【摘要】：为构建一个全面高效的新产品设计配置模型,文章建立了基于多维关联规则的零部件约束数据库。由产品质量特征重要度的计算和待配置零部件集合设计结构矩阵的撕裂操作,来指导产品族物料清单(bill of material,BOM)树上零部件的重要度排序;建立映射矩阵将新产品的总体质量特征需求分解为对产品族BOM树上特定零部件的功能技术特征,通过余弦夹角相似计算从零件库中检索出相匹配或近似匹配的候选零部件;按照零部件对新产品的重要度排序,通过多维关联约束驱动和迭代匹配,逐步形成各零部件的总体候选方案;同时确定待改型设计和新设计的零部件,根据综合匹配度计算确定最优匹配方案。最后通过实例说明了该方法的可行性。
[Abstract]:In order to construct a comprehensive and efficient new product design configuration model, a component constraint database based on multi-dimension association rules is established, which is based on the calculation of the importance of product quality characteristics and the tearing operation of the structural matrix of the set of components to be configured. To guide the importance ranking of components on the product family bill of material (BOM) tree, and to establish a mapping matrix to decompose the total quality requirements of the new product into the functional and technical features of the specific parts on the BOM tree of the product family. According to the importance of the parts to the new products, the candidate parts are retrieved from the parts library by the similarity calculation of the cosine angle, and driven by multi-dimensional association constraints and iterative matching, according to the importance of the parts to the new products. The overall candidate scheme for each component is gradually formed, and the parts to be modified and newly designed are determined at the same time, and the optimal matching scheme is determined according to the calculation of the comprehensive matching degree. Finally, the feasibility of the method is illustrated by an example.
