When the total scheduling time is equal and is the shortest, according to the current position, the distance S1 to the ith target granary and the distance S2 to the jth target granary are respectively, and the distance S3 from the ith target granary to the jth target granary, when S1+S3 is smaller than S2+S3, the scheduling task corresponding to the ith target granary is executed first, otherwise, the scheduling task corresponding to the jth target granary is executed first. Specifically, when the total scheduling time of the two target granaries is equal and is the shortest total scheduling time, a route with a shorter distance from the current position to the two target granaries is selected, the driving distance is reduced, the scheduling route is optimized, and the scheduling time of the whole scheduling flow is reduced.
