One method about irregular shapes is approximately rectangle solution method based on regular shapes packing , the other method is to deal with the irregular shapes directly . this paper presents a new approximation optimal about the packing space based on the combination of the two methods . using this algorithm , we can improve the packing efficiency and the using ratio of material
本文针对生产实际中的下料方案问题，在原有矩形近似算法和不规则件直接处理算法的基础上，探索了一种基于两种方法相结合处理二维不规则件的近似优化方法，以提高排样的效率和材料的利用率。
