FTA – Connect fault trees

Question

Status : implemented  Priority : Major, #7     Schedule : (according to Project Owner)      Current state :working if you use transfer gates     Critisism on current state : none     Objective of the change : efficient workflow     Proposed change : none  Original Author : Peter Ploß     is it possible to couple two or more FTA models? e.g. you have a "base event #FMEDA Current wrong" in the System FTA and that should represent the top event of a Hardware FTA; if everything has to be modelled inside one model, how is it possible to create some kind of hierarchy? (no packages are available, like for system models)     Anser from ANSYS   20191115_EMB: set to working. Transfer Gate usage is decided.we need to evaluate if this approach can be used for component fault trees (CFT)     2019-07-23_Ploß: could you please clarify  during the meeting how the Transfer Gate Solution would differ from "MOE" (multiple occurring events)?     2019-12-11 ansys: MOE is a single event that is used multiple times in the tree and consequently contributes multiple times; a transfer gate relates to a subtree that can be reused multiple times  Hierarchy can be obtained using "child diagrams"; view "outline" gives a list of events (by type) for the current FTA model -> issue completed        a parent node: FTA, line 45"
