ENGR 100 Lecture Notes - Lecture 25: Event Tree, Hazard Analysis
Document Summary
An event tree analysis (eta) is a deductive procedure that shows all possible. By studying all relevant accidental events (that have been identified by a preliminary. Design and procedural weaknesses can be identified and probabilities of the various. Given an undesired event (e. g. fault), what"s the probability that system responds. System design is such that response to initializing event is a logical sequence of. Suited to analysis of failsafe mechanisms in safety critical systems. Initiating events can be internal or external. Consequences of the event traced though the system to the ultimate conclusion. Analysis is boolean (components either succeed or fail, there is no partial. Judgment required in choosing which system events to consider for eta. components that are engaged in response to the event. successfully (safely) (success or failure) success) Identify (and define) a relevant accidental (initial) event that may give rise to. Identify the barriers that are designed to deal with the accidental event.
