The number of the stock layout results is determined by the number of the stock layout results in S102. For example, if the number of the layout results corresponding to the workpiece group input by the user is determined to be 100, 100 times of layout is performed on all the workpieces, and 100 kinds of layout results are generated.

In the embodiment of the application, N stock layout results are selected from the stock layout results with the target number, and the first sequence of all workpieces corresponding to each stock layout result in the N stock layout results is determined, wherein the value of N is smaller than the target number.

For example, if the target number is 50 and N is 10, the order of all the workpieces corresponding to each of the 10 layout results is determined, and collectively referred to as the first order.

S803: and crossing all the workpieces in the first sequence according to a preset proportion to obtain a second sequence of all the workpieces.

In this embodiment, the preset proportion includes a crossing proportion and a variation proportion, the crossing proportion is used for crossing all the workpieces in the first order according to the preset proportion, and the second order of all the workpieces is obtained after crossing.

For example, if the total number of workpieces is 100, the intersection ratio is 0.1, and the variation ratio is 0.2, then all workpieces in the first order are intersected according to a preset ratio, and 10 workpieces need to be extracted from 100 workpieces, and the order of the workpieces needs to be modified to obtain a second order of all workpieces.

For example, if the target number is 50, N is 10, then the value of M should be equal to or less than 40, and if M is 40, then the directions of all the workpieces corresponding to each of the 40 stock layout results are determined, which are collectively referred to as the first direction.

In the embodiment of the present application, the preset ratio includes a crossing ratio and a variation ratio, the variation ratio is used for performing variation on all the workpieces in the first direction according to the preset ratio, and the second direction of all the workpieces is obtained after the variation.

For example, if the total number of the works is 100, the intersection ratio is 0.1, and the variation ratio is 0.2, then the variation is performed on all the works in the first direction according to a predetermined ratio, and 20 works are extracted from the 100 works and rotated by a certain angle to obtain the second direction of all the works.

S807: and based on the second direction of all the workpieces, performing layout on all the workpieces on the raw material to obtain a second number of layout results, wherein the sum of the first number and the second number is equal to the number of the layout results.

In this embodiment, the second number of layout results is derived from M layout results selected from the target number of layout results according to a variation rule.

For example, if the target number is 50, M is 40, and the first number is 70, then 40 layout results from 50 layout results need to be selected for variation, and 70 layout results are obtained.

In the embodiment of the present application, the sum of the first number and the second number is equal to the number of the stock layout results, for example, the number of the stock layout results is 100, the first number is 40, and the second number is 60.

When M pieces of layout results are selected from the target number of layout results, the layout result with less raw material consumption is preferentially selected.

For example, if the number of the set results is 100, the target number is 50, and M is 50, all of the 50 set results are mutated to obtain 100 set results.
