Episode notes
Embrace Randomness in Failures
- Failure times of identical components vary due to invisible manufacturing differences.
- This randomness is natural and must be embraced in reliability engineering.
Probability and Reliability Curves
- Probability density and reliability curves visualize failure likelihood and survival over time.
- These curves represent the same info but aid different types of analysis.
Mean Time to Failure Misleading
- Mean time to failure balances the probability density curve but doesn't reflect reliability accurately.
- Different failure mechanisms produce distinct signature curves despite sharing the same mean.
