提出了一种事件驱动的工作流管理系统设计.该设计基于ICE通信中间件实现,工作流控制引擎解析建模工具定义好的工作流过程模型,将模型信息保存在关系数据库中,然后将过程模型中定义的活动分配到分布式的执行引擎中执行.执行引擎通过检测事件来判断分派到其上的活动是否应该启动.文中所设计实现的工作流管理系统,不仅可以与其它工作流管理系统共享过程定义,而且很好地解决了传统软件开发中存在的编程语言单一、部署集中的问题,明显提高了系统的可扩展性、柔韧性和处理复杂业务流程的能力.%A event-driven design for workflow management is presented in this paper. The implementation is based on ICE. The process model can be analyzed and saved in relation database by control engine. Activities defined in workflow process model are assigned to distributed execution engine to execute. Events are used to determine the execution of activities on execution engine. It could share procedure definitions with other workflow managements. Additionally, it could solve the problems like singleness programming language and amassed deployment. The expandability and the flexibility of the system is impoved obviously.
