Abstract: In order to reduce system unplanned downtime and control product quality, an availability-centered preventive maintenance strategy of the multi-component production system is proposed. Firstly, three preventive maintenance methods are defined, whose influence on the equipment state is studied so as to establish a reliability model. On the basis of Markov state analysis of the system, the relationship between product quality and system degradation state is established, and the total cost model including quality loss cost is constructed. From the perspective of practical application, the reliability and maintainability of equipment are taken into consideration. Thus, an availability-centered preventive maintenance strategy of the system is planned when the goal is to minimize the total cost. Results indicate that the maintenance strategy proposed can be effectively applied to the multi-component production system, and the effect of the multi-operation preventive maintenance method is better than that of single operation.

Key words: degradation system; availability; preventive maintenance; Markov state analysis; quality control
