Study on combined software and hardware reliability growth model for avionics system

Modern digital avionics system consist of hardware subsystem and software subsystem, in which there are some characteristics: interaction, real time and so on. In this paper, several combined HW/SW system reliability models published are summarized. A new combined HW/SW system growth model based on Markov processes is presented. How to solve the problem of reliability growth for both hardware and software during the development phase is described. This model could be applied to predict and evaluate the reliability and availability for combined HW/SW computer control system.<
