Towards reuse in safety risk analysis based on product line requirements

Risk analysis and requirements engineering for safety-critical systems are expensive and challenging, especially for the very high reliability required, e.g., in the automotive and railway industries. Currently, risk analysis is performed by safety engineers with little or no explicit reuse. Of course, these engineers build on their previous experience in this course, but explicit reuse of related artefacts, e.g., from a dedicated repository is not available according to our best knowledge.
