摘　　要：在大规模复杂应用环境中,一个业务流程可能涉及企业内或跨地域许多企业内不同的WebService.为了有效支持这类业务流程的处理,提出了一种基于Web Service的可伸缩的工作流管理系统e-ScopeWork的体系结构,研究了其中各组件的功能,详细分析了工作流中任务调度的特点,给出了任务调度、任务管理器处理逻辑以及实现机制,并讨论了流程中任务管理器的部署策略.实现了按应用规模、需求,灵活部署工作流的目标.In the large-scale business environment, a business process may involve lots of different web services arising from one or several enterprises. To handle those business processes efficiently, the architecture of a flexible work flow management system, i.e., e_ ScopeWork is proposed on the basis of web service. The functions of its components are studied to analyze the features of task scheduling in workflow. As a result, the scheduling approach, deployment, and implementation mechanism of tasks or task managers are discussed in detail, thus attaining the goal that a work flow can be deployed flexibly according to the requirements and scale of a business process.
