The Power of Model-Centering
Models are the basic human tools for managing complexity and understanding. As such, they play a key role in all scientific and engineering disci-plines as well as in everyday life. Many modeling paradigms have evolved over time in different disciplines, resulting in a wide variety of modeling languages, methods and tools that have come and gone. This is particularly true for informatics, which is a modeling discipline in itself: for long it has systematized the field of modeling, for exam-ple by introducing model hierarchies, by ontologi-cal foundations, by developing universal modeling languages such as UML, or by specifying domain-specific modeling methods (DSSMs) for areas of application where universal approaches fail.
In the context of digital transformation, modeling plays a central role in ensuring the functionality, security and quality of complex digital ecosys-tems. We approach this in the lecture from a rigor-ously model-centered perspective, which sees a digital ecosystem as a construct of networked model handlers in the sense of model producers and model consumers, whereby these handlers in turn are instances of models. For modeling, do-main-specific methods tailored to the respective task are used. Consequently, the components of model-centered digital ecosystems each also have an interface for metamodel and model manage-ment.
We will illustrate the paradigm of model-centered architecture with the results of projects we have carried out in the areas of assistive systems, mech-atronic systems and Quality Aware Software En-gineering.
