Proper maintenance schedule is required to improve manufacturing systems’ profitability and productivity. A novel dynamic maintenance strategy is thus developed to incorporate both the single-machine optimization and the whole-system schedule for series–parallel system. Firstly, multiple attribute value theory and maintenance effects are considered in the single-machine optimization. A developed multi-attribute model (MAM) is used to determine the optimal maintenance intervals. Then, a series–parallel structure of the system is investigated in terms of the whole-system schedule. Maintenance time window (MTW) programming is presented to make a cost-effective system schedule by dynamically utilizing maintenance opportunities. The maintenance scheme achieved by using the proposed MAM–MTW methodology is demonstrated through a case study in a hydraulic steering factory. It is concluded that proper consideration of maintenance effects and time window leads to a significant cost reduction.
► A dynamic maintenance strategy is developed for series–parallel system.
► Multiple attribute value theory and maintenance effects are considered.
► Maintenance time window programming makes a cost-effective system schedule.
► The information transfer in decision-making layer is not a “push” process, but a “pull” process.
► Proper consideration of maintenance effects and time window leads to a cost reduction.
