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 disciplines 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 example by introducing model hierarchies, by ontological foundations, by developing universal modeling languages such as UML, or by specifying domain-specific modeling methods (DSMMs) 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 ecosystems. We approach this in the lecture from a rigorously 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. We will illustrate the paradigm of model-centric architecture with the results of projects we have carried out in the areas of assistive systems, mechatronic systems and Quality Aware Software Engineering.
