The Design And Implementation Of Document Automation Processing System Based On UML And Petri Net

Along with the rapid development of information technology, no matter what the Government,institutions and enterprises, in order to standardize the workflow and improve office efficiency and speed up the pace of information technology, to achieve the management of information technology, scientific, and to enhance the management level, have an urgent need to establish a set of Office Automation System. Office automation is the use of advanced science and technology, continue to make part of the operational activities of the office that materialized in a variety of devices other than by the equipment and office personnel to serve the goals of a human information processing system. The article is based on an enterprise's actual background for the development of OA system of applied research, use Brower/Server model, and at the same time combined with JSP, XML, Servlet, Javascript and other technology to achieve the system. The paper major research is as follows:(1)Through the project to study the work of enterprises and institutions and work flow methods to study the general framework of OA system structure, the completion of the demand for system design analysis and the overall module design(2)Based on UML established use case diagram and state diagram of system, and to discus the rules of mapping from the UML state diagram to Petri nets, as the basis of state diagram build a dynamic model of Petri net for the system.(3)Use Petri nets'place to transition rules to descript sending the document, receiving the document, applying for reimbursement, conferences, common dealing with things, asking for leave six workflow processing.(4)At the same time, three types of workflow patterns are defined in the system, customized for process model, author of the center for process model and transactor for process model, sending the document, receiving the document and applying for reimbursement are customized for process model, conferences and common dealing with things are author of the center for process model, asking for leave is customized for process model, six kinds of work processes are based on the actual needs of the different processes to determine what the workflow process model to use.
