Abstract: Aiming at the local character of migrating workflow exception and architecture of working position, this paper proposes a working position exception processing model based on ECA rule and Case-Based Reasoning(CBR). This model detects the exceptions through the proactive detection and passive detection, handles the exceptions using the ECA rule and the CBR method, realizes working position exception handling by using local exception rule bank. Application results show that this model enhances the ability to handle predictable and unpredictable exception.

摘要： 针对迁移工作流异常的本地特性和工作位置的体系结构，提出一种基于事件-条件-动作(ECA)规则和案例推理(CBR)的工作位置异常处理模型。该模型采取主动检测和异常检测混合的检测技术，利用本地异常规则库实现工作位置异常处理。应用结果表明，该模型增强了不可预测异常、可预测异常的处理能力。
