This article describes our current work on the combination of an ontology-based knowledge representation and formal analysis procedures. We use formalized system engineering knowledge and partial architectural information (induced by a set of requirements) to formalize natural language requirements and to identify inconsistencies based on this formalization. Our analysis combines requirements specified by patterns and an ontology-based product breakdown structure. As an example, we identify inconsistencies between Mean Time Between Failure (MTBF) specifications of systems and their subsystems.
