A reliability prediction model for missile systems based on truncated weibull distribution

Abstract

A reliability prediction model was developed for missile systems based on a truncated Weibull distribution both time and failure truncated cases. In practice, there are usually limited test data available in the development and in most cases test phases of missile systems, and the obtained data are failure and time truncated. Thus in this paper we developed a time and failure truncated Weibull model for reliability analysis of missile systems under development. The central purposes of this model are focussed on the analysis on the present system reliability and the prediction of the system reliability at some future time based on obtained test data. For the purpose of computing, a computer program was developed and have shown the prediction results through a sample problem. This model can be applied to a wide variety of systems not only to missile systems.
