A Flexible Workflow Model Supporting Dynamic Selection
Abstract
To improve the flexibility of workflow systems, efforts need to be made in the process of workflow modeling and system design. One of the enhancements would be the support of dynamic selection. In this paper, a workflow model based on the extended time interval Petri net with fired mark is presented, which satisfies the requirement of the dynamic treatment of workflows at the execution phase. A three-phase strategy and special node types are used to support dynamic selection, and the discussion about how they could improve the flexibility of the workflow systems is also given. Finally, a prototype system is presented to illustrate the effectiveness of the proposed model.
