Dynamic Adjustment of Material Requirement Planning for Postponement Manufacturing
面向延迟制造的MRP动态调整方法研究

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 real- time quality fluctuation at every stage.As a result,decisions on differentiation for process customization can be made more wisely.
