The main objective of any hazard analysis is to identify all potential hazards and system level failures caused by the system or interactions in which the system is involved, and to understand the risk of each such hazard. The hazard analysis usually includes the identification of the malfunctions, operational situations, conditions, and misuse for a considered system or equipment under consideration.
The hazard analysis is conducted differently in the various industry domains (and even inside of one domain). In medini this analysis of potential hazards and the evaluation of their risks is done in the hazard analysis editor. Each editor provides the domain specific fields and risk graph to analyze and assess the risk. The following domains are supported:
Hazard Analysis and Risk Assessment (HARA) according to ISO 26262, part 3 (cp. Hazard Analysis and Risk Assessment (Automotive))
Functional Hazard Assessment (FHA) according to ARP 4754A and ARP 4761, section 3 (cp. Functional Hazard Assessment (Aerospace))
Further risk graphs are available as generic profiles and templates. Please contact the Ansys medini team for further information.
At its core, the editor supports the analysis of functions and malfunctions in various operational situations. Each such entry can be assessed in terms of the risk and associated to the safety goals and objectives derived thereof.
