基于扩展染色Petri网的工作流过程模型

尽管已有广泛领域应用,但工作流系统在处理业务流程不确定的和动态的参数规格表时存在局限性。为此,本文提出基于扩展染色petri网的CPWF-net以及定义变迁行为和原子过程作为CPWF-net工作流模式结构的支持。这些工作流模式是从微观上进行处理,并可应用于动态不稳定的与时间和数据相关的环境中。本文通过CPWF-net执行程序检测工作流错误或异常执行状态,评估动态业务流程的整体执行时间,证实所提方法的有效性。

A Workflow Process Model Base on Extended Colored Petri-net

Despite their wide range of applications,workflow systems have limitations to deal with the the uncertain and dynamic characteristics of business process.We define CPWF-net based on Extended colored Petri nets for the workflow Modeling of business process and define transition behaviors and function primitives to support the construction of workflow patterns for CPWF-net.These workflow patterns can be microscopically handled and can be adapted for the dynamic and uncertain environment related to data and time.Finally,the method is validated that we can check errors or abnormal executions of workflow and can evaluate the lead time of business process through our program for the CPWF-net.
