Integration of domain-specific simulation models into descriptive system models by using SysML

Several observations at industry examples have shown that there is a need to close an existing gap between system architect's model and domain experts' models. Therefore, a minimalistic approach is presented, which allows integrating executable domain models into a system model using a state of the art Model Based Systems Engineering (MBSE) authoring tool. Such MBSE approaches and tools offer possibilities to model requirements and interdependencies with respect to the system's structure, functions and behaviors. Domain architects use simulation models to study the system behavior and to verify specific system requirements. System architects can re-use such simulation models to keep track of the system validity in case of design changes.
