【摘要】 现代企业经营环境的变化迫切需要把产品数据管理技术与工作流程管理技术结合起来，特别是把工作流程管理系统运用到PDM系统中来，取代并改进PDM系统中的工作流程管理功能。而工作流程建模方法的选择，则是实现PDM工作流程管理系统的关键。 本文分析了工作流程建模的多种方法：提出了一种扩展Petri网—功能网；并建立了基于功能网的工作流程模型。探讨了这种工作流程模型正确性分析、性能评价及优化方法。利用面向对象分析技术，构造了工作流程管理模型中的流程类、活动类与联系类对象。 通过分析PDM系统与工作流程管理系统的信息交互，初步探讨了工作流程管理系统在PDM系统中的实现技术，提出了工作流程管理系统与PDM系统的集成框架和体系结构，并应用于所开发的洪都集团650研究所的650PDM系统中，实现了工作流程管理系统与PDM系统的集成。更多还原

【Abstract】 As business environment changes, enterprises urgently needs to combine PDM technology with workflow management technology, especially to integrate workflow management into a PDM system to improve the performance of the PDM workflow management function. And the key to implementing the workflow management system in a PDM system is workflow-modeling technology.In this paper, several methods of workflow management are analyzed. An expanded Petri net-function Petri net and the workflow management model based on it are presented. And the correctness analyses, performance appraisement and optimization methods of such a model are discussed. The flow classes, activity classes and relation classes of such a model are also built through the OOA technology.And then, based on the analysis for the information intercommunion between workflow management system and PDM system, the system implementation technology is discussed. And the integration framework and the system architecture are brought forward, and applied to the 650PDM system. In this system, a workflow management system is successfully integrated.更多还原
