1. shipment plan shipment plan is based on the customer's order preparation. Orders are customers according to their needs for goods to the distribution center issued by the ordering information. Distribution centers need to receive order information to confirm the order information, inventory inquiries and document processing, according to the customer's delivery requirements for the development of delivery schedules, and finally the preparation of the delivery plan.2. Determine the picking method of picking is usually an order to pick, batch picking and composite picking three ways. Order picking by each order to pick; batch picking is a cumulative number of orders into a batch, the number of aggregates after the formation of the picking list, and then according to the instructions of the picking list of a picking commodities, and then classified; composite picking is to take full advantage of the characteristics of the above two ways, and the integrated use of picking in the operation. ① Order picking order picking is for each order, picking personnel in accordance with the order listed goods and the number of commodities, the goods from the storage area or picking area picking out, and then centralized in the picking method. Order picking is a simple operation method, picking can be done immediately upon receipt of the order, the operation lead time is short, and the responsibility of the operator is clear. However, when there are more items, the picking path is longer and the picking efficiency is lower. Order picking is suitable for orders with large differences in size, frequent changes in the number of orders, and large differences in commodities, such as: cosmetics, furniture, electrical appliances, department stores, and high-level clothing. ② Batch picking batch picking is to collect multiple orders into a batch, and then pick according to the commodity category after summing up, and then according to different customers or different orders classified and centralized picking method. Batch picking can shorten the walking time when picking goods and increase the picking volume per unit time. At the same time, because orders are accumulated to a certain number before they are processed at once, there is a lag time. Batch picking is suitable for distribution centers with small changes in orders and stable order quantities, and for the shipment of goods with more regular and fixed shapes, such as boxed and flat-bagged goods. Secondly, the goods to be circulated for processing are also suitable for batch picking, and then batch processing, and then classified distribution, which is conducive to improving the efficiency of picking and processing. ③ composite picking to overcome the shortcomings of the order picking and batch picking mode, the distribution center can also take the order picking and batch picking combined with the composite picking mode. Compound picking that is, according to the variety, quantity and frequency of orders, to determine which orders are adapted to order picking, which is adapted to batch picking, respectively, to take different picking methods. 3. Output picking list picking list is the distribution center will be the customer's order information for computer processing, generating and printing out the picking list. The picking list indicates the storage position and arranges the goods number according to the order of the storage position, so that the operators can shorten the picking path and improve the efficiency of the picking operation. 4) Determine the picking route and assign the picking personnel According to the information of the commodity code and the storage position number indicated in the picking list, the distribution center can make clear the location of the goods, determine the reasonable picking route, and arrange the picking personnel to carry out picking operation. 5) Picking The process of commodity picking can be
