Bathtub curve

The bathtub curve is widely used in reliability engineering and deterioration modeling. It describes a particular form of the hazard function which comprises three parts: * The first part is a decreasing failure rate, known as early failures. * The second part is a constant failure rate, known as random failures. * The third part is an increasing failure rate, known as wear-out failures. The name is derived from the cross-sectional shape of a bathtub: steep sides and a flat bottom.
