【摘要】：近年来,由于企业生产数据更新速度不断加快以及产品生产过程日益复杂,同时面临着来自外部企业的激烈竞争,急需一种产品数据管理(Product Data Management,简称PDM)系统来帮助企业进行产品数据信息共享和产品生产过程管理,以此来提高企业产品设计研发效率,进而大大提升企业的外在竞争力。在实际的企业生产中,产品设计研发过程大多是以项目为基础单位进行管理的,因而项目管理在PDM系统中的作用日益受到人们的关注,然而目前国内绝大部的PDM软件在项目管理方面的功能还不够完善,本文以研究室自主研发的PDM系统为背景,针对企业实际项目管理需求,通过工作流模型技术和工作流引擎设计,总结出一种基于工作流技术的项目管理设计模式,并从项目的任务机制,以及企业项目管理中所发生的项目流程变更等不同情况进行全方位的解读。重点介绍了在项目流程变更中的一种修正型变更,即项目任务变更,同时包括在进行任务变更时任务数据的变更,包括任务数据恢复和数据修改等内容。文章首先分析了企业关于项目管理的实际需求,包括共性需求和针对企业实际操作管理中产生的个性化需求;其次,详细介绍了保证项目管理推进的工作流机制,包括工作流的过程定义和工作流实例化算法以及工作流引擎推进方式;最后,介绍了针对企业实际项目管理需求所产生的任务推送模型和项目任务变更设计,阐释了类设计和数据库设计。在文章的末节,介绍了开发平台和数据库的选择,并通过最终的实例效果演示,直观的呈现出整个项目管理的功能和实际应用情况。
[Abstract]:In recent years, due to the increasing speed of updating production data and the increasing complexity of product production process, enterprises are facing fierce competition from outside enterprises. A product data management (PDM) system is urgently needed to help enterprises share product data information and manage product production process, so as to improve the efficiency of product design and research and development, and thus greatly enhance the external competitiveness of enterprises. In the actual production of enterprises, the process of product design and development is mostly based on project management, so the role of project management in PDM system has been paid more and more attention. However, at present, most of the PDM software in China is not perfect in project management. This paper is based on the PDM system developed by the research room, aiming at the actual project management needs of enterprises. Through workflow model technology and workflow engine design, a project management design pattern based on workflow technology is summarized. And the enterprise project management in the project process changes and other different situations are interpreted in all directions. This paper mainly introduces a kind of modified change in project flow, that is, project task change, including task data recovery and data modification, etc. This paper first analyzes the actual requirements of the enterprise on project management, including the common needs and individualized requirements arising from the actual operation management of the enterprise. Secondly, it introduces the workflow mechanism to ensure the advancement of the project management in detail. It includes workflow process definition, workflow instantiation algorithm and workflow engine push mode. Finally, the task push model and project task change design are introduced. Class design and database design are explained. At the end of the article, the selection of development platform and database is introduced, and the function and application of the whole project management are presented intuitively through the final example effect demonstration.
