Analyzing the failure rate of a product by using BATHTUB-CURVE. This Bathtub-curve sets an expectation for how a product typically performs over its life cycle. It also represents the failure rate of a product over the time.Failure is the main parameter in automotive industry, every automobile undergoes the minimum failure during production. The optimization of failure rate in manufacturing process byusing different techniques but it was not properly exposed at the delivery stage. After the inspection conducted by the respective company again the failures are occurring after the delivery. During the Transportation from mainhub to sub-hub. The Bathtub-curve sets an expectation for how a product typically performs over its life cycle. And enhance the maintenance process to Lower the failure rate.
