基于自适应构件的工作流流程动态变更模型

Dynamic changing model of workflow process based on adaptive component

为了动态适应不断改变的业务环境,对企业业务流程的重组和再造提供支持,使用上下文感知技术,提出了自适应构件。该类构件采用事件机制,动态感知外界环境所发生的变化,并主动调整自身,以适应外部的变化。基于自适应构件,结合柔性工作流机制,构造了一个工作流流程动态变更模型;形式化地描述了模型中流程构件的加入、删除、替换和更新操作,并给出利用四种操作实现流程动态变更的算法。通过实例说明了流程动态变更模型的应用。

In order to adapt to changing business environment dynamically and support restructuring and reengineering of business process,adaptive component was proposed.The new component used the technology of context awareness,it perceived external changes then adjusted itself to adapt to external environment by using event mechanism.With the combination of flexible workflow and the adaptive component as basis,a dynamic changing model of workflow process was constructed.Operations of components in the model such as add,delete,replace and update were formally described.Algorithm to realize process dynamic changing operations was also provided.Finally,an example was used to describe the application of the dynamic changing model.
