为充分利用前人的经验以及有效地提高钢产品包装工艺规划的速度,提出了一种基于实例推理的钢产品包装工艺检索方法。基于钢产品包装工艺实例库,提出了2 层次的实例检索,第1 层采用层次编码来检索出相同包装代码下的包装工艺实例集;在第2 层检索中计算钢产品包装零件类型、材质特征以及几何尺寸的相似度,来逐步过滤掉不符合要求的实例,从而获得工艺最相似的包装工艺。通过具体的实例验证了该方法的有效性。

To make full use of previous experience and effectively improve the speed of steel product packaging process planning, a retrieval methodology of steel product packaging process based on case-based reasoning was proposed. Based on the case library, a two-stage retrieval method proposed. In the first stage, the set of the packaging process instances in the same packaging code were retrieved through encoding products. In the second stage, the most similar case was retrieved by calculating the similarity of steel product packaging parts type, material characteristics and geometric dimensions, and gradually filtering out unqualified cases. The effectiveness of this methodology was verified with real cases.
