摘要: 基于匀质块五块排样模式对一类矩形件非剪切排样问题进行了研究.基于动态规划和隐枚举的思想设计了无约束矩形件非剪切排样问题的匀质块五块排样算法.与文献中的矩形件非剪切排样算法的对比试验表明:这种算法能够快速给出问题的最优解,而且可以降低板材切割工艺难度并减少矩形件的分拣成本.与2种矩形件剪切排样算法的对比进一步表明了引入“非剪切”的经济效益.

Abstract: A type of non-guillotine cutting problem of rectangular items was studied based on the use of five-homogeneous-block mode. According to the idea of dynamic programming and implicit enumeration, a five-homogeneous-block cutting algorithm for an unconstrained non-guillotine cutting problem was designed. The comparative experiments with existing non-guillotine cutting algorithms indicated that optimal solutions of the problem could be quickly given by this algorithm, and both the difficulty of plate cutting process and the sorting cost of rectangular items could be reduced. Furthermore, comparisons with another experiment with two guillotine cutting algorithms show the benefits of “non-guillotine”.

Key words: non-guillotine cutting problem, five-block mode, dynamic programming algorithm, implicit enumeration
