Towards Leveled Inventory Routing for the Automotive Industry
Motivated by the success of Japanese car manufacturers, there is an increasing interest in the introduction of leveled logistics concepts. These concepts are characterized by leveled quantities and periodic pick up and arrival times. As a consequence, new requirements regarding the planning of material replenishment result. Planning systems based on the sequential MRP-logic do not take leveling into account and might therefore result in inacceptable volatility. To this end, we propose a modeling framework for leveled replenishment. Building blocks comprise a module for vehicle routing, where cost optimal routes are determined, and inventory control, where leveled quantities are generated. The approach extends the well-known concepts of vehicle routing with respect to the requirements of the automotive industry.
