Find out how to figure out system safety issues by using various prescribed methods for the purpose.
This course will give you an overview and a classification of methods used to assess the safety of a system. Most common safety analysis methods are laid out and their workflows are described in detail. The course has a high practical dimension, with numerous examples including group work for course participants, which will conduct each method over a practical technical system of choice. The practical exercises would focus on the automotive domain, with analysis tackling specifics of hardware and software components in a system safety decomposition.
Course topics:
- Introduction to safety analysis methods, system model analysis
- Preliminary Hazard List (PHL), Preliminary Hazard Analysis (PHA), Failure Mode and Effect Analysis variants (FMEA/FMEDA/FMECA/Fu-FMEA), Functional Failure Analysis (FFA), Hazard and Operability Analysis (HAZOP), Fault Tree Analysis (FTA), Event Tree Analysis (ETA), Dependent Failure Analysis (DFA)
- New analysis in the context of ISO 21448 SOTIF, such as System-Theoretic Process Analysis (STPA)
- Key quantification (such as Safe Failure Fraction and Diagnostic Coverage)
- Hazard identifications, minimal cut sets, assessment of dependent failures and potential weaknesses
- Identification and analysis of common cause failures, Identification, and analysis of cascading failure, Assessment of their risk of violating a safety goal
- Mitigation: definition of safety measures
