As the existing condition-based maintenance strategy does not consider the effect of scheduled servicing, the performance deteriorating law cannot be reflected exactly, which is not helpful to give a rational maintenance strategy which combines the scheduled servicing with condition-based maintenance. Aimed at this problem, the performance deteriorating rule and maintenance optimization model under combination maintenance strategy are analyzed deeply. The performance deteriorating model is established by composite Poisson process based on the deteriorating characteristic from the failure mechanism. It describes the maintenance effect of servicing by using intensity function which only restores the cumulative deteriorating values and doesn't have impact on the deteriorating law. And the reliability is also analyzed to obtain the peculiarity of ladder decrease and saltation. On the basis of it, the optimization model is given to determine the optimal servicing period and preventive maintenance thresholds, with an objective to minimize the system cost rate and build a constraint to failure risk. The numerical example demonstrates the cost rate rule with different maintenance strategy values. So the existence of optimal cost rate is proved. Compared with the lifetime, it also shows that the optimal maintenance strategy values can prolong system operational time and control the failure risk. So the system can have high safety grade and a great decrease on the maintenance cost.
