Abstract [en]

Hazard identification is an essential but very de- manding task for the development of safety-critical systems (SCSs). Current practices suffer from one or several drawbacks listed below: 1) a common hazard conceptualization is missing and thereby ambiguities may arise and, 2) there is still a need to formalize the experience of analysts and lessons learned from previous system development in a structured way to facilitate future reuse. and, 3) some hazard identification techniques require well-known system behaviors represented by models, such as automata and sequence diagrams, to identify hazards, and however such models are typically susceptible to changes or even not available in early stages. In this paper, we propose an ontological approach to support hazard identification in the early stages of the development of SCSs. The approach aims to improve hazard identification results in terms of completeness and unambiguity. A robotic strolling assistant system is used to evaluate the proposed approach.
