My main focus of research is on the automation of safety analyses with a focus on the widespread Fault Tree Analysis (FTA). In order to accelerate the analysis process, a concept for the automated composition of models at component level is developed. The approach is based on previous work of the chair, in particular on Component Fault Trees (CFTs) and Component-Integrated Fault Trees (C2FTs).

CFT models are annotated with a type system for automated composition. The type annotations extend textual descriptions in the models with semantic information that can be processed using tools. This helps in automating the otherwise manual process of connecting interfacing elements in the models and accelerating the analysis process.

The approach is also viable for automating the exploration of the system design space regarding functional safety. Variable parts of the architecture for which multiple development alternatives exist are modeled with variants instead of concrete components. Variants define the functional interface in the architectural model and contain CFTs for every possible implementation. Several architecture models can thus be derived from the functional system model, for which CFTs are automatically generated and analyzed. Fault Tree Analysis thus becomes a benchmark for different system architectures.
