摘　　要：提出了用UML活动图描述工作流异常处理的方法。根据工作流系统特点,对UML活动图作适当扩展,为扩展后的活动图定义了的形式化语句,通过实现一个RCT步来描述一个潜在发生的异常状况,并对不同处理策略下的处理过程进行了描述。结果使得UML活动图适合描述含有异常的工作流系统;由于是采用了UML建模语言,编码实现更容易。The approach to present the exception handing with activity diagram is put forward in workflow system. According to the characteristic of the workflow system, a formal semantic of extending UML activity diagram is defined. Through the transferred condition to implement a RCT step, a potential exception is presented, and the handling procedures are described under different strategies. As a result, UML activity diagram fits preferably for presentation of exception handing in workflow system, and the coding of workflow system is implement easily because of the UML modeling language.
