| 摘 要： | 针对集装箱布局提出了一种利用三叉树结构表达三维矩形物体布局状态空间的方法。通过将布避空间依据分割，每次放入相对于当前布局空间来说是满足特定折最优布局块，将该布局块定位于当前布局空间后部的左下角，来完成不同大小的三维矩形全的布局方案的确定，并给出试验结果。

| Abstract: | A heuristic approach to container loading of rectangular objects by using ternary tree structure to represent the packing space is proposed. Through progressive decomposition of the packing space, each time an optimal object that satisfies the specific conditions conforming to the current packing space is chosen and put into the rear bottom left corner of the packing space. Experimental curve of container usage rate versus ratio of the total volume of rectangular packing objects to the overall container volume is obtained. The conclusion drawn from the experimental study is useful to guide the container loading in industrial applications. |
