Maintenance Modeling of Remanufacturing Systems in Variable Working Condition with Coupling of Production Scheduling and Reliability
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.
