Multi-View Modeling to Support Embedded Systems Engineering in SysML

Embedded systems engineering problems often involve many domains, each with their own experts and tools. To help these experts with analysis and decision making in their domain, it is desirable to present them with a view of the system that is tailored to their particular task. In this paper, a model integration framework is demonstrated to address issues associated with multi-view modeling. The Systems Modeling Language (OMG SysMLTM) is used as a general language to represent a common model for the system as well as the dependencies between the different domain-specific tools and languages. To maintain consistency between these domain-specific views, model transformations are defined that map the interdependent constructs to and from a common SysML model. The approach is illustrated bymeans of amechatronic design problem involving views in multiple domain-specific tools, namely EPLAN FluidTM (to create production ready layouts) and Modelica R (for dynamic system analysis).
