【摘要】 引入活动多实例使得工作流的处理更加灵活,但引发了同步调度和数据共享冲突等问题。该文给出工作流活动多实例的灵活定义和分类,提出基于"分组-分类"的工作流活动多实例调度机制,将活动多实例分组启动、在同组中分类同步,以解决工作流执行中活动多实例的同步调度问题。该机制无须扩展标准工作流模型,具备一定的工作流语言表达能力。更多还原

【Abstract】 Supporting multiple instances of one activity can make workflow management flexible on handling process, but it causes some problems, such as synchronization schedule and data sharing confliction. This paper proposes a scheme of "group-categorization", which is based on flexible defining workflow activity. And its algorithm is presented. This scheme can not only offer a solution to synchronization schedule of multiple instances of one activity, but also be based on standard workflow model of Workflow Management Coalition(WfMC).更多还原
