流程违例处理的行为及分析

业务流程运行期间，外部或运行环境中的某些属性与流程设计时所设定的条件不一致时，将导致流程运行时的违例，违例处理方法涉及流程运行时违例的发现和处理。首先介绍了流程的违例及其分类;基于流程违例处理模式，使用CCS偶图对流程工作项级、案例级违例处理以及相关补偿处理进行分析和表述;在违例处理策略讨论的基础上，总结了违例处理模式的基本形式，并通过CCS偶图的动态特征分析了违例处理的动态行为。

Exception Handling Analysis for Business Process

Exceptions are aroused when built in attributes for executing a well-designed business process are not supported. Process exception handling technology involves detecting and processing runtime exceptions in process executing environment. This paper first introduced features and classification of business process exception. Based on Exception Handling Patterns, bigraphs for CCS were applied to investigating process exception handling, and some results regarding modeling and analysis were discussed. At last, exception handling strategics were applied to analyzing exception handling patterns,and basic model structure and dynamic behavior analysis for process exception handling were proposed in the paper.
