1. A method for fault tree analysis (FTA) of a system, the method comprises:
preforming FTA of the system using multiple hybrid events related to multiple units of the system to provide a FTA result, wherein each hybrid event represents both latent failure modes and evident failure modes related to one of the multiple units of the system and is associated with a single failure rate and a single failure probability of a single unit; and responding to the FTA result.
