Research And Realization Of A Workflow Management System Based On WEB

With the business requirements changing constantly, the design, optimization and management of business process become important means of enterprise competition. Now, workflow technology has become the core technology for the definition, management and control of process, and Workflow Management System (WfMS) is based on workflow technology. By transferring reasonably and distributing concerned information and resource to correspond each activity in business procedure, it can help to realize business object of enterprise efficiently and to reforge business procedures better. However, as the rapid development in the electronic commerce in the internet, the traditional management system of the work flow cannot adapt to that of the request of modern enterprise. Mainly for the system can't adapt to the business handling processes of the enterprise which are getting more and more complex, and lacks flexibility and the interoperability, therefore cannot support the work flow which keeps dynamically changing and trans-organizations.Workflow Foundation is an enterprise work class development frame and the engine, has provided a programming frame and the tool develops and carries out each kind differently based on the work class application procedure. It allows a work class to define as a series of activities, and has provided when the movement the foundation, the nimble work class control mechanism, the long time movement and the condition work class, when time the movement and the design transparency speaking of the user, as well as uses in the rule deference and records management process verification ability, a possessor participates in (Human), the system (System), continual (Sequential) and the state machine (State-Machine) the work class.Aiming at the disadvantages of the traditional work flow management system, based on deep study of Workflow Foundation, a system is to be set up for workflow application in this pape,and give out a common workflow management system structure which is useful when you want to apply workflow technology to enterprise application.On its hierarchical structure N layer truss is used with the natures of excellent trans-platform and systematical toughness; On the workflow model, it is proposed to adopt organization model, resources model, data model and active model which can effectively adapt to the large-scale enterprise service flow. On the flow designing, a work flow constructing method is proposed to use based on the drive of the activities. And it is discussed about how various functions modules of the system cooperate in detail. At last, an application example is give to illustrate the issues.
