Component Story Diagrams: A Transformation Language for Component Structures in Mechatronic Systems∗

To cope with the high complexity of software in ad-vanced technical systems, the software of these sys-tems is often built in a component-based fashion. The growing usage of self-adaptive techniques leads to so-phisticated reconfigurations of the software compo-nent structures during runtime. Current modeling ap-proaches for component-based software systems do not include a transformation language for the speci-fication of component structure reconfigurations. In this paper we therefore introduce an extension of a component-based modeling approach. This extension enables (1) the specification of hierarchical compo-nent structures and (2) the specification of structural transformations based on the specified hierarchical component structures. Further, as we consider mecha-tronic systems, we also show the predictable runtime behavior of the transformations. 1
