关于工作流例外处理方法的讨论

Discussion on Approaches to Handle Exceptions in Workflows

现在大多数工作流管理系统可以很好地运行完全可预见的、重复的业务流程。但是,在很多情况下一个业务流程在执行过程中会面 临需要处理可能发生的例外情况。因此,在一个WFMS(工作流管理系统)中必须考虑如何处理各种各样的例外的方法。文章主要分析了可能 影响一个工作流执行的各种例外的特点,并且提出了相应的解决方法。

Workflow technology can be fully exploited when predictable and repetitive processes are executed. Unfortunately, many processes are faced with the need of managing exceptional situations that may arise during their execution,and possibly even more exceptions can occur when the process execution is supported by a WFMS. This paper analyzes the characteristics of the different types of exceptions that may affect the execution of a workflow, and presensts some approaches to their handling.
