针对BTO环境下汽车供应链的敏捷性、精益性需求,提出基于延迟策略、模块化制造的实时排程模型与算法,该模型将一般装配过程分解为简单装配过程,基于简单装配排程的线性搜索算法,迭代生成一般装配过程的排程。再通过设备排程状态与订单工序需求等实时数据进行仿真,仿真结果表明该排程模型及实时算法可以缩短总装提前期,并能保持系统对定制部分操作时间波动的稳定性.此排程模型与算法具有较好的效率,能用于询单、调度和协同等的实时决策支持。

This paper proposes a real-time scheduling model and algorithm based on the delayed different strategy and modularity oriented to the agility and lean character of automotive supply chain. We decomposed general assembly process into ordinary assembly process, and modeled real-time assembly scheduling and proposed the algorithm flow based on the linear search algorithm of ordinary assembly process. The simulation result with real-time data of device scheduling state and order demand shows that the real-time scheduling model can short the dynamic general assembly lead time and keep the stability for operation time fluctuation of customized components, and the algorithm is so efficient that it can support real-time decision in order quotation, dispatch and coordination.
