协同虚拟样机的工作流管理能支持和控制分布异地的多个集成化产品开发团队的动态协同设计过程,实现对虚拟样机协同设计过程的有效管理,对改善虚拟样机工作效率、提高工作质量起着重要的作用.重点对虚拟样机的工作流时间管理进行了研究,通过对路由结构的分析,采取工作流松弛时间分配方法,调整部分弱不满足时间约束至可满足状态,使更多的工作流实例满足截止期限,降低了异常触发频率,节省了处理开销,提高了运行效率.%Workflow management of collaborative virtual prototype supports and controls the dynamic and collaborative process of designs by many integrated product-developing teams distributed here and there, thus to achieve effective management of the collaborative design process, which plays an important role in improving work efficiency and quality of the virtual prototype. This paper mainly studies the workflow time management of the virtual prototype. By analyzing the routing structures, adopting workflow relaxation time distribution method, and adjusting some weak and demanding time constraints to their satisfactory state, more workflow instances can be enabled to meet deadlines, thus reducing the abnormal triggering frequency, saving the processing cost, and improving operation efficiency.
