摘　　要：为有效地处理工作流运行中出现的时间异常,分析了工作流系统对时间异常处理的需求,给出了工作流时间异常处理和工作流时序约束相关活动的定义,提出了时间异常的分类方法和时间异常传播的计算方法,并在此基础上提出了一套行之有效的时间异常处理方法。该方法能够预测由活动延迟异常引起的其他类型的时间异常,并在这些异常实际发生之前对其进行处理。该项研究成果已在产品创新设计领域的工作流系统中得到了验证,并且针对领域特点给出了该领域内时间异常处理方法的具体操作和算法。To handle the time exception in workflow operation, the requirements of time exception handling in work- flow operations were analyzed. Time exception handling and interrelated activities of time constraint in workflow were defined. Also classification method for time exception handling in workflow and an algorithm of time exception spread were presented. Then, a feasible method for time exception handling in workflow was proposed. This method could predict the potential time exception arose from the activity delay exception and handle them before they actually took place. The method was implemented and validated through a real workflow management system. In this system, some operation steps and algorithm of the method aiming to this special field were provided.
