中文摘要：

文中提出了基于MVC架构的web型信息管理流程模型，并通过定义的模型五元组来描述各层之间数据传递的关系和结果．给出了基于MVC架构的web型MIS系统Petri网建模基本步骤，为web型MIS系统的业务流程的分析、验证与优化提供了理论依据．以井冈山大学科研管理信息系统为例，讨论了Petri网理论在建模中的应用，实验结果表明采用Petri网理论对科研管理信息系统建模是可行且有效的．

英文摘要：

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.
