Researchers at the CRC investigate novel methods for developing CPS with views, a central mechanism employed to cope with the ever-increasing complexity of these systems. We pursue the goal of creating concepts for tool-supported, model-based development processes, enabling engineers from different disciplines and design spaces with different views on CPS to work together seamlessly. Dependencies between views, versions, variants, and product generations are explicitly modelled in a so-called “virtualized single underlying model” (V-SUM). The use and further development of the V-SUM will form the shared technological core of the CRC. The V-SUM approach allows engineers to develop CPS in different views and different design spaces as independently as possible, and provides assistance in managing view consistency with as much automation as possible and user interaction only where appropriate.
