Model-Based Safety-Cases for Software-Intensive Systems
This is an incremental position paper that outlines research issues for improving safety certification in software-intensive systems, primarily relevant to safety engineers and certification bodies.
The paper addresses the challenge of software certification by proposing an ideal model-based safety case framework that incorporates defect hypotheses and failure characterizations, but it does not provide concrete results or numbers as it is a position paper.
Safety cases become increasingly important for software certification. Models play a crucial role in building and combining information for the safety case. This position paper sketches an ideal model-based safety case with defect hypotheses and failure characterisations. From this, open research issues are derived.
