Abstract: Existing product structural model cannot express the general and complete product information with high consistency. To deal with this problem, the concept of the product lifecycle structural model and the modeling method were proposed based on analysis of connotation of existing product structural model. The nodes and their relationships of the product lifecycle structural sub-tree were analyzed, the operation methods of the node and its properties were given, and universal transition methods of product lifecycle structural sub-tree were also provided. By using the extended IDEF5 schematic language, six basic operations were described, including the copy node, add node, delete node operation and the set property, add property, delete property operation. Transition rules for different structural sub-trees were discussed. Finally, the entire modeling process was illustrated by instance from the product requirement structural sub-tree to overall product lifecycle structural model.

Key words: product lifecycle, structural model, product model
