摘　　要：工作流管理系统为企业中不同部门之间的协作以及不同应用之间的集成提供了一个功能强大的计算环境 .在当前工作流技术的研究领域中 ,分布式工作流系统逐渐成为研究的热点 ,而系统的可扩展性和柔性是分布式工作流系统成功实施的两个重要因素 .本文介绍了相关的领域概念、系统结构、过程实例的执行以及全局控制机制 ,提出了一种基于企业功能领域划分的、具有高度可扩展性和柔性的分布式工作流系统的设计和实施方案 .Workflow management system (WfMS) has been used to provide a powerful computation environment for integration of different applications and cooperation of different organizations within enterprise. In the current research field of workflow technologies, the distributed workflow engines have gradually caught more and more attentions, and the scalability and flexibility of the whole system are the two critical factors to successful implementation of the distributed workflow system. In this paper, a distributed workflow system with high scalability and high flexibility that runs on different enterprise function domains is introduced. Meanwhile, relevant concept of domain, system infrastructure, implementation of a process instance, and global control mechanism are also presented.
