摘要
Petri网是一种有效的模型描述语言,不仅能描述系统的结构特性,同时还能描述其动态特性,尤其适用于描述含有并行成分的系统。本文在简要介绍了Petri网和工作流基本模式的基础上,利用替换规则用基本工作流模式构造了合理的Petri网模型,并对构造好的Petri网模型进行详细的分析,同时在分析的基础上提出了对应的优化方案。最后对基于Petri网的工作流模型进行了总结。
Petri net is an effective description language for model. It not only can describe the structure characteristic of the system, but also can describe the dynamic characteristic, and especially can describe the system including parallel components. This paper introduces the basic model Petri and workflow, and use of replacement rules of the basic workflow model with a reasonable structure Petri net model, and a good structure for a detailed analysis of Petri net model, based on the analysis of the optimization program. Finally, the model is based on Petri summed up the workflow.
