Abstract: 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.
