【摘要】 现代企业面临着快速多变、全球化的市场竞争环境,为了提高企业的竞争力,PDM正以其惊人地发展速度满足不同用户的需求。作为PDM的核心技术:工作流技术更是受到了企业界和学术界的广泛关注与重视。工作流管理系统对提高企业工作的效率、提高协同工作的能力、适应变化的灵活性具有特别重要的意义。 本文主要研究基于PDM的动态工作流管理系统。本文在对工作流管理系统的体系结构、工作模型、工作流引擎、协同工作等方面进行分析的基础上,对网络化工作流管理模式进行了研究,提出了一种分布式工作流服务管理模式。基于上述研究,本文阐述了面向网络化制造的PDM工作流管理系统的部分关键技术,即工作流管理模式、工作流引擎、工作流管理系统的建模工具和基于OPENGL通用格式OBJ的三维浏览器的实现。文中还以一个基于工作流协同工作的项目为例,介绍了工作流的建模、配置、启动过程。 综上所述,本文提出的工作流管理模式和工作流管理系统在PDM中的实施应用方面,具有低费用、能较好的适应于国内企业的管理模式等特点,同时,为进一步实现PDM工作流管理面向动态联盟的协同目标提供了基础。更多还原

【Abstract】 Today the enterprises are confronted with diverse and global marketing competition environment, in order to increase the enterprise competitive capability, PDM are developing surprisingly to satisfy various user demands. As the core technique of PDM, workflow techniques are paid abroad attention and emphasis by the industry and academe group. Workflow management system has significant meaning for increasing the enterprise efficiency, advancing the cooperate work capability and adapting for change.This paper mainly studies the management system of dynamic workflow. Based on the analysis of framework, work model, workflow engine and cooperative work etc. about workflow management system, this paper studies the web workflow management mode and presents a distributed workflow management mode. Based on the study, this paper explains part key technique about web-manufacturing-oriented PDMworkflow management system, that is workflow management mode、 the workflow engine and workflow management system facility of modeling and the three-dimensional browser based on OPENGL general format OBJ. This paper also gives an example of project based on workflow cooperate working to introduce the moduling, configurating and starting process of workflow.All in all, the workflow management mode and workflow management system drought out by this paper is lower cost and can suit for domestic management mode when implementing. And at the same time it is the foundation of further realization of dynamic alliance cooperate goal in PDM workflow management.更多还原
