However, in the current "person-to-person" mode, in order to increase the rate of flow of the goods and the efficiency of sorting, the racks are usually provided with multiple levels of storage locations, each level housing a plurality of different types of goods. Similar sorting systems suffer from several drawbacks, one of which is that, when a single item in an order is fulfilled, the AGV needs to carry the entire rack containing that type of item, causing excessive consumption of resources, and the item easily drops off the rack while the AGV is moving at high speed. Secondly, because every type of goods on the goods shelves are placed in a small quantity, the goods shelves have high replenishment frequency, and occupy extra warehouse operation space. Thirdly, when the orders contain multiple types of required goods, the system needs to distribute the corresponding number of AGVs to fulfill the orders cooperatively, and more AGVs in the working area put higher requirements on the computing capacity of the central dispatching system.

Aiming at the AGV order picking mode, a queuing network analysis model is adopted to illustrate the operation process of the whole storage system. Referring to fig. 7, a semi-open queuing network (SOQN) model established for the warehousing system is shown. The order arrival accords with the Poisson process lambda, one order arrives at the system and waits for being matched with one AGV in the AGV list, and the process is synchronous operation in the model. When an AGV is assigned an order, the AGV moves from the stop point to the target material depository (operation 1), and because there is no wait time, the process is modeled in the model as an infinite helpdesk situation. Operation 2 models the process of an AGV waiting and receiving a material inventory to launch an order commodity, modeled as a single helpdesk case. The SOQN model considers both the case of a single commodity and the case of multiple commodities in an order, and is modeled as a geometric distribution g, namely: probability g has a single item, probabilities 1-g have multiple items, with an average of 1/g item per order. Operation 3 is modeled as the AGV moving from the position of the last completed material depositor to the packing table.
