Review:
Event Tree Analysis
overall review score: 4.4
⭐⭐⭐⭐⭐
score is between 0 and 5
Event Tree Analysis (ETA) is a systematic, graphical method used in risk assessment and reliability engineering to evaluate the potential sequences of events following an initiating event. It visually maps all possible outcomes and paths, helping analysts identify potential failures, assess their likelihoods, and develop mitigation strategies. ETA is widely utilized in industries such as aerospace, nuclear power, chemical processing, and safety engineering to improve system safety and resilience.
