Abstract: 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.

Key words: workflow, context awareness, adaptive component, process dynamic changing, models
