Workflow Modeling and Application Based on Colored Petri Net

Abstract

Abstract: According to traditional Petri net when describing Workflow model, form element quantity too much , can not embody data flow as well as can not manage the defects such as many instances, according to the analysis method of theory of Colored Petri net ( CPN ), have expanded Workflow-net ( WF-net ) ,the paper puts forward a kind of new development Workflow net CPWF-net ( Workflow-net based on Colored Petri net ) , givs strict definition and enabed mechanism and trigger mechanism, analyses the property of CPWF-net all-sidedly , and carries out preliminary research in the aspect of actual application.

摘要： 对传统Petri网在描述工作流模型时,组成模型的元素数量过多、无法体现数据流以及无法管理多个工作流实例等缺陷,将有色Petri网(Colored Petri net,CPN)理论的分析方法引入到工作流网(Workflow-net,WF-net),实现二者有机结合,提出了一种新型扩展工作流网CPWF-net(Workflow-net based on Colored Petri net),给出了严格的定义、使能机制和触发机制,全面分析了CPWF-net的特性,并就其实际应用进行了初步探究。
