A version management model of PDM system and its realization
摘要
Abstract
Based on the key function of version management in PDM system, this paper discusses the function and the realization of version management and the transitions of version states with a workflow. A directed acy-clic graph is used to describe a version model. Three storage modes of the directed acyclic graph version model in the database, the bumping block and the PDM working memory are presented and the conversion principle of these three modes is given. The study indicates that building a dynamic product structure configuration model based on versions is the key to resolve the problem. Thus a version model of single product object is built. Then the version management model in product structure configuration is built and the apphcation of version manage-ment of PDM syste' is presented as a case.关键词
