What’s All the Fuss about Bayesian Reliability Analysis?

The term Bayesian Reliability Analysis is popping up more and more frequently in the reliability and risk world.  Most veteran reliability engineers just roll their eyes at the term.  Most new reliability engineers dread the thought of having to learn something else new, just when they are getting settled in the job.  Regardless, it is a really good idea for all reliability engineers to have a basic understanding of Bayesian Reliability Analysis.

This series explains Bayesian Reliability Analysis and justifies Continue reading “What’s All the Fuss about Bayesian Reliability Analysis?”

No Evidence of Correlation: Field failures and Traditional Reliability Engineering

Historically Reliability Engineering of Electronics has been dominated by the belief that 1) The life or percentage of complex hardware failures that occurs over time can be estimated, predicted, or modeled and 2) Reliability of electronic systems can be calculated or estimated through statistical and probabilistic methods to improve hardware reliability.  The amazing thing about this is that during the many decades that reliability Continue reading “No Evidence of Correlation: Field failures and Traditional Reliability Engineering”
