针对企业大量业务流程经常变化的特点和管理问题,提出一种基于XML的项目管理工作流模型.对工作流管理联盟制定的工作流过程定义元模型进行了改进和简化,并给出了元模型的组成元素与相关属性;基于改进的工作流元模型,使用XML对工作流过程模型进行了定义;介绍了工作流引擎的主要设计思想和DOM4J解析方法.基于过站航班运行保障流程建模实验结果表明,所提出的基于XML的工作流模型能很好地表示任务节点及其关系,并且便于数据的传输和共享.%According to the characteristics of a large enterprise business processes constantly change and management problems,a project management workflow model based on XML is proposed.The workflow process definition meta model made by the workflow management coalition was improved and simplified firstly,and the elements and related attributes were given.Then based on the improved workflow process meta model,the workflow process model was defined in XML.Finally,the main design idea of the workflow engine and the DOM4J parse step were introduced.Based on the experimental result of the over station flight operation support process modeling,it is show that the workflow model based on XML can well represent the task nodes and their relationships,and is convenient for data transmission and sharing.
