Based On The Shark's Dynamic Workflow Model Applications

Along with the competition between enterprises getting more and more intense,, Workflow technology has currently become one of the important research directions. Meanwhile, research on the Workflow engine which is the core of the workflow has been focused on. Since the open-source Shark workflow engine (Version 1.0) has been developed in September 2004, multitudinous project developers and researchers have been attracted. Now management system which is based on the Shark workflow has been widely applied.According to the reference model of the workflow management system, this paper has incisively analyzed and studied the system structure, main classes and packages of the workflow engine. Considering common OA retrieval / rollback dynamic workflow pattern, methods and processing strategies based on the Shark retrieval / rollback pattern have been presented to support the operation of the dynamic retrieval / rollback, which ensures the correct distribution of the task and the consistency of the state and data when workflow is operated. As the re-development to the Shark has been carried on, retrieval / rollback function has been realized and applied to the bank OA system project.Practice has proved that as the new method of the dynamic workflow has been applied in the OA system, dynamic retrieval / rollback of the documents has been realized; furthermore, the flexibility and dynamic handling capacity of the Workflow Management System has been enhanced. Thus the OA system can be more ready to cope with the uncertainty and variability of modern business process, thereby to improve the efficiency and lower the operating cost of enterprises. After the project has been developed and put into operation, the desired goals have been achieved. Now the system performs stably.
