基于Agent的分布式工作流控制模型研究

Research on distributed workflow control model based on Agent

为了实现虚拟企业的业务过程管理,引入智能体,设计了一种新型工作流控制模型。该模型利用任务执行智能体的信息传递,实现分布式工作流的动态划分;利用评估工作流引擎,实现对工作流中任务前置条件的评价。任务执行智能体所实施的工作流执行与控制算法,分两个阶段评价工作流的依赖,避免了不必要的依赖评价和信息发送,从而有效完成虚拟企业的分布式工作流控制。

To implement business process management in virtual enterprises, a kind of new workflow control model was proposed by introduction of Agent. In this model, message forwarding among task execution agents were used to implement dynamic partitioning of distributed workflow. Evaluation of precondition for tasks in workflow was implemented by evaluating workflow engine. Workflow dependence was evaluated in two stages by the workflow execution ＆ control algorithm at task Agent so as to avoid unnecessary dependence evaluation and information transmission. It could effectively accomplish distributed workflow control for virtual enterprises.
