摘要
首先介绍了工作流异常处理的体系结构,然后详细介绍了异常处理在流程建模中的描述方式和异常处理的四个基本方法:事务特性与程序设计结合法、知识库法、ECA规则法和工作流进化法。最后展望了工作流异常处理的未来发展方向。
In this paper, we first present exception handling architecture, then introduce the presentation of exception han- dling in workflow modeling and four implementing methods: transaction characteristic integrated with programming, knowledgebased approach, ECA rules approach and the improvement of workflow. Finally, we present a summary and discussthe future research on this area.
