摘　　要：为了实现工作流中多实例模式的创建和运行控制,从网络划分的角度提出了一种解决方案。以中国专利201010114083.9中提出的RTWD网工作流模型为基础,讨论了该方案实现方法。在该方法中,包含多实例的子工作流程首先被划分成一个子网,然后基于子网进行多实例的参数定义和运行控制。基于该方法讨论了串行、同步并行、异步并行等多实例模式的运行控制。由于划分出的子网与工作流模型定义保持一致,因而可用原工作流引擎进行调度,简化了多实例工作流模式的实现。To realize the building and controlling of workflow patterns involving multiple instances,a solution was proposed from the perspective of network partition.The implementing method was discussed based on RTWD net proposed by HU Fei-hu,et al.in Patent China 201010114083.9.First,the sub-workflows involving multiple instances should be divided into a subnet.Then the related parameters of multiple instances were defined,and multiple instances were controlled based on it.The paper discussed the controlling of sequential,synchronous and asynchronous parallel workflow patterns involving multiple instances based on the method.Because the divided subnet keeps consistent with the definition of workflow model,multiple instances can be scheduled by original workflow engine,which simplifies the realization of multiple instance patterns.
