Episode notes
Constant Failure Rate Models
- Constant failure rate models liken failure to radioactive decay or accidents like dropping a coffee mug.
- Few systems actually have failures independent of age, unlike coffee mugs or naked mole rats.
Naked Mole Rat and Reliability
- The naked mole rat is rare in biology because it does not age or accumulate damage.
- It has a constant risk of death from external factors independent of age, analogous to constant failure rate systems.
Failure Mechanisms vs System Aging
- Electronic component failure mechanisms like electrostatic discharge cause constant failure rates independent of age.
- However, entire devices accumulate damage and wear out, invalidating simple constant failure rate assumptions.
