【摘要】 对于二维不规则图形零件在排样区域上的最优排列,也就是对二维不规则图形的计算机自动排样算法进行优化的问题。采用矩形包络算法、遗传算法和模拟退火算法相结合,寻找排样件在排样时的最优次序及各自的旋转角度,再用基于“最低水平线”策略的启发式排样算法实现二维不规则图形零件自动排样,从而得到满意的优化排样结果。更多还原

【Abstract】 For the irregular shapes nesting problem in the given nest region of two-dimensional irregular graphics,that is to optimize the computer automated nest algorithm of two dimensional irregular graphics.Rectangle enclosure algorithm,genetic algorithm and simulated annealing algorithm are integrated to look for the best sequence of the shaped parts and each part′s optimum rotation,and "the lowest horizontal algorithm" is used to complete the automatic layout of two dimensional irregular graphical parts in this paper,the satisfactory results of optimal layout have been obtained.更多还原
