摘要
工作流管理的问题由于广泛存在于计算机应用的许多方面而迅速得到发展。本文介绍了一个以扩展的Petri网作为建模工具、以消息队列作为执行机制实现的过程管理的原型系统。该模型描述了活动的并发执行和依赖关系、活动激发的条件、事件顺序及文档管理等信息。执行该模型,在分布、异构、自治的环境中可自动监视、管理和调度工作任务,为业务过程重组、业务过程自动化提供了有力的支持。
Workflow managements have become a rapidly developing technology which involves many disciplines in computer applications.In this paper, a process management prototype is introduced which is modeled with extended Petri - net theory and enacted on the message queue midware Microsoft MSMQ.The description of the process model consists of the concurrent and dependent relationships of activities、activity firing conditions、 event sequences and document management. And the enactment of the process model not only would provide the ability of monitoring 、managing and scheduling business tasks but also give a powerful support for Business Process Reengineering(BPR)and business process automation.
