| Abstract: | A reflective workflow model based on software architecture is proposed to solve the macroscopical constraint problems in dynamic workflow system. Due to the separation between the abstract software architecture and the physical software architecture on the meta-layer, the realization technology is separated from the applied semantics. By the model, the MAP-metaobject establishes the causal link from the abstract software architecture to the workflow task structure. The ACT-metaobject executes the functions of the workflow instance, such as dispatching activity and inquiring state etc. At last, the dynamic characteristics of workflow from the points of view of activity and process levels are surveyed. |
