Research focus

My research focus is on the automation of safety analyses with a focus on the widely used fault tree analysis (FTA). To accelerate this and effectively enable rapid prototyping in the design of safety-critical systems, a concept for the automated composition of component-level models is to be developed. The elaborated approach builds on previous work of the chair, in particular on component fault trees (CFTs).

We propose annotating CFT models with a type system to enable their automated composition. The type annotations thereby extend the textual descriptions in the models with semantic information that can be processed by machine. In this way, the manual process of connecting interface elements in the models is to be partially automated.
