Learning objectives
- Explain the core principles and applications of fault tree analysis (FTA) and event tree analysis (ETA)
- Construct fault tree diagrams to identify failure paths and system vulnerabilities
- Apply qualitative techniques such as minimal cut sets, common cause failure analysis, and importance measures
- Perform quantitative FTA to calculate top event probabilities, system failure frequencies, and critical contributors
- Identify and gather required data, including failure rates, probabilities, reliability distributions, and test intervals
- Recognise the assumptions, limitations, and uncertainties inherent in FTA and ETA models
- Build event tree diagrams to model various outcome scenarios following initiating events
- Use FTA and ETA results to inform safer, more reliable system and process designs
- Understand available software tools for conducting FTA and ETA
- Integrate FTA and ETA with other risk analysis tools, such as Layer of Protection Analysis (LOPA) and Quantitative Risk Assessment (QRA)
- Apply FTA and ETA techniques in real-world case studies and practical exercises
- Understand and apply uncertainty analysis and sensitivity studies to strengthen risk insights
