Re-using SysML System Architectures

Abstract

In the development of complex systems, Model-based Systems Engineering (MBSE) has been introduced successfully into many projects. The OMG SysML as architectural modeling language is part of that success, because it offers the right perspectives to design complex systems. However, even when using MBSE methods and the SysML, the risk of re-inventing the wheel has to be overcome as well. This implies that System Engineers have to know in advance, what is already available as re-usable system asset and fits to the needs of the on-going project.

After introducing a suitable standard with OMG RAS, this paper will show different use cases for component-based design expressed in SysML using asset definition and propagation. This includes top-down exchange of system component specifications as well as bottom-up construction of new systems based on existing components. Asset reuse is based on communication. We will present the necessary communication means for propagating SysML-based system assets, which allows efficient collaboration in teams designing complex systems.
