摘要
针对目前工作流任务分配考虑的因素比较单调,灵活性较差.为了解决工作流引擎任务动态分配的用户最优选择问题.本文引入Active XML(分布式数据管理语言)作为工作流模型定义语言,来创建能够动态修改的工作流模型.设计并实现一个动态自适应工作流引擎,该引擎在工作流执行过程中能够根据参与者的状态和负载运行状况,通过WTAM任务分配算法,将任务动态分配给负载较低、经验值较高的用户,缩短工作流执行时间,提高工作流的运行效率.
In view of that the present workflow task allocation factor is monotonous and of poor flexibility, the active XML（ distributed data management language） was introduced as a workflow model definition language to create a workflow model supporting dynamic modification in order to solve the user optimal selection problem of the dynamic allocation of the world＇low engine task. A dynamic and adaptive workflow engine was designed and implemented, which can dynamically allocate the task to the user with lower load and higher experience value according to the state and load of the participants during the execution of the workflow by using the WTAM task alloca- tion algorithm, shortening the execution time of the action flow and improving the running efficiency of the workflow.
