AI Technical Summary

Problems solved by technology

[0003] The main defects of the rice vending machine are as follows: First, the machine cannot analyze detailed data such as variety and quantity

Since the rice vending machine only records the total amount of deductions and has no information on the varieties and quantities sold, the machine cannot provide detailed data on the varieties and quantities sold, and cannot perform relevant data analysis

Second, the machine cannot provide a sales method that matches the price and volume

In the traditional hand-cooking mode, the quantity depends on manual experience. The quantity of each dish is different, but the price is the same. Consumers have opinions on this

Third, the machine cannot solve the problem of coexistence of food shortage and waste

Due to the fact that each person’s appetite is different due to the fact that they are sold by portion or by individual portion, some people may not be able to eat enough for a whole portion, while others may not be full. This cannot meet the specific needs of personnel, and it is easy to cause waste.
