Fault Tree Analysis

Show Index


Fault Tree Analysis (FTA) is one method for estimating safety and reliability of products and facilities. As for problems that might occur (such as faults and accidents), it is possible to analyze the conditions under which those problems occur, identify their cause, and estimate the occurrence probability of such problems. Although originally developed as a method for estimating the reliability of missile-launch-control systems, FTA is now used for evaluating the safety of plant and equipment.
