Abstract

Techniques of safety assurance using fault trees for identifying dormant system failure states are provided. Both operational failure events, as well as diagnostic failure events are included in a fault tree and the operational failure events are then correlated with the diagnostic failure events, which enables an identification of the dormant system failure states. A component fault tree can be used.
