An Optimization Opportunistic Maintenance Policy of Multi-Unit Series Production System

This paper proposes an opportunistic maintenance policy for the multi-unit series production system, which is on the basis of the failure rate analysis. When system halts for performing preventive maintenance or opportunistic maintenance, the alternative decision of replacement and repair is made by economic evaluation of two types of maintenance actions. The optimal preventive maintenance plans in a finite time horizon can be obtained by adjusting the preventive and opportunistic maintenance threshold. A numerical example is given for illustrating the applications of the policy.
