The two scheduling rules may be applied alternatively or simultaneously, but it should be noted that, if rule 1 exists, rule 1 is applied as the highest priority of task scheduling, that is, task scheduling is performed according to delivery time in sequence.
Before step S1, the tool changing number and the tool changing time of each order task need to be initialized, that is, the tool changing number a =0 and the tool changing time t =0, if a batch order processing task arrives, the arrival time and the appointed delivery time are recorded, and according to the current order processing task information, a task set and an initialization sequence P = { P } can be defined 1 ,p 2 ,...p j ,p n In which p is j N is the total number of all order processing tasks, which is the jth processing task in the initial sequence among all order processing tasks.
In a possible design of step S1, grouping and sorting a plurality of order processing tasks of a longitudinal line based on a first task scheduling rule to obtain a plurality of task subsets, including:

(3) And determining the tool changing number and the tool changing time of each processing task according to the reusability of the tool between every two order processing tasks.
In one possible design, before the tool changing number and the tool changing time of each processing task in each task subset are determined according to the tool changing scheduling rule, the method further comprises the following steps: and calculating the average residual life of each group of cutters, reserving each group of cutters with the average residual life higher than the threshold value according to the priority sequence of the average residual life from high to low, and replacing each group of cutters with the average residual life lower than the threshold value.
Wherein, it should be noted that, for each set of tools that can be reused for the next order processing task, the average remaining life of each set of tools is calculated according to the remaining life of all the tools in each set of reusable tools, and the higher the average remaining life is, the higher the priority is; reserving the cutter set with high average residual life and replacing the cutter set with low residual life by setting an average residual life threshold; wherein, the calculation mode of the residual service life of each cutter is as follows: the accumulated use times/the preset accumulated use times or the accumulated use time/the preset accumulated use time.
