Abstract(s)

Demand Diven Material Requirements Planning (DDMRP) is a manufacturing planning and control system for fast response to customer requirements in varying and volatile demand and supply markets. DDMRP is an extension of the Material Requirements Planning (MRP) approach that explores the principles of Lean and Theory of Constraints production philosophies to reduce manufacturing response time and make good use of manufacturing resources. It achieves this by promoting flow through selective, reduced, and continuously adjusted inventory levels to synchronize manufacturing and supply with customer market demand. Only a few studies compared the performance of both approaches. However, these studies have not fully addressed the relationship between inventory and service levels. Therefore, this research contributes to a better understanding of this relationship by evaluating and comparing the performance of these two approaches in a multi-product, multi-stage production system. The results of a discrete-event simulation study show that DDMRP outperforms MRP regarding the work-in-process and finished-goods-inventory levels required to achieve a given service level.
