PDM中基于工作流的电子仓库和文档管理

Data Vault and Document Management in PDM Based on Workflow

产品数据管理的各功能模块都与文档管理密切相关,因此文档管理模块是产品数据管理的基础模块。系统采用J2EE平台技术,构建了该产品数据管理系统的三层体系结构。论文首先讨论了文档管理与电子仓库的关系,介绍了工作流程中文档从生成到归档的全过程,构建了文档管理的状态图和文档操作的功能模型,从而说明了文档管理动态描述产品设计的过程。其次论述了文档版本管理的实现,建立了文档版本管理的流程图。最后给出了产品数据管理的文档管理系统的一个实际应用案例。

Almost all modules of PDM system have direct relationship with the document management, so the document management is an elementary module of PDM system. Adopting J2EE platform technology, three-tiered architecture for PDM system is developed. At first the relationship of data vault and document management system is discussed. Documents' evolvement from generating to archiving with workflow is introduced. The status chart of document management and the functional model of document operation are constructed. All of these explain how the document management describes the process of production design dynamically. Then the realization of document version management is discussed, and the flow chart of version management is illustrated. Finally an application of PDM system's document management system in Harbin Electric Machinery Ltd. is presented as a case.
