The Design And Implementation Of Workflow Designer Which Is Based On RCP And Support Dynamic Expansion

Current as an enterprise process modeling and process management core technology workflow management technology is used to make up for the deficiency of traditional enterprise information system and to improve the working efficiency and quality of service for enterprises. In the process of practice to optimize business process model, realize the business process reengineering, combine the existing business has already become the key of enterprise information system construction.With a management system project as the background in this paper, a graphical user interface design and modification of visualization is achieved , the custom control and custom control properties is extended, the expression of interface is riched, with Web workflow interface, the information, standardization and integration of process definition, preparation, initiate, implement and monitoring is realized. Using the project management system has many features: cycle is short; based on mature products, stable performance; visual environment, easy to operate; open architecture, easy maintenance.This paper firstly establishes this topic research background and significance, and analyses the development status of the workflow technology and RCP at home and abroad, and discusses the relevant core technology in the system, and chooses the most suitable techniques. Then further analysis the workflow designer module that this paper is mainly studied at, improve the workflow model, workflow mode and operation mode of workflow engine. On this basis, the paper design and implement of the dynamic adjustment workflow engine based on GERT net, by redesign or modify the process definition in the light of actual conditions to monitoring and management the workflow at real time. Then the paper describes using EMF and GEF technology to construct process definition tool, compares with the basic component needs in workflow management system, designs the system structure and technical architecture, and introduces custom form, business module, the workflow engine, process definition tools, process management and monitoring, the client process that is composed in workflow designer and the step in modeling process, finally summaries and put forward the prospects of this paper.
