Learning objectives
- Explain the core concepts behind fault tree and event tree analysis
- Construct fault tree diagrams to highlight potential failure paths
- Apply methods to identify key failure paths (e.g., minimal cut sets, common cause failure)
- Perform quantitative analysis to calculate top event probabilities and identify critical contributors
- Understand data requirements and how to use failure rates, probabilities, and reliability data
- Recognise the limitations, assumptions, and uncertainties in FTA models
- Build event tree analyses that capture various outcome scenarios
- Apply both methods to guide safer, more reliable system designs
- Understand the software options for FTA and ETA
- Integrate with other risk tools, such as Layer of Protection Analysis (LOPA), and Quantitative Risk Assessment (QRA)
Key contents
- Basics of fault tree analysis (FTA)
- Building and interpreting fault tree diagrams
- Qualitative FTA (minimal cut sets, common cause failure, importance measures)
- Quantitative FTA (failure rates, test intervals, reliability distributions)
- Data sources and reliability data
- Fundamentals of event tree analysis (ETA)
- Creating event tree diagrams for different initiating events
- Combining FTA and ETA for a holistic approach to risk assessment
- Using FTA and ETA in process safety and risk management
- Software options for FTA and ETA
- Limitations, assumptions, and uncertainties in FTA and ETA models
Prerequisites
Basic knowledge of risk assessment or safety management concepts is recommended. No prior experience with FTA or ETA methods is required.
