Bathtub Curve

Conceptual failure-rate curve with early-life failures, a useful-life period and wear-out failures.

Examples

01The bathtub curve of the new servo motors shows several early-life failures in the first 200 hours, then a long period of few failures.
02Before changing the maintenance strategy, the team checks where on the bathtub curve the conveyor motors are, since replacing them too early adds risk.
03Because the fans are clearly in the wear-out part of the bathtub curve, the team plans to replace them before failures rise further.
