Risk Assessment
Fault Tree Analysis
Trace combinations of events that can produce a defined system failure.
Purpose & Benefit
When This Activity Helps
Use when a critical failure outcome needs structured examination, particularly where interacting faults or common causes matter. It helps target prevention and verification at the system level.
Project Information
Typical Inputs
The scope is tailored to the available evidence. Useful inputs include:
- Defined top event and system boundaries
- Functional architecture and fault behaviour
- Failure data and dependency assumptions
Engineering Approach
How SPACEREL Supports Your Project
SPACEREL builds a logical model from the top event to contributing conditions. Qualitative analysis identifies critical combinations; quantification is included only where the data and dependency treatment support it.
Documented Outcomes
Typical Deliverables
Deliverables are agreed before work starts and can include:
- Fault tree and analysis assumptions
- Critical event combinations and contributors
- Mitigation and verification recommendations
