Research of dynamic workflow supporting multiple instances pattern
支持多实例模式的动态工作流研究

To express dynamic semantic of multiple instances pattern of workflow, a XPDL-based modeling approach was presented through analyzing the pattern. Meanwhile, the design of corresponsive component in workflow engine was given, and it was implemented in an open source workflow engine: Enhydra Shark. In this component, the design of "Activity Instances Manager" solved the dynamic execution and data sharing problem of instances. Running of the engine proves that this solution can support the multiple instances pattern efficiently, and improve the dynamic of workflow model.
