The real-time monitoring and the high reliability system of multiple components are studied in the mechanical system as background information. The characteristics of copula among multiple component of different systems are considered. The information of affected components is monitoring as covariate. With the prediction model of remaining useful life (RUL)based on stochastic filtering theory, and the strategy of opportunity maintenance, the maintenance decision model of dynamic is studied on the prediction information of remaining useful life. Lastly, the relevant theories are verified by simulation.
