For example, event tree analysis is a major component of nuclear reactor safety engineering.
[2] Event tree analysis is a logical evaluative process which works by tracing forward in time or forwards through a causal chain to model risk.
[3] An event tree is an inductive investigatory process.
[5] An event tree may start from a specific initiator such as loss of critical supply,[6] or component failure.
Software has been created for fault tree analysis and event tree analysis and is licensed for use at the world's nuclear power plants for Probabilistic Safety Assessment.
