Abstract

A reliability model of part repairable dual-mode redundant system is established and analyzed using Markov process to satisfy the reliability design requirements of multiple core parts of complex system redundant units. The model considers multi-factors, such as effects of maintenance, fault detection coverage rate, and common cause failure, all of which affect the reliability of redundant system. The model also analyzes two types of redundant system, namely, hot and warm-redundant systems. The relegation work and stop failure states are divided to ensure that the calculations conform to the actual situation. The reliability index of the two types of redundant system is calculated based on the state transition diagram and the equation of the model. As an example, a redundant server in a system is analyzed, results indicate that the redundant design can considerable improve the reliability of the systems. Moreover, fault detection coverage rate and common cause failure have a great influence on the reliability of redundant systems, whereas repair rate has an insignificant influence when the failure rate is low. In the end, this study provides suggestions for the design and improvement of redundant systems.
