Linking Fault Tree and Event Tree

Event Tree Analysis (ETA) complementing your Fault Tree Analysis (FTA) is like putting salt on your popcorn. Event tree diagrams provide an excellent way of showing the possible outcomes of a hazardous event (often modelled in a FTA study). An ETA diagram is a simple, logical and easy to read diagram that breaks down data to show the possible consequences of failures in an FTA study.Event trees provide an inductive approach to reliability and risk assessment and are constructed using forward logic.

FaultTree+ in Reliability Workbench includes integrated event tree analysis. The event tree model may be linked to the fault tree model by using fault tree gate results as the source of event tree probabilities. FYI, if you already have a copy of FaultTree+ the Event Tree Software is included!
