Modern lean production systems require fast, stable and efficient logistics processes to guarantee just-in-time deliveries of materials to production. For this, a new logistics concept for a plant of the Brose group was developed, which consists of an automatic small parts storage system and an in-plant milk run system. One major challenge was the synchronization of the storage system and the milk run systems in a way that both systems are operated with even utilization and that no obstructions occur between milk run trains. To this end, a timetable was implemented which determines departure times of each milk run train at the warehouse. The timetable takes into account breaks, shift changes and other relevant restrictions. The generation and monitoring of the schedules was implemented entirely in SAP EWM.
