摘要: 针对二维板材圆形件剪冲下料问题,提出一种基于四块排样方式的下料算法.这种排样方式将一张板材划分成四个块,在每块中排放具有相同长度和方向的条带;条带中排放若干行同种圆形件.构造排样算法生成单张板材上圆形件的四块排样方式,首先确定圆形件在条带中的布局;然后构造递归算法生成条带在块中的布局;最后采用隐式枚举算法确定板材的最优四块划分.采用列生成算法调用上述排样方法生成多个不同的排样方式,按照单纯型原理择优选择一组排样方式形成下料方案,并对小数解进行圆整操作.使用文献例题和实际生产实例将本文算法与文献算法进行对比,结果表明: 本文算法下料方案板材利用率比四种文献算法分别高0.49%, 0.32%, 6.04%和1.50%, 计算时间能满足实际应用需要.

Abstract: A cutting stock algorithm based on four-block layout was proposed to solve the two-dimensional plate shearring and punching of circular parts. With this layout, a sheet was divided into four blocks. Only the strips with the same direction and length were arranged in each block, and several rows of the same circular parts were arranged in the strips. A four block layout method for generating circular parts on a single sheet by constructing a layout algorithm. Firstly, the layout of circular parts in the strips was determined. Secondly, recursive algorithm was constructed to generate the layout of the strips in blocks. Finally, implicit enumeration algorithm was used to determine the optimal four-block partition. The column generation algorithm was used to call the above layout algorithm to generate a number of different layouts. Based on the simplex principle, a group of layouts were selected to form the cutting plan, and the decimal solution was rounded. The results showed that the plate utilization ratio of the algorithm in the study is 0.49%, 0.32%, 6.04% and 1.50% higher than those of the four literature algorithms, respectively, and the calculation time can meet the needs of practical applications.
