We propose the process model of web MIS based on MVC architecture
which can be used to describe the relationship and consequence of data transfer in different layers of MVC architecture.We also give the Petri net modeling steps of web MIS based on MVC architecture
which provides theoretical basis for analyzing
verifying and optimizing the business process of web MIS.Furthermore
we discuss the application of Petri net in system model-ing
taking scientific research MIS of Jinggangshan University as an example.The experiment and the analysis show that the Petri net modeling is feasible and effective on scientific research MIS.
