Because of the possibly large variability in families of software systems and the complex dependencies between individual software components, product derivation in the context of software-intensive systems is not a trivial task. In this demonstration, we show the domain-independent structure-based configuration tool KONWERK, extended with a knowledge base containing a configuration model representing the domain of car periphery supervision systems. Using this tool, reasoning methods known from structure-based configuration are applied in the area of software-intensive systems. Starting with i) a model describing the variability of already realized software components and ii) a concrete task specification for a specific product, during a knowledge-based product derivation process a description of the needed software components is derived. This description is to be used for realizing, i.e. compiling and linking the desired product. The applicability and usefulness of such an approach will be shown in the demonstration.
