Probabilistic risk assessment - Wikipedia

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 and overall system analysis. This analysis technique is used to analyze the effects of functioning or … 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 fault tree analysis due to the fault trees … See more Performing a probabilistic risk assessment starts with a set of initiating events that change the state or configuration of the system. An initiating event is an event that starts a reaction, … See more 1 = (probability of success) + (probability of failure) The probability of success can be derived from the probability of failure. Overall path probability = (probability of event 1) × (probability of event 2) × ... × (probability of event n) See more • Enables the assessment of multiple, co-existing faults and failures • Functions simultaneously in cases of failure and success 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 use detailed information about a system to understand intermediate events, accident … See more 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.
