Vernetzung von MBSE-Systemarchitekturmodellen und physikalischen Verhaltensmodellen

Virtual validation with physical behavior models is nowadays an integral part of product development. However, full virtual validation is effortful due to the expense of model building for physical behavior models. Utilizing Model-Based Systems Engineering (MBSE) methods as a solution approach to support model creation by providing and organizing the system data and knowledge for model creation in a central system architecture model is currently reaching its limits. This is primarily because the detailed knowledge about physical behavior required for model building is not adequately represented in MBSE system architecture models. This work therefore develops MBSE modeling methods for physical systems that can be used to link physical behavior models with MBSE system architecture models. For the first time, the methods enable MBSE architecture modelling taking into account physical contacts and an organization of physical behaviour models at contact level. To accelerate modeling, methods are derived with which physical behavior models and MBSE system architecture models can be automatically generated from each other. It is shown that the time saved by automated generation of behavioral models outweighs the effort of MBSE architecture modeling with just two changes to the system architecture.
