| In recent years with the development of the technological, in the modern management, the information is more and more important, and the information system which operate it is more and more important. So, choose a proper modeling method for information system is the most important things. Because of the characteristic of Petri nets, it is of very obvious practical significance and high value of application to apply object oriented Petri nets to modeling information system.This paper adopted demonstration analysis and academic analysis to study the modeling business process based on the object oriented Petri nets. Firstly, this paper illustrates the necessary of the research on modeling of business process and the present situation of both domestic and overseas research and background of the research. Then introduced some conception of workflow, at the same time, we compared each of modeling method of management which suits different type of management, make out a intuitionistic analyse table. Secondly, we introduced the classical Petri nets and the development direction of it, it is a foundation of the research of this paper, on the base of it, through the analyse of present situation of both domestic and overseas research and the research on characteristic of business process, we integrate the modularity of object oriented method and the simulate ability of Petri nets and it's religious analyze method, the way of transferring information on internet, finally proposes the modeling method based on improved object oriented Petri nets. In this paper we introduce this modeling method comprehensively and detailedly, introduced from the description of whole structure to formalize definition, to the model procedure and step and the process of run. At the last of this paper, the validity and possibility have been proved by make a case study for an actual business process according to proposed modeling method, it from general analyzing process to detail designing to implement. |
