Visual fault tree analysis with AND/OR/Voting gates, exact probability calculation, minimal cut sets, and importance ranking. Connected to your DFMEA failure modes and field data from Resolve.
Why Fault Tree Architect
❌ Traditional Approach
Component FMEA captures individual risks but misses how failures combine at system level.
✓ With Fault Tree Architect
Top-down system analysis shows exactly how component failures propagate to system failure.
❌ Traditional Approach
1-10 FMEA scales don't tell you actual probability of system failure.
✓ With Fault Tree Architect
Quantitative probability calculation from gate logic and base event failure rates.
❌ Traditional Approach
Fault trees built in separate tools with no link to FMEA or field failure data.
✓ With Fault Tree Architect
Pull failure modes from DFMEA. Use field data from Resolve as base event probabilities.
Complete FTA Platform
System fails only when ALL inputs fail. Model redundancy and backup systems.
System fails when ANY input fails. Model series configurations and single points of failure.
System fails when K or more of N inputs fail. Model partial redundancy and majority voting systems.
Exact top event probability from gate logic and base event failure rates. Support for rare-event approximation.
Automatically identify all minimal combinations of basic events that cause system failure. Critical path analysis.
Fussell-Vesely, Birnbaum, and Risk Achievement Worth. Rank components by contribution to system unreliability.
Interactive tree construction — no scripting required. Zoom, pan, and navigate large fault trees with smooth interaction.
Import FMEA failure modes as basic events. Use occurrence ratings or field data as base event probabilities. Bi-directional linking.
Reference external sub-trees for modular, reusable analysis. Build complex system models from reusable subsystem trees.
AI suggests gate structures and basic events based on system description. Automatically identifies common failure patterns.
