基于分段编码自动生成产品结构树的研究

Automatic creation of product structure tree based on segment coding

提出了一种基于分段代码自动生成产品结构树的算法。企业的编码分为识别码与分类码,识别码是零部件的惟一标志,往往采用分段的方式进行组织,可按固定段长或分隔符分界分段。识别码的分段信息与零部件在产品结构中的结构信息一致。充分利用编码本身的结构信息解析字符串,具有较强的通用性。此算法已应用于设计研究院的产品数据管理系统中,形成了以设备清单生成产品结构树枝干、以图纸代号生成叶节点的产品结构树自动生成算法。

A new segment coding-based algorithm to automatically creating product structure tree was put forward. The code of enterprises was classified as identity code and classifier code, and the identity code was the unique sign of a part or a component. An identity code was divided into a few of segments by fixed segment length or separate symbol. The segments information in identity code was consistent with the structure information of parts and components in product structure. By making full use of structure information of the code, this algorithm was implemented by means of parsing code string. This algorithm was universal and used in some enterprises' Product Data Management (PDM) systems, which created the branches by device bill and formed the leaves by draft code, so the product structure tree was created automatically.
