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。
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）.
