Petri网在工作流引擎中的应用分析

Analysis of Application of Workflow Engine Based on Petri nets

目前对工作流技术进行深入的研究对于提高企业的信息化程度、运行效率以及竞争能力都有重要的意义,而工作流引擎是整个工作流管理系统的核心。该文首先介绍了工作流引擎的定义和5个重要接口,以及Petri网的概念和建模优势。其次比较了OpenWFE,jBpm,YAWL,Bossa等开源工作流引擎,指出基于Petri网调度算法的工作流引擎所具有的优势。在此基础上重点分析了Bossa引擎的调度算法,最后对Petri网在工作流引擎中的使用提出展望。

At present,depth study of workflow technology is important to improve the level of enterprises,operating efficiency and competitiveness,and the workflow engine is core of the workflow management system.This article first introduced the definition of workflow engine and its five important interface,as well as the concept of Petri nets and modeling advantages.Second,the paper compared OpenWFE,jBpm,YAWL,Bossa,such as open-source workflow engine.,and indicates the advantage of workflow scheduling algorithm based on Petri nets.On the basis Bossa scheduling engine has been the focus of analysis.At last,the article Outlooks application of workflow engine based on Petri nets.
