摘要:Redundancy architecture is known as an important and effective method for improving reliability. In particular, a 2-component standby redundant system is one of the most fundamental and important redundant models in the reliability theory. In some previous investigations, a 2-component standby redundant system with priority has been considered and then the mean time to failure (MTTF), variance of failure time (VOFT) and reliability function in the system have been evaluated based on limited stochastic information about each component. In this study, we address a preventive maintenance to the system based on the outcomes in the previous investigations. In particular, the digital SC twin framework is presented.
