For example, considering the "purchase" behavior alone may ignore interactions of the "browse" or "join shopping cart" behaviors. Integrating all behavior patterns provides a more comprehensive correlation analysis.
Assume that there are two commodities: commodity i and commodity j, during a certain period of time t, the user may perform the following three operating states for both commodities: purchase (B), browse (V), and join shopping cart (a).
In this scenario, all possible state combinations for commodity i and commodity j are as follows:

The technical scheme uses the cargo association degree model to optimize the layout of the cargoes in the warehouse, collects and analyzes data, collects behavior data of different cargoes in the warehouse, and comprises browsing, adding shopping carts and purchasing; calculating the relevancy of cargoes, applying a cargo relevancy model, measuring the relevancy of two cargoes by comparing the ratio of the behavior probability between the cargoes to the independent behavior probability, sorting the relevancy of the cargoes and distributing the cargo space, sorting the cargoes with predicted sales, and screening out the first 50% with higher sales and the last 50% with lower sales respectively; calculating the association degree between the front 50% of high sales goods and the rear 50% of goods; matching the goods with the highest sales ranking in the last 50% according to the association degree and sales, and carrying out cargo space distribution; the low sales volume goods with high association degree are distributed to the idle goods space close to the high sales volume goods, so that the distribution efficiency and the convenience of purchasing various goods by customers are improved; the goods picking efficiency is improved, and the goods with high relevance are placed at the positions close to each other, so that the moving distance during goods picking is reduced, and the goods picking efficiency is improved; optimizing warehouse space usage: the reasonable goods layout enables the hot goods to be more easily accessible, ensures the logic placement of the related goods, and effectively utilizes warehouse space; based on dynamic adjustment of data, the scheme allows the association degree and the position of goods to be updated and adjusted periodically, so that the strategy has the flexibility of dynamic adjustment to cope with the change of market and consumption behavior; in general, through intelligent analysis and strategic goods space arrangement, the technical scheme not only improves the efficiency of warehouse operation, but also can enhance the purchase experience of customers and increase sales, and is a warehouse management solution with improved comprehensive performance.
In one embodiment of the present invention, a logistic warehouse management method, when delivering goods, determines a goods delivery sequence according to order picking time within a preset time interval, includes:
When a plurality of orders are received in a preset time interval, acquiring picking time of each order;
Shipping orders in a preset time interval according to the order picking time sequence from less to more;
and sending the carrying instruction to the goods picking equipment, wherein the goods picking equipment picks goods sequentially.
And determining whether the goods delivery sequence is when the free picking equipment is not in the warehouse or is first served according to first come first served in the preset time interval according to the order picking time, and referring to the following time interval model when the free picking equipment is not in the warehouse.
T=min(Tb+α·ln(1+N)+β·ln(1+M),Tmax)
Where T is a preset time interval, T b is a base time interval, which is a minimum time interval that the system should hold regardless of the number or size of orders, the base time interval can be set to be the average time that the AGV trolley processes an order, α is an adjustment factor related to the number of orders, N is the total number of orders currently pending, β is an adjustment factor related to the average number of goods of the orders, M is the average number of goods of all orders currently pending, and T max is a preset maximum time interval.
The working principle and the effect of the technical scheme are as follows: according to the technical scheme, the order processing flow is optimized, so that the warehouse can process and ship orders more efficiently, order information is collected, information of each received order is collected by the system in a preset time interval, the picking time is calculated and ordered, the complete picking time required by each order is calculated, and the complete picking time is based on factors such as the positions and the quantity of commodities in the order and relevant picking paths; ordering the collected orders according to the time required by picking from less to more; order shipment optimization, in which orders with short pick times are preferentially processed according to the ordering of pick times. This means that orders requiring less time to prepare can be placed first, thereby improving overall shipping efficiency; The system automatically sends the order of pick to a pick device, such as an automated pick robot or a conventional picker; the picking device or person will perform the picking operation in accordance with the instructions of the system. The processing speed is improved, and the processing speed of the whole order is improved by optimizing the processing sequence of the orders, namely preferentially processing the orders with shorter picking time; improving customer satisfaction, faster order processing speed generally means that the customer can receive the goods faster, which directly improves customer satisfaction; the efficiency is improved, the clear order of picking reduces the purposeless movement of equipment and personnel in the warehouse, reduces the time waste and improves the overall efficiency of picking. The error rate is reduced, and the system automation instructions reduce errors caused by human factors, such as picking out goods or missing certain orders; Resource optimization, reasonable time ordering and machine scheduling allow more efficient use of warehouse resources, including employee time and use of mechanical equipment. The structured operation is promoted, the structured level of the operation is promoted by the unified and automatic processing flow, and the confusion and uncertainty in the operation are reduced. In a word, the technical scheme ensures that warehouse operation is more efficient and systematic by intelligently optimizing the order processing sequence, thereby remarkably improving the processing speed and the customer service quality and realizing higher operation efficiency and lower error rate; calculating a current time interval using the provided formula, wherein T b is the lowest base time interval that the system should maintain when the order quantity is minimal, the parameter α controls the effect of the order quantity (N) on the interval, and β controls the effect of the average cargo quantity (M); ordering orders within this time interval from less to more according to the items of the load location information to generate a shipping order that minimizes the average shipping time in the event that the AGV cart resource is limited and cannot immediately respond to the user's request for order placement, significantly reducing the average shipping time of orders by ordering orders within this time interval from less to more according to the items of the load location information, since less of the load information is preferentially processed, they leave the system faster, resulting in a reduction in the number of orders waiting to be shipped and the average shipping time for all orders; the shorter operation can process more operations in unit time due to the fact that the operation is completed quickly, and therefore the throughput of the system can be improved; Reducing the cumulative delay of orders, the early completion of orders means that tasks that subsequently rely on those orders can begin early, shortening the cumulative delay in the order flow; improving the user experience, a system that sees a fast response would have a better experience for the user, which is especially important for applications that require interactive responses.
