Applied Research Of Workflow Technology In Cyclic Machine Printing Management System

Contemporary corporations are facing variant changes and global competitions. To improve the competence of manufacturing systems, the Workflow Management System (WfMS) has received much attention. As a new technology, the theories of Workflow become to the hot research of IT domain, it has broad application in the way of carry out the recombine and autoimmunization of business process.The printing industry has particular producing and managing way, it's producing process has strict sequence and rule, what's more, it involved many departments. As a result of adopting the produce way of required-print, there are too many data through the producing, traditional manual manage way can't accommodate the printing process. Applying the workflow technology to printing production, not only can enhance the efficiency of production, but can also help enterprises analyze and reengineer business process.This paper's technology background is an actual project of Dalian Boya printing limited company. Combining the workflow technology and cyclic machine production methods, it develops a workflow-based printing management system, by applying the synchronization net model to cyclic machine printing production ERP system.Synchronization net model (Syn_net), a formal workflow model of Petri-net-based and C_net-based, is introduced in this paper, which divides the workflow model to three levels, logic layer, semantic layer and execute layer. Compared to WF_net, the model is easier to be analyzed and simulated. Combined with the business process of cyclic machine printing, this paper discusses the application of the synchronization model, and tests the correctness of the model. And then using the workflow technology and relational database technology, this paper develops a lightweight workflow engine. Recurred to the mature technology of relational database, the workflow engine simplifies the workflow management greatly and optimizes the performance of the system. At last, this paper introduces the cyclic machine printing management, and gives the design and implementation of the system.The system improves the flexibility, control and automatic or semi-automatic by using the workflow technology. The system has been used in Dalian Boya Printing limited company, and the result is very well.
