- 摘要:
- 大规模矩形件优化排样是一个典型的组合优化问题,属于NPhard问题.实际工程中对一个排样方案一般有满足“一刀切”的工艺要求,“一刀切”要求增加了对排样的约束. 提出的优化算法,将矩形匹配分割算法作为遗传算法染色体的解码器实现一个排样方案,用遗传算法进行排样方案的全局搜索.算例比较表明,该算法可以求得满足 “一刀切”约束的最优解.
- Abstract:
- The optimal layout of large scale rectangular parts is a combinatorial optimizat ion problem, a typical NPhard one. In practical engineering, quire cutting is o ften requested, which increases the constraints in the determination of a layout . To satisfy quire cutting requirements, in this paper, an optimization algorith m is proposed wherein a rectangular matching and segmentation algorithm is emplo yed as a decoder of chromosomes in a genetic algorithm to determine placement. A global optimal solution for placement can be achieved with this genetic algorit hm. Simulation results confirmed the validity of the proposed algorithm.
