Hi Alan,

Thank you for your comment. I am sorry to reply late since I did not realize your comment. (There is no notification when someone drops a comment to my post.)
I am glad to hear that this add-in works fine.

Hi Takeshi,
I just tried to use your add-in again -- I installed it on v15, and it's now obvious how to use the plug-in. For some reason, when i installed it previously it was not showing up in my EA, or i was not being smart in finding it. Thank you for this plug-in, I think it could be very useful.

Hi Takeshi,

thank you for providing the add-in for Fault Tree Analysis. In case someone is interested in a more sophisticated Fault Tree Modeling and Analysis solution (including automation support) in EA, you may also find our safety engineering tools for EA "safeTbox" interesting. It is free and offers many features that you can review at https://www.safetbox.de/. For instance, safety-oriented architecture modeling, hazard and risk analysis, safety analysis with (Component) Fault Trees and safety argumentation with the Goal Structuring Notation (GSN).

Best regards
Jan Reich from Fraunhofer IESE
