Directed Acyclic Graph Version Model Applied in Product Structure Configuration
Tao Li, Wei Feng Sun, Tie-Qiang Ma · 2008
The paper discussed the realization of version management model in product data management. Directed acyclic graph version model is introduced into product structure configuration. The definition and correlative definitions of directed acyclic graph version model are presented at first. Secondly the operations about version model traversing, version consistency analysis, and version tracking etc in version management are analyzed. Then the single product object version model is built. The version management model in product structure configuration is built based on single product object version model. The designer can get needed product structure easily.
