Redundancy-Based Resilience Optimization of Multi-Component Systems

Systems are damaged due to various disturbances, and the reliability of systems is reduced. Measures improve system resilience need be studied since many still operate normally after suffering damage. In this paper, whole process disturbance recovery considered, a optimization model multi-component proposed. Firstly, assessment method proposed based on reliability, loss used as index. Secondly, two component importance indexes, importance, for phase phase, respectively. The indexes weighted obtain so measure change law determine influence degrees components reliability. Then, under constraint maintenance time, an established redundancy strategy maximize resilience. Finally, through example analysis wind turbine with its main components, it verified that can reduce effectively
