Fault Tree Analysis - UK Essays.
Fault Tree Analysis is a top down approach to problem solving. What this means is that you are taking a top level view of a process or a product, identifying a potential failure or undesired event which could arise and trying to understand the potential causes of the failure event.Fault tree analysis maps the relationship between faults, subsystems, and redundant safety design elements by creating a logic diagram of the overall system. The undesired outcome is taken as the root ('top event') of a tree of logic. For instance the undesired outcome of a metal stamping press operation is a human appendage being stamped.Fault tree analysis is in the form of a top-down tree, while FMEA usually has a matrix structure with all the key measurements (severity rating, occurrence rating, process controls, detection rating and risk priority number etc.) right on the top column.
A fault tree diagram is used to conduct fault tree analysis (or FTA). Fault tree analysis helps determine the cause of failure or test the reliability of a system by stepping through a series of events logically. Benefits of Fault Trees.Fault tree analysis (FTA) is used to assess the frequency of an incident. A fault tree is a diagram that shows how primary causes produce events, which can contribute to a particular hazard. There are several pathways in which a single primary cause can combine with other primary causes or events.

For risk management and assessment a good understanding of Fault Tree Analysis (FTA) can be an asset. Fault tree analysis is also a tool for discovering product failure, engineering failure, ranking the effects of item failures and human.
