摘要
迁移工作流是迁移实例借助工作位置服务就地执行任务的移动计算模式,如何保证工作位置为迁移实例提供可靠的工作流服务,是迁移工作流管理系统设计中必须解决的一个关键问题。提出了一种基于案例推理的工作流服务方法,它利用服务案例支持迁移实例的正常工作,利用异常案例支持任务的异常处理。实验用例表明,该方法可以大大增强系统处理工作流服务异常的能力。
Migrating workflow is a mobile computing model in which the migrating instance executes tasks locally by making use of the work place services. How to ensure the liable workflow services provided by work place for the migrating instance is a key problem, which must be encountered in the design of the migrating workflow system. The paper proposed a workflow service method based on the case reasoning, which utilized service cases to keep the migrating instance working correctly and exception cases to support the tasks＇ exception handling. Experimental case shows the method can strengthen the system＇s ability to handle the workflow service exceptions.
