Event tree analysis - Wikipedia

The event tree analysis can be used in risk assessments by determining the probability that is used to determine risk when multiply by the hazard of events. Event Tree Analysis makes it easy to see what pathway creating the biggest probability of failure for a specific system. It is common to find … See more Event tree analysis (ETA) is a forward, top-down, logical modeling technique for both success and failure that explores responses through a single initiating event and lays a path for assessing probabilities of the outcomes … See more The name "Event Tree" was first introduced during the WASH-1400 nuclear power plant safety study (circa 1974), where the WASH-1400 team needed an alternate method to See more The overall goal of event tree analysis is to determine the probability of possible negative outcomes that can cause harm and result from the chosen initiating event. It is necessary to … See more • Enables the assessment of multiple, co-existing faults and failures • Functions simultaneously in cases of failure and success See more Performing a probabilistic risk assessment starts with a set of initiating events that change the state or configuration of the system.
