an open standard for systems modeling and design (SysML) to wrap mission models including the mission development process thus providing a coherent map of mission knowledge. InterCAX's Composable Object technology provides the backend wrapping, model management, and simulation orchestration capabilities to the visual SysML-based mission model at the front end. The Composable Object technology has already demonstrated the ability to power SysML-based models with math simulation capabilities for early design stages. ParaMagic is a commercially available tool being used by early adopters of SysML at JPL. The Composable Object technology has also demonstrated the ability to associate detailed design and simulation models such as those created in CAD and FEA tools. However, a big gap exists in the SysML-based world for conceptual system design and the detailed system design-based world. If the detailed system design and simulation models could be wrapped as SysML objects and the simulations and workflows orchestrated by the Composable Object technology, it will cover the entire gamut of complex system modeling and analysis world from trade studies and optimization to project scheduling. The key objective of Phase 1 is to wrap both conceptual and detailed system design and simulation models as SysML objects which has not been done before, and to demonstrate continuity of mission concepts from simple to detailed implementation.
