The Overhaul Workflow System Used In Local Railway

As the scope of business in the world expanding, relations between corporations deepening, the workflow management system has been applied abroad in corporations at the beginning of this century. Researches on workflow technology and products development of it have been developed rapidly as well. The Workflow technology is one of the research focuses on the field of CSCW at the beginning of this century, which is related to many subjects such as Computer Science, Management, etc. It is of great importance to research deeply the workflow technology, so as to improve the degree of enterprise information, operation efficiency and competitive ability.In this paper, the workflow management technology based on the application of CSCW is studied, For working out the problem that although many people using the Petri net as their modeling tool, it is difficult to inject the Petri net model into MIS based on the relational database. I proposed a model which inject the Petri net model into relational database. And based on the research on theory and technology mentioned above, a visualized definition tool for supporting the workflow of computer collaborative design is realized, An effective solution is put forward which is mainly used in workflow role definition, exception handle, verification of workflow soundness.Finally, the implementation of workflow system which is actually used in Xiao Liu local railway enterprises is described.
