Demand Driven MRP - Nuevo método para la gestión de la Cadena de Suministro: un estudio de caso

Demand-Driven Material Requirements Planning (DDMRP) methodology was developed to increase ma-terial and information flow and enhance the competitive advantage of manufacturing and distribution companies. Some researchers have developed models to simulate the performance of DDMRP, neverthe-less, there were no studies found in the literature that analyzed the implementation of this methodology in a company. The present work, therefore analyzes the evolution of a company after converting from MRP to DDMRP and the impact of this process on material management. The results clearly show that using DDMRP the company increased visibility in the supply chain by re-ducing considerably the bullwhip effect and rush orders. Importantly, in the months following the imple-mentation the inventory level was reduced by more than 24% while material consumption was increased by almost 14%. Throughout the entire process, the company maintained the high service level that it had had before. Keywords : DDMRP; Inventory, Visibility, Forecast, Uncertainty.
