Optimal Policy Research of Preventive Maintenance Period to Series Systems

HU Hai-bao

Abstract

General preventive maintenance model for series system,which considers the dynamic changing rules of failure rate,is used to optimize the maintenance cost.The cost function of a maintenance policy was minimized under given reliability constraint,and the recursion relationship of failure rate before and after preventive maintenance was built up concerning with the concept of age reduction factor.Starting from the results obtained for series systems,this approach can be extended to more complex systems.
