Dr. Carlos E. Budde

In this lecture we'll cover Fault Tree Analysis: an industry-strength technique to assess and mitigate risks.

Introduced by Bell labs in the 60's for ballistic missiles, and popularised by NASA in the 00's for the aerospace industry, FTA is pervasive and applied to diverse fields such as data centres, power plants, airplanes and transport in general, web apps for banking, etc.

Topics covered in this lecture include:

Fault Trees:
- Static FTs
- Repairable FTs
- Dynamic FTs
Qualitative analyses:
- Minimal cut-sets
- Cut sequences
- Common cause failures
Quantitative analyses:
- System reliability
- System availability
- Meant Time To Failure
Computation methods
- Exact algorithms (and their limitations)
- Correct interval algorithms
- Statistical approximation algorithms
