Researches On Modelling Of Workflow Based On The UML

Workflow technology is the research hotspot in computer application domain. Enterprisebusiness process modeling and analysis in-depth with Workflow technology can normalizeEnterprise business process, find the irrational and inefficient section, then optimize and regroupthe business process, improve the efficiency roundly. And enterprise business process model isalso the important repository and regulations which can instruct enterprise to implementcomputer informational management model. Therefore, studying deeply and advancingenergetically Workflow Technology have a important realistic significance which can promotenormalization and informatization of enterprise management, then improve economiceffectiveness.UML is a kind of language, which is well defined, easily to express, powerful and can becommonly used. It has the new method and new technique of the software engineering. It adoptsa suit of mature modeling technique. It can be used to describe the machine system, enterpriseframework and business system as well as set up the commonly used software system modeling.It can also build the modeling of any kind system, which has the static state structure or dynamicstate action.Workflow modeling technology is one of the core problems in the area of Workflowtechnology. Researchers have given us a lot of valuable methods. This paper analyses thetraditional Workflow modeling methods, points out the drop and lack of them and analyze themodeling ability of the UML. Analyses and researches of modeling the Workflow with UML aredone based on analyzing functions of WfMS and the ability of UML. At last, brings forward akind of Workflow modeling method based on extended UML Activity diagram. The major research works and initiative points in this thesis are as follows:1.Researching the methods of current Workflow modelling, analyzing the deficiency thatexists and carrying on analysis to the ability of UML activity modelling diagram;2.Giving detailed analysis and research in using UML to make the Workflow model, givingthe flow of Workflow modelling and showing the basic modelling method with UML from fouraspects, they are using case view, activity view, state machine view and interactive view. At lastgiving the specific analysis;3.Bringing forward a method of Workflow modeling based on the UML Activity diagram,dividing the main content involved in the process modeling into three species, they are controlinformation, touching off information and activity, extending them and giving the advantages ofthis method.4.Defining the modeling elements, routing structure, modeling rule and executing rule ofthe new Workflow modeling method in non-formalized and formalized method.Lastly, give a summary of this paper, point out the shortcoming and preview the followingjob.The extended of the UML activity diagram enriches the variety of the operation element inthe activity diagram, increases the data stream and the structured analysis of the Workflow model,and adds the expression manner. It can depict the whole operation process from the basic point ofview. Besides of this, it not only can depict the operation information of the process distinctly, butalso can make the system look less numerous and complicated.
