To analyze the characteristics of key data in business process and the interaction between them,a variant of high-level Petri net-XAr/T-net was proposed by describing the structure and operation of Artifact with eXtensible Markup Language (XML),and the Artifact-centered business process was also modeled.The research result showed that XAr/T-net model not only could analyze the uniqueness,accessibility and persistence of Artifact in each independent business process,but also express the interaction between different types Artifact was expressed in business process.%为分析业务流程中关键数据的特性及数据之间的交互关系,用可扩展标记语言形式描述业务流程中的数据实体Artifact的结构及其操作,提出一种高级Petri网的变体XAr/T-net,对以Artifact为中心的业务流程进行建模.研究结果表明,XAr/T-net模型既可以分析各个独立的业务子流程中Artifact的唯一性、可达性和持久性,又可以表达业务流程中各类型Artifact之间的交互.
