In recent years, with the rapid development of information technology and the expansion of its application range, a variety of ordering systems relying on information platforms and mobile technologies have emerged. This paper researches the ordering system in the college canteen. Aiming at improving college students' status quo of diet and efficiency of canteen dining, a nutrition ordering system without queuing in the student canteen is designed, by constructing a database and combining genetic algorithms.
