摘要
产品结构信息是产品数据的核心。提出了用赋权有向图建立产品结构模型的方法 ,用点向量和邻接矩阵表达了该模型的存储结构 ,讨论了将图形模型转换为存储结构的算法。探讨了该模型及其算法的若干应用问题 ,包括从属关系判断、单套件数求解以及产品结构比较等。开发了基于该模型的产品结构管理系统 ,实现了基于产品结构的工艺设计及 CAD/ CAPP/MRP 集成。
Product structure information serves as the core of product data. A methodology of product structure modeling on the basis of weighted digraph was proposed. The storage structure of this model was expressed by node vectors and adjacency matrix. The algorithm of transferring the graphic model into the storage structure was put forward. Detailed application issues of this model and related algorithms, including the solution of affiliation, calculation of the part quantities, and comparison between product structures,were discussed. A product structure management system is developed by this model. Process planning and CAD/CAPP/MRPⅡ integration based on product structure are yielded.
