摘要:

针对不规则件排样问题,提出一种应用粒子群算法优化求解的方法。首先以零件的入排交换序列和角度变异序列作为粒子运动速度构造粒子群算法,然后运用剩余矩形动态匹配算法实现解码和局部寻优,并结合不规则件的正交靠接算法实现自动排样。排样实例表明,该优化排样算法是有效的。

Abstract:

 A novel solution for two dimensional irregular part nesting which combined with PSO was presented. Firstly, presenting swapping sequence and variation of angle as velocity of particles to reconstruct PSO for the optimal solution of layout, then using dynamic remaining rectangle matching for decoding the permutation of nesting pattern and orthogonal accessing algorithm to realize automatic nesting. Its effectiveness has been fairly proved in practice.

Key words: irregular part, particle swarm optimization(PSO), dynamic remaining rectangle matching, nesting optimization
