摘　　要：介绍了产品物料清单演化历史追踪的内涵,总结了相关研究工作,指出了基于版本的产品物料清单演化历史追踪存在的问题。介绍了数据起源的相关概念,给出了数据起源和产品物料清单的数学模型。在实例物料起源标注设计和建模的基础上,针对三种典型的物料清单演化历史追踪需求,给出了产品物料清单起源追踪模型。与基于版本管理的产品物料清单起源追踪相比,基于实例物料起源标注的产品物料清单起源追踪不但能显著减少物料清单版本快照数据的存储量,而且能克服版本管理存在的版本向上蔓延问题。Connotations of evolution history of product Bill of Material（BOM）tracking were introduced and the relevant work was summarized.Shortcomings of version-based data provenance tracking was discussed.Then,the related concepts of data provenance were introduced and the mathematical model for data provenance and product BOM was constructed.Finally,based on design and modeling of the provenance annotation of instance materiel,the modeling of provenance annotation-based data provenance tracking of product BOM was analyzed respectively corresponding to three typical tracking demand.Compared to version-based data provenance tracking,provenance annotation-based data provenance tracking of product BOM could not only significantly reduce the storage of BOM version snapshots but also overcome the upward spread of version.
