This paper proposes an Opportunistic Maintenance (OM) model for multi-station serial-parallel remanufacturing systems with interaction between production schedule and station reliability. A dynamic-priority-based production scheduling method is firstly introduced by involving the impacts from both the different types of recovered products and the deterioration of stations. This method is an important supplement for the remanufacturing system to describe the distinctive interdependence among the deterioration of the system, the production schedule and the maintenance activity. Then, a two-production-cycle-based OM policy is developed on stochastic programming, with the uncertainty incurred from the recycling market and the distinctive interdependence involved. Finally, numerical comparisons based on the remanufacturing scenario of the engine crankshaft are illustrated to show the availability of the proposed OM model.

多站再制造系统的维护建模与生产计划和站可靠性之间的相互作用

本文提出了一种多站串并行再制造系统的机会维护（OM）模型，该模型具有生产进度和站可靠性之间的相互作用。首先引入了一种基于动态优先级的生产调度方法，该方法考虑了不同类型回收产品和站点劣化的影响。该方法是对再制造系统的重要补充，可以描述系统的劣化、生产进度和维修活动之间独特的相互依赖关系。然后，基于随机规划制定了基于两个生产周期的 OM 策略，其中考虑到回收市场带来的不确定性和独特的相互依赖性。最后，基于发动机曲轴再制造场景的数值比较表明了所提出的 OM 模型的可用性。
