Coursebook HOD-Fix: Importance Measures for Fault Trees
Written on 09.02.2024 14:41 by Andreas Schmidt
Dear students,
Surprisingly, there were notation errors in the importance measures in Quantitative Fault Tree Analysis that nobody has spotted in the last two years. This issue was raised on the forum.
Note that all of you who passed safe-v have provided a working solution and demonstrated an understanding. Furthermore, all the provided results were correct, apparently thanks to multiple errors cancelling each other out (which also led to this bug hiding for so long). We believe something about errors in the real world can be learned from this story.
We just updated the respective course book section. It might be valuable for you to have another look at the corrected (and clarified) version.
We also realized that QFTA sample solutions are missing (which apparently none of you missed?). We plan to release them later today. If you urgently need them, ... well, use your safe-v implementation to double-check the results you produce by hand.
With that, keep up the good exam preparation work and see you on Tuesday!
Best Regards,
The HOD Team
