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.
随着现代工程的日益复杂化和智能制造技术的广泛应用，产品数据的类型和数量不断攀升，相应的版本迭代速度也不断加快。为了实现对产品数据的有效统一管理和维护，并准确跟踪版本演变，本文提出了一种改进的基于多色图的 BOM 多视图管理和版本控制方法，用于复杂产品。首先，建立了 BOM 多视图管理和版本控制的框架，并详细阐述了其机制。根据多视图版本产品结构模型，讨论了产品生命周期不同阶段的产品结构表示方法。进一步地，引入了多目标约束集，基于改进的多色图建立了版本控制模型，详细说明了其定义和原理。最后，通过应用案例讨论验证了所提出模型和方法的可行性和通用性。
