摘　　要：通过研究基于开源工作流Enhydra Shark与Jboss JBPM针对工作流动态分配任务的解决方案及其存在的问题,提出利用子流程来解决动态分配任务问题。即由执行人在执行任务过程中动态的开启子流程,提供了很大的灵活性,执行人可以根据业务需求选择合适的流程模板,避免预先定义子流程模板的弊端,很好地满足现代企业复杂多变的业务需求。在跨域应用中明显的体现出其优势,用户可以利用本地的流程模板完成外域的任务。最后,给出子流程的设计与实现方案,并将其应用于文档送审的实际项目中,取得了良好的效果。Through the study of the solutions of Enhydra Shark and Jboss JBPM for the problem of allocating task dynamically in the implementation of the workflow and the deficiencies oftheir solutions. Sub-processes is used to achieve dynamic allocation of tasks to meet the changing needs of customers and complex business logic processing requirements. When executor carried out its task, a suitable sub-processes templates is choosen with more flexibility according to the business needs, avoiding the drawbacks of pre--defined sub-process templates. In distributed workflow applications, executor can choose local workflow process templates to finish foreign domain tasks. Finally, the design of the solution is given and is applied in the documents submitted of the actual projects, good results are obtained.
