摘　　要：针对变工况下的多工序再制造系统,提出生产、设备衰退和系统维护之间的耦合建模方法.首先引入考虑设备可靠性的动态生产优先级并据此生成生产调度计划,进而基于变动生产计划建立设备的变工况故障率模型,在此基础上,考虑生产的动态性和设备衰退的不确定性,构建基于双生产周期优化的再制造系统动态维护决策模型.算例分析表明,该模型可有效提高系统生产净收益且相对于传统生产和维护决策方法更具优势.For the multi-process remanufacturing system under variable working conditions,a modeling method considering the coupling among equipment deterioration,maintenance,and production is proposed.First,a dynamic production priority considering equipment reliability is introduced,based on which,a production scheduling plan is generated.Then,an equipment hazard rate model under variable production plan is established.On this basis,a dual-cycle dynamic maintenance decision-making method is constructed,considering the dynamic nature of production scheduling plan and the uncertainty of equipment failure.The illustrative example shows that the model can effectively improve the net profit of the system and has more advantages than traditional production and maintenance decision-making methods.
