【摘要】 本文以大连市计划委员会项目管理系统为背景，针对传统项目管理系统对项目的业务流程采用“硬编码”的方式进行管理不能满足现代项目管理业务流程多样化和不确定性需求的问题，提出用工作流和元数据技术来构建“柔性”的项目管理系统。本论文完成的主要工作如下： (1)采用工作流技术把项目的业务流程从传统项目管理系统的应用程序中抽取出来，利用工作流管理子系统单独管理，使用户动态地管理项目业务流程； (2)采用元数据技术动态地定义项目应用数据； (3)在实际系统中，采用Java的模式-视图-控制器(MVC)的模式进行开发，系统的业务逻辑和用户视图进行分离，使系统的开发和维护变得更加容易； (4)针对如何从手工的管理系统平滑的过渡到基于工作流技术的计算机项目管理系统的问题，提出了一套系统的方法——工作流法。 实际系统已投入使用，在大连市计划委员会的固定资产投资一处、固定资产投资二处、能源交通处和高新技术产业处等多个处室使用，目前处理项目近千个，使用效果良好。更多还原

【Abstract】 With the project management system of Dalian Municipal Planning Commission setting, aiming at the problem, the conventional project management system which manages the business process with hard coded method, can’t satisfy the requirement of the diversity and uncertainty of business process in modern project management, the paper describes the flexible project management system constructed by workflow and meta-data technology. The major completed work as follows:(1) In the system, the business process is abstracted from the application of conventional project management system by adopting workflow technology and is separately managed by workflow management sub-system, in this way, the users can dynamically manage the business process according to the actual demand.(2) At the same time, the application data of project, which is disposed by the step of business process, is easy to be defined by adopting meta-data technology.(3) In the course of developing the system, the architecture of model-view-controller is used, which makes the business logic and user view separate. It makes the development and maintenance of system become easier.(4)Besides, aiming at how to transform hand-worked management system to computer management system based on workflow technology, a systemic method ------workflow method is described.The system has been used by department I of fixed assets investment , department II of fixed assets investment ,department of energy sources and communications and department of high-tech industrial in Dalian Municipal Planning Commission and has dealt with almost 1000 projects. The effect sounds good.更多还原
