Reliability: Methodologies, Standards, and Tools

Hello dear DS readers,

Today I had a presentation at Fraunhofer about the most widely used reliability methodologies like RBD, FTA, FMEA etc. Here are the slides from this presentation that give general descriptions of the classical reliability methods, industrial standards, and software tools.

Also, there is no post about these methodologies in my blog. So, in order to cover this gap, I've recorded six short video podcasts using these slides. I hope they are not too boring and maybe helpful.

Part 1: This is the first part, the introduction,  of a presentation about reliability methodologies, standards, and tools.

Part 2: This part of the presentation describes practical reliability metrics: MTTF, MTBF, MTTR, and failure rate.

Part 3: This part of the presentation tells about reliability block diagrams, fault trees, and event trees.

Part 4: This part of the presentation describes the mathematical models that can be used for reliability analysis: Markov chains and Petri nets.

Part 5: This part of the presentation discusses the high level methodologies for reliability analysis, such as Root Cause Analysis (RCA), Failure Mode and Effect Analysis (FMEA), and Hazard and operability study (HAZOP).

Part 6: This part gives an overview of software reliability methods, standards, and tools. + Conclusion.


  1. Perfect videos! I liked all of them. Thank you very much for such informative videos.
