The Reliability Growth platform models the change in reliability of a single repairable system over time as improvements are incorporated into its design. A reliability growth testing program attempts to increase the system’s mean time between failures (MTBF) by integrating design improvements as failures are discovered.
The Reliability Growth platform fits Crow-AMSAA models. These are non-homogeneous Poisson processes with Weibull intensity functions. Separate models can accommodate various phases of a reliability growth program.
