Leveraging a Traceability Information Model in order to enhance the maintenance of automotive Safety Assurance Cases

Detta är en Master-uppsats från Göteborgs universitet/Institutionen för data- och informationsteknik

Sammanfattning: In safety critical systems, Safety Assurance Cases are created in order to provideargumentation as to why a system is reasonably safe. In the automotive industry,the ISO 26262 standard is complied with in order to provide comprehensiveand structured argumentation for developed electrical and/or electronic (E/E) systemsin regards to function safety. Previous research, while seeing initial resultsin improving traceability in Safety Assurance Cases, has expressed the importanceof creating trace-link between the safety related artefacts and elements in order toprovide the argumentation of as to why the complex real-world systems are safe.By utilising the Design Science Research methodology a Traceability InformationModel emerged as the design artefact, which has been validated in an industrial setting.The aim is to contribute in how traceability of Safety Assurance Cases can berepresented and what the appropriate relationships are. In this paper, the artefactswhich are important to traceability and the relevant relationships among them inSafety Assurance Cases are presented and discussed. The results of this study couldhelp future research in identifying the important trace-links required to facilitatethe maintenance, by introducing traceability, in other industrial cases and providesa starting point for work in automation of the creation of Safety Assurance Cases.
