一个基于自适应规则库的柔性工作流模型

在传统工作流建模思想的基础上，通过综合考虑各种动态的需求以及流程中的可变因素，提出了一个基于自适应规则库的柔性工作流模型，并从形式化定义的角度出发，详细论述了规则库的设计及应用逻辑。在系统建模阶段尽可能对动态因素进行描述和定义，力求做到定义时的柔性，并允许工作流在执行时进行过程、角色、状态和异常定义的修改，力求做到运行时的适应性柔性，使工作流系统在建模定义的整体框架内可以动态地进行调整，从而实现工作流的动态性和自适应性。

Model of flexible workflow based on adaptive rule database

By thinking about all kinds of dynamic requirements and the alterable factors synthetically and with the traditional ideas of workflow modeling, a model of flexible workflow is put forward based on adaptive rule database. The logic of designing and application is discussed from the point of formalization. And it is tried to describe and define the dynamic factors in the phase of system modeling so as to realize the flexible defining. Further more it is admited to modify the process definition, role definition, status definition and the exception definition in the phase of working so as to realize the adaptive flexibility. The workflow system can be made to adjust dyna- mically in the frame of definition so as to realize the dynamic characteristic and the adaptation.
