Abstract: For the two-unit serial system in remanufacturing environment,the interaction model of product quality and machine components deterioration was built by integrating the normal product flow and the recycled product flow.Then the influence of the machine productivity change caused by the change of the recycled products’ quantity on machine deterioration was introduced,and a quality-driven machine failure rate model considering variable productivity was established.On this basis,the dynamic opportunity maintenance strategy of two-unit serial system in remanufacturing environment based on cost saving function was proposed.The analysis of the example showed that the model could effectively reduce the total maintenance cost of two-unit serial system in remanufacturing environment,and it could provide effective technical support for the maintenance management of remanufacturing enterprises.
