INCLUDING SYSTEMATIC FAULTS INTO FAULT TREE ANALYSIS [PDF]
IFAC Proceedings Volumes, 2006 : Fault Tree Analysis (FTA) is a technique widely used for fault forecasting of physical systems. Although FTA is considered a well established safety analysis technique, paradoxically classical Fault Trees include only random faults. However, in modem automated systems, undesirable events arise not only from random hardware faults but also from ...
