For a vehicle or repairable system, incidents (conditions) are neither necessarily independent nor identically distributed. Therefore, traditional statistical distributions like Weibull, Normal, etc., are no longer valid to estimate reliability. The Non-homogeneous Poisson process (NHPP) model can be used to predict reliability and warranty of the field product. It can also measure the reliability improvement during the development cycle. Repairable system can show a decreasing failure rate (ß<1) when reliability is improved by progressive repair. It can also show an increasing failure rate (ß>1)when wearout failure modes of components begin to predominate.
