摘　　要：工作流管理系统在不同的领域得到了广泛应用,但仍然未能满足任务回撤等特殊业务需求。文章首先对任务回撤进行了描述,并简要介绍目前的几种解决策略,然后在研究典型工作流过程元模型的基础上,引入新的模型因子——服务接口（Interface）,提出并建立基于服务过程分解（Service Process Division,SPD）的、具有动态特性的工作流过程模型。最后通过改造开放源代码产品JBPM,在实际中得到应用。Although workflow management system has been used in many different fields,it cannot satisfy with some special business needs,as like task rollback.The business scene of task rollback is first described,and then the current solving strategies are overviewed.Afterwards,based on the research of workflow process meta-model which many workflow products reference to,the factor of interface is introduced and is added into the dynamic model which called based on Service Process Division（SPD） model.Finally,programming on JBPM which is an open source project,this model is applied in practice.
