Demand Driven Material Requirements Planning: Using The Buffer Status To Schedule Replenishment Orders

Demand Driven Material Requirements Planning argues that production replen-ishment orders should be scheduled on the shop floor according to the buffers’ on-hand inventory. However, the actual performance impact of this remains largely unknown. Using discrete event simulation, this study compares schedul-ing based on the on-hand inventory, with scheduling based on the inventory net flow position. Results of our study show that scheduling based on the former performs best, particularly when multiple production orders are simultaneously generated and progress independently on the shop floor. Our finds give hints that are important to both, industrial practice and software development for production planning and control.
