摘要
延迟制造要求对相同的在制品根据不同的客户需求进行工艺区分.过程质量的不确定性使得传统物料需求计划(Material requirement planning,MRP)难以满足延迟区分的实时性要求.本文简要介绍了面向延迟制造的物料需求计划改进方法,提出了基于累计实时合格率的物料需求计划动态调整方法,开发了实现算法.应用案例表明:该方法能够实时地根据各生产阶段的质量波动对物料需求计划进行动态调整,制定合理的在制品工艺区分决策.
The identical work-in-process （WIP） must be differentiated according to different customization processes for postponement manufacturing. Due to uncertain process quality, it is difficult for traditional material requirement planning （MRP） approach to satisfy the real-time requirement of postponement differentiation. This paper briefly introduces how the MRP approach is adapted for postponement manufacturing at first. A dynamic adjustment approach based on the real-time yield rate is then proposed. The algorithm for implementing the dynamic adjustment approach is also developed. A case study shows that this proposed approach can adjust material requirement plans dynamically according to the realtime quality fluctuation at every stage. As a result, decisions on differentiation for process customization can be made more wisely.
