Periodic preventive maintenance policy for a two-unit system with failure rate interaction
考虑故障率交互作用的双组件系统周期性预防维护策略

An improvement factor model is first constructed based on maintenance cost,system's age and learning effect to describe the effect of periodic preventive maintenance.Considering the failure rate interaction,an adjustment factor,as a non-decreasing function over the cumulative failure number of one unit,is used to reflect the interaction effect and influence the failure rate of the other unit.The system will be replaced when the times of preventive maintenance reaches N and be operated as minimal repairment ...
