Fault Tree Analysis
A top-down deductive failure analysis method that starts from an undesired top-level event and decomposes it layer by layer into intermediate and basic events that may cause it, describing causal relationships with logic gates. It is widely applied in safety-critical fields such as aerospace and the nuclear industry.
Timeline (last 90 days)
Fault Tree Analysis (FTA) is a top-down deductive failure analysis method that originated in the aerospace and nuclear industries in the 1960s; it starts from a top-level undesired event and decomposes it layer by layer into intermediate events and basic events, using logic gates to describe causal relationships.
For AI systems, FTA can help teams discover engineering failure chains that are neither purely security vulnerabilities nor abstract alignment problems, for example data pipeline delays causing feature distribution shift, which then triggers abnormal model outputs, ultimately amplified in downstream applications.
