An improved polychromatic graphs-based BOM multi-view management and version control method for complex products

With the increasing complexity of modern engineering and wide application of intelligent manufacturing technology, the type and quantity of product data continue to climb, and the corresponding version iteration rate continues to accelerate. In order to achieve effective unified management and maintenance of product data and to track version evolution accurately, this paper proposes an improved polychromatic graphs-based BOM multi-view management and version control method for complex products. Firstly, the framework was established for BOM multi-view management and version control, whose mechanism was also elaborated. According to the model of multi-view-version product structure, the expression method of product structure was discussed at different stages of product life cycle. Furtherly, with multi-object constraints sets were introduced, a version control model was established based on the improved polychromatic graphs, whose definition and principle were also detailed. Finally, application cases were discussed to verify the feasibility and universality of the proposed models and methods.
