The invention discloses a genetic algorithm-based entity commercial marketing method, which relates to the field of marketing methods and includes the following steps: collecting merchant data and user data; according to the merchant data, setting labels for different consumption types for the merchant, and obtaining merchant characteristic gene establishment Merchant gene pool model; according to user data, user consumption weight is obtained, and user preference model is established; k-means algorithm is used to perform initial clustering of merchant data and user data of similar types; genetic algorithm is used to calculate a certain merchant to be recommended The recommendation rate of the user, and calculate the recommendation rate for the user; then calculate the recommendation rate of the recommended user for the merchant that meets the conditions, and generate a new candidate merchant data set. According to the ranking of each merchant in the data set, the recommended user Precise recommendation; the present invention solves the problem that the current entity commercial market cannot carry out precise marketing to users, which makes it less competitive in the commercial market.

A kind of aluminum alloy recovery and cleaning equipment

ActiveCN112122232BEasy to disinfectEasy to cleanCleaning using liquidsChemicalsRatchetGear wheel
The invention relates to the technical field of aluminum alloys, and discloses an aluminum alloy recovery and cleaning device, which includes a box body, a sliding hole is opened on the back side of the box body, and a rotating shaft A is sleeved on the inner wall of the sliding hole, and the rotating shaft A is located at one end inside the box body The sliding plate is fixedly connected, and the front of the sliding plate is provided with a hole under the rotating shaft A, and the rotating shaft B is sleeved in the hole. The end of the rotating shaft B located on the back of the box is fixedly connected with a ratchet. The ratchet and the spur gear A are arranged in front and back. One end inside the box is fixedly connected with a cleaning cylinder. Through the setting of the cleaning cylinder, the aluminum alloy and cleaning liquid are quantitatively obtained in its fan-shaped groove, so that the content of the cleaning liquid is enough to disinfect and clean the aluminum alloy, and strengthen the disinfection and cleaning of the aluminum alloy. effect, and use the increased weight after containing the cleaning fluid and aluminum alloy to extrude the aluminum alloy, and through the setting of the tooth plate A and other structures, automation is realized without the need for an additional extrusion mechanism Cleaning and disinfection of aluminum alloys and extrusion.
