Flexible sorting method based on personalized demands of consumers

The invention relates to a flexible sorting method based on personalized requirements of consumers, in particular to a sorting order splitting system for introducing special-shaped cigarette specification optimization based on different periods. When the workdays are major holidays such as the Spring Festival, a specification optimization method based on the item similarity coefficient is introduced, after the specification optimization method is introduced, the number of special-shaped cigarette specifications is reduced from 206 to 103, simulation of the sorting efficiency before and after optimization of the special-shaped cigarette specifications is carried out, and the sorting efficiency of the special-shaped cigarettes is improved by 33.7%; when the sorting efficiency requirement of the special-shaped cigarettes is less than 10000 pieces per hour, fine-standard integrated sorting is adopted; and when the sorting efficiency requirement of the special-shaped cigarettes reaches 10000 pieces per hour, an el
