“Wave” management is also known as distribution operation. It classifies orders through rules and screens “Picking Lists”. The quality of wave creation is related to cargo efficiency. Each wave contains multiple “Orders”, and each order may have multiple “Order Lines”, that is, the number of SKUs, which can generate one or more picking lists, namely wave lists. Waves are essentially a combination optimization of order pools based on some rules. The system automatically completes wave arrangements, generates picking instructions and sends them to PDAs (handheld computers), and pickers receive distribution tasks with one click.
There are some general principles for creating total picking waves: reduce necessary walking, reduce handling, reduce searching, and avoid duplication. Common methods: The system prioritizes the sorting of goods according to the ABC classification of the goods. The Class A products in the self-operated warehouse are concentrated in 10%~20%. The whole box storage, large pieces, and piece picking are divided into partitions. PCB analysis is carried out by whole box and pallet delivery; Set different wave strategies for SKUs to decide which orders can be placed in the same wave: EIQE analysis, using order items, product specifications, product quantity and distribution channels to analyze warehouse and distribution delivery characteristics; separate pre-order and post-order orders into waves; the efficiency of the sowing method (picking by batch) is generally higher than the fruit picking method (picking by order), and those who can convert the fruit picking method into the sowing method must try their best; merge orders with high product overlap rates for picking, and scattered orders can be picked and sorted at the same time; large warehouses are picked in waves, and superimposed by zone picking. Cross-border orders usually have fewer order lines, most of which are single items, and the picking list can be 50~100 orders/sheet.
