I have taken to using Powerpoint to generate fault trees in condensed form (please see attached figure). I basically organize the fault tree in a manner similar to Windows File Explorer. It would be nice if the nodes of the tree were collapsible like any good hierarchy navigation GUI. Is...
I am following the OpenFTA (Fault Tree Analysis) User Manual at http://www.openfta.com/Download.aspx. Page 81 uses the inclusion/exlusion expansion to express the top-most fault in terms of minimal cut sets. Page 82 shows the same inclusion/expansion expansion broken up into components...
I installed OpenFTA version 2 on Windows 7 64-bit. I can draw a fault tree, define Primary Events, and associate each basic event with a Primary Event. However, when I try to validate or create minimal cut sets, the application crashes without any error messages. The log file always says the...
I am test driving an app (OpenFTA, http://www.openfta.com) for small Fault Tree Analyses on Windows 7 64-bit. In one of the functions (defining a "Primary Event"), the radio buttons are not visible. Googling with the following search phrase does not yield anything relevant:

I am familiarizing myself with FTA and OpenFTA. If I have multiple instances of a Primary Event in my fault tree, does that mean that they are all one common event? Thanks.
I'm picking up FTA theory from "An Introduction to Reliability and Maintainability Enginenering", Charles Ebeling. In his final FTA example, he has an event consisting of the intersection of 3 events:
event = {wheel subsystem failure, b3, b4}
"Wheel subsystem failure" (wsf) is further...
