Performance Analysis of Picking Routing Strategies in the Leaf Layout Warehouse

The routing strategy for order picking is an important factor in the efficiency of warehouse picking, and improvements to layout provide more options picking. number storage locations be visited during operation also has impact on selection strategies. In achieve effective improvement operations distribution centers, this paper focuses leaf based previous single-command extends it study multi-command strategy, which three heuristic strategies, S-shape, return, composite, are introduced solve walking distance problem operations, with different numbers visited. Based equation between any two warehouse, travel models corresponding strategies constructed, cuckoo search algorithm calculate composite experiments. addition, computational experiments path carried out according operation. By analyzing numerical results, we find that best overall results among average values optimization rates exceeding 30% (the S-shape) 40% return), respectively. At same time, return outperforms S-shape when less than seven. As increases, gradually strategy. From a managerial practical perspective, compared focus current research, studied relevant actual situation merging warehouses can effectively improve competitiveness enterprises, customer satisfaction e-commerce enterprises.
