Acceleration Factor Modeling

  • J. W. McPherson


In reliability physics and engineering, the development and use of the acceleration factor (AF) is fundamentally important to the theory of accelerated testing. The AF permits one to take time-to-failure (TF) data very rapidly under accelerated stress conditions, and then to be able to extrapolate the accelerated TF results (into the future) for a given set of operational conditions. Since experimental determination of the AF could actually take many years, the AF must be modeled using the TF models introduced in Chap.  5. Since the AF must be modeled, it brings up another important question—how does one build some conservatism into the models without being too conservative?
