一种备件多级库存系统的仿真模型

Optimal Model on Multistage Stock System of Spare Parts

针对预测性维修(Predictive Diagnostic Maintenance,PDM)策略中维修备件库存优化配置问题,提出了融合故障预测与健康管理(Prognostics and Health Management,PHM)信息的维修备件库存决策方法。在多级库存模型的基础上,建立了基于PHM的维修备件多级库存仿真模型。最后,通过模型求解和Matlab仿真分析,结果表明了基于PHM的维修备件多级库存模型的可行性和有效性。

Aiming at spare parts stock allocation problem under the surrounding of Predictive Diagnostic Maintenance, a new method on spare parts multistage stock system was proposed including the message of Prognostics and Health Management. The PHM-based multistage stock model was built based on model of multistage stock. With the resolving of the model and the simulation by Matlab 7.0., the validity and feasibility of the PHM-based multistage stock model are confirmed.
