运维系统工作流引擎的设计与实现

在工作流管理联盟给出的工作流参考模型中,工作流引擎是参考模型的核心,是任务调度器和资源分配器。文中将FSM(有限状态机)的理念应用于引擎,设计了一个工作流引擎,详细描述了工作流参考模型、有限状态机模型、引擎的调度以及3层B/S模式。最后,采用 J2EE 技术对工作流引擎进行了实现,并成功地将工作流引擎在某企业运维系统中加以应用,取得了良好的效果。

Design and Implementation of Workflow Engine Operation and Maintenance System

In the workflow reference model of workflow management coalition （WfMC） , the workflow engine is the core of the reference model as both the task scheduler and the resource allocator. This paper applies the concept of FSM （ finite state machine） in the design of the workflow engine. The workflow reference model, finite state machine model, engine scheduling and three layer B/S mode are described in detail. Finally the workflow engine is achieved by J2EE technology. The workflow engine is successful applied in the operation and maintenance system of an enterprise with good results.
