From UAF to SysML: Transitioning from System of Systems to Systems Architecture

The fourth industrial evolution, Internet of Things, and large-scale machine-to-machine interactions are driving digital transformation in the industry. Model-based Systems engineering (MBSE), as a new paradigm of capturing and analyzing knowledge about the system, is one of the core factors to drive this transformation. MBSE practices are more and more widely applied to system-of-systems (including enterprise and mission) engineering, which becomes a crucial part of the successful digital transformation. The core challenge today is how digital continuity can be maintained by connecting system models to system-of-systems models, especially when multiple parties are involved in their creation and exploration. This paper studies Systems Modeling Language (SysML) as the standard language to model systems, and Unified Architecture Framework (UAF) as the framework and Unified Architecture Framework Profile (UAFP) as the language to model system of systems and proposes an approach for transitioning from one to another in an integrated modeling environment.
