"Tobacco customers are actually the quantification of the business ability of the tobacco company. Currently, most of the region's tobacco customers are divided into 30 classes. 1 class is the lowest class, and 30 classes is the highest class. If a customer is in the 30th grade, he or she will be able to order more cigarettes of popular brands and new products than customers in other grades. Since each customer orders cigarettes differently each time, big data is used to automatically assess the customer's cigarette business level in the city's ranking and classification. In addition, if the customer is a newcomer to the network, he or she will generally be assigned an initial slot, and will be evaluated later. Of course, the business is different, the level of the initial stall will be different."
