Optimal preventive maintenance model based on opportunistic maintenance policy

In order to capture the chance of fault components maintenance in a system,and consider maintenance dependence between the parts in the system,an optimization model which put opportunistic maintenance information into the decision-making of system preventive maintenance was proposed.According to the opportunistic preventive maintenance and preventive maintenance expected benefits plan,The model treats fault time in the system as optimized variables and components maintenance fee rates to get the minimum target to do system preventive maintenance optimization,and make sure parts in different fault source ahead of time the preventive maintenance of the threshold.Finally,the example shows that the effect to preventive maintenance is different under the opportunity thresholds of different fault parts,which can provide strong decision support for the system preventive maintenance.
