【摘要】 随着工作流管理的发展,人们提出了很多扩展Petri网概念用于工作流建模。描述工作流中的资源、资源条件以及任务与资源条件之间的关系是一件很复杂的事情。而现有的用于描述工作流的Petri网在这方面,并不令人满意。该文特别强调资源的概念,在时间Petri网的基础上提出了一种新Petri网———资源条件/任务网(ResourceCondition/Tasknet,简称RC/TN),利用RC/TN网来进行工作流建模,描述工作流的执行过程。并将该工作流建模方法应用于OA流程的描述中。更多还原

【Abstract】 With the development of workflow management ,many high petri nets(PNs )are developed and used on modeling workflows.Describing workflow resources,resource conditions and relations between tasks and resource conditions is a hard thing.The high PNs used today are weak in this aspect.Especially emphasizing resources,this paper presents a new petri net-- - the Resource Condition/Task net(RC/TN)based on the timed petri net,and uses the RC/TN to model workflows and describe execution of workflows.And this modeling method is used in the OA workflow modeling.更多还原
