Abstract:

Servicing is seen as an important means to retain product state and lower failure frequency. This study analyzes the impact of servicing on product state and failure rule. The composite Poisson process is used to model the servicing effect, so as to obtain the life distribution of a product for the case of scheduled servicing. Based on the life distribution, a maintenance strategy is proposed which combined the benefits of scheduled servicing and condition-based maintenance. The optimal servicing period and preventive maintenance threshold are determined through optimizing the operation cost in the maintenance strategy. Finally, the simulation result shows that this maintenance strategy can prolong the product time between maintenances, so that the number of maintenances can be considerably reduced in its whole life cycle. It also shows a great decrease on the whole life cycle maintenance cost.

Key words: maintenance strategy, scheduled servicing, condition-based maintenance, composite Poisson process, optimization
