基于P/T系统化简方法的工作流过程模型验证

目前工作流技术在管理、生产和科学研究等领域中已经被广泛应用.由于过程逻辑的复杂性和变化性等原因,如何建立良构的业务过程是一个比较现实的问题.因此,对过程模型进行分析和优化成为工作流技术的研究方向之一.首先,根据改进的工作流过程元模型,研究并提出了一种基于P/T系统的工作流过程模型过程网.基于过程网给出了一组化简规则,用于验证过程模型中的死锁和乏同步两种结构冲突.最后,结合一个业务过程实例,根据转换规则把它映射为过程网,应用规则进行化简并得到验证结果.

Workflow Process Model Verification Using Reduction Method Based on P/T System

Nowadays, workflow technology has been intensively applied in the domains of administration, production, and scientific research. For the complexity and variability of process logic, how to build a well-structured business process is a practical problem. Thus, process model analysis and improvement become one of research directions in workflow technology. Firstly, according to the modified workflow process meta-model, a P/T system based workflow model procedure net is proposed. And then, a set of simplification rules are given to verify two structural conflicts of the process model, i.e. deadlock and lack of synchronization. Finally, following these rules, a procedure net example transformed from a business process is simplified, and the result is obtained.
