ISO 26262框架下的安全分析

内部培训

Inductive and deductive safety analyses play an essential role within the ISO 26262 safety life cycle. Qualitative analysis methods are used to identify failures whereas quantitative methods are utilized to predict the frequency of failures.

This one-day training class introduces the fundamentals of common safety analysis methods such as FMEA, FMEDA, and FTA and discusses the role of these methods in the development of safety-related E/E systems as per ISO 26262.
