基于WEB的柔性工作流引擎的设计

作流引擎是工作流管理系统的核心,为了使工作流管理系统具有动态适应能力,提出了一种基于Web的柔性工作流引擎的设计方法—支持工作流引擎对流程的动态修改。首先分析了工作流引擎的功能结构及体系结构;其次,结合工作流引擎数据模型的ER图,阐述了柔性工作流引擎的数据模型及控制模型的设计方法,并重点介绍了控制模型中的路由控制与状态转换的实现机制;最后,给出了柔性工作流引擎的动态适应策略。

Design of Flexible Workflow Engine based on Web

Workflow engine is the core of workflow management system. to make workflow management system has dynamic adaptivecapacity , a design method of flexible workflow engine based on Web which supports workflow dynamic modification in process is putforward. Firstly, function structure and system structure of the workflow engine is analyzed; Secondly, according to the data model ERchart of workflow engine ,designing methods of the data model and controlling model of the flexible workflow engine are explained,and the realization mechanism of the route controlling and state transition in controlling model especially; At last, the flexible work-flow engine dynamic adaptation tactics is explained.
