摘      要：This paper presents an imperfect maintenance strategy for the multi-component *** proposed maintenance strategy takes into account two types of maintenance actions,namely preventive maintenance(PM)and corrective maintenance(CM).The imperfect effect of PM is modeled on the basis of the hybrid hazard rate ***,a new structure importance measure based on the survival signature is *** this new importance measure method,an adjustment function is designed to update the PM maintenance *** CM actions,a decision rule relying on the criticality level of components is *** order to judge the criticality level of components,a novel structure updating method based on the survival signature is ***,a maintenance model considering economic dependence among components is developed.A 10-component system is finally introduced to illustrate the use and advantages of the proposed maintenance strategy.
