Abstract: To promote the maintenance benefit by combined maintenance, for multi-component systems subjected to condition-based maintenance each component is supposed to endure independent gradual deterioration, and a stochastic deteriorate model is established. The exponential function is applied to set up the reliability functions taking condition parameters as variables. In consideration of imperfect maintenance and probability distribution of maintenance time, a Monte Carlo-based condition deteriorating simulation model of multi-component system is proposed. TA preventive maintenance threshold optimization model is constructed by taking the expected expenses per unit time as the optimization objective, and is verified by a case study. Key
