Research On Modeling Method Of Business Process Based On Object-Oriented Colored Petri Nrt

Economic globalization and the continuous development of information technology, not only change the enterprise management, also brought unprecedented severe competition. Enterprise informationization has become an important safeguard for modern companies to enhance competitiveness and an important condition to respond to global economic integration. More and more companies begin to implement information strategies to improve their operational efficiency and overall competitiveness, and management informationization is the important content of the enterprises informatization. In the process of enterprise informationization projects, people gradually realize the importance of business process in the informationization projects, and business process reengineering is the effective means to complete the change of enterprise management model and organization. As a high-cost, high-risk complex systems engineering, BPR implementation must be guided by the system scientific methodology be successful, and exploring practical business process modeling method to implement BPR is particularly important.This paper summarizes the research status, through analysis and comparison of different modeling methods, chose Petri nets as the basic modeling tools. In order to solve the problem of complexity raised by the classic Petri net modeling in modeling of complex system and the feature that business contacts between economic entities in manufacturing enterprise are usually along with material flow, information flow and etc, this paper proposed three-color Petri net which is three color-coded by entity, information and uniform. However, since the three-color Petri net is non-modular design and lack of reusability, it could not solve radically the problem of modeling complexity. Therefore, this article will draw object-oriented technology into Petri net systems, proposed a kind of extended object-oriented colored Petri net (OOCPN). This article also gives a method based on hierarchical thinking to verify the correctness of the model. Finally, through a case study to discuss and test the modeling method proposed in this paper.OOCPN modeling not only decomposes complex systems using object-oriented technology, reducing the difficulty of information system modeling effectively, enhancing features such as modularization, but also can describe clearly the business process of complex system with the help of three-color Petri net's graphical tool, and could do descriptive to systems correctly as well.
