The blue bathtub curve arises from superimposing the brown, yellow and green curves upon each note:
Flattens out in the middle and ascends toward the end of life. A plot of the failure rate over time for most products yields a curve that looks like a drawing of a because of the shape of this failure rate curve, it has become widely known as the bathtub curve. This weibull model is defined with three parameters: The bathtub curve is a failure rate vs.
