| 英文摘要: |
| The artificial layout of rectangular plate of low efficiency and time-consuming could not be guaranteed to get a
high optimum plate utilization program. By studying the process of artificial layout of rectangular plate, an connective
algorithm of cutting stock system processes and heuristic with genetic for the layout of rectangular plate was put forward.
The results show that it can make full use of raw materials storehouse and trace material storehouse, and it can avoid
generating more trace materials by using the designed system processes. It can quickly search for the approximate overall
optimal project of the layout by using the designed algorithm of heuristic combinations with genetic for rectangular plate.
The design scheme can improve the utilization ratio of sheet metal, and it can reduce the production of more residual
materials. |
