However, most of workflow products and research prototypes provide the few supports for the verification of XML-based workflow model, such as free-deadlock properties, which is essential to successful application of workflow technology. In this paper, we tackle this problem by mapping the XML-based workflow model into Petri-net, a kind of well-known formalism for modeling, analyzing and verifying system. As a result, the XML-based workflow model can be automatically verified with the help of general Petri-net tools, such as DANAMICS. The presented approach not only enables end users to represent workflow model with XML-based modeling language, but also the correctness of model can be ensured, thus satisfying the needs of business processes.展开更多
工作流系统成功的关键在于向其输入的工作流的质量,因此工作流的建模就显得非常重要。工作流网(WF-net)是由 Petri 网发展起来的一种适用于多种系统的图形化、数学化建模工具。首先它有精确的定义,其次这种形式化体系可以用来反思过程,...工作流系统成功的关键在于向其输入的工作流的质量,因此工作流的建模就显得非常重要。工作流网(WF-net)是由 Petri 网发展起来的一种适用于多种系统的图形化、数学化建模工具。首先它有精确的定义,其次这种形式化体系可以用来反思过程,所以它是一种严格的过程形式化体系。讨论 WF-net 的建模技术,并以办公自动化系统中收文为例说明其应用,并分析其在众多的建模工具中所具有的优势。展开更多
