基于对象模型工作流的失败处理与失败恢复

工作流的失败处理和失败恢复是工作流管理系统的重要组成部分.提出了一种新的基于对象的工作流模型,在此模型下设计了工作流失败处理和失败恢复的策略.与传统方法相比,新策略考虑了工作步骤之间的控制依赖和数据依赖,并且对工作步骤应用的具体实现方式进行了探讨,以提高工作流失败处理和失败恢复的效率.

Failure Handling and Recovery in Workflow Based on Object Model

The failure handling and the failure recovery are the key parts of workflow management. In this paper, a workflow model based on object is introduced. And the strategy of failure handling and failure recovery is given under the proposed workflow model. Compared with the traditional method, the new strategy takes into account both the control dependency and the data dependency between workflow tasks during the failure handling and the failure recovery. What is more, how to implement the workflow task application is explored to improve the efficiency in the failure handling and the failure recovery.
