Abstract: In order to reduce the walking time and improve the efficiency of picking, the simulation environment and model were established in the context of a real logistics center and on the platform of eM-Plant. On this basis, actual data of a warehouse distribution center was used for the study of storage strategy; order batching, routing planning and zone order picking strategy. On the storage strategy, the correlation between materials was taken into account and the software WEKA was used for this purpose. On the way of order batching, two combination methods, based on the order number and based on the item number, were taken into consideration. The simulation result shows that five to eight orders combination way or 50 order items combination way is the best method of order batching. On the routing planning strategy, Z glyph, “8” glyph and new middle path strategy were studied respectively. The results suggest that the new midpoint path strategy is the first choice. On the zoning strategy, the use of dynamic partitioning according to the workload can effectively reduce the waiting time of workers and also increase the collaborative. The proposed methods have applied to a distribution warehouse in practical operation.
