A Management System of User Information on a Large Campus Network SUN Huan-dong, ZHAO Dong-sheng, HUANG Jun 2000, (2):  16-20.  Abstract ( 2216 )   PDF (503KB) ( 1487 )   Save As a large campus network connected to Internet, it uses MS Proxy2.0 and MS Exchange5.5 to provide Internet access and email service. Under the situations such as AMMSNet, it is a problem for a lot of ISPs and enterprise/campus network administrators how to maintain and manage the users’ information, how the information of Internet access is monitored, recorded and stored for accounting and testifying, and how the users on the network are administrated automatically. This paper describes a monitoring and managing system programmed in + Builder and MS SQL which implements user management automation in a large campus network.

Information System Modeling Based on Petri Nets WANG Jing-guang, GAN Ren-chu 2000, (2):  21-28.  Abstract ( 2103 )   PDF (972KB) ( 3088 )   Save Traditionally function-oriented modeling and object-oriented modeling are the two major modeing techniques The major advantages of them are the implement of system function, but the abilities to analyze and evaluate in it are too weak. The modeling technology based on Petri Nets advanced in this paper is a good simulation to the system realizing, it could describe the system structure not only, and can be used to analyze the various characteristics of information system by the tools of figuring and mathematics in GNT.

Using of Genetic Algorithms in Stock Control with Fuzzy Logic YU Shu-wei, ZHANG Hua-yu, YANG Lin 2000, (2):  34-40.  Abstract ( 2221 )   PDF (779KB) ( 1819 )   Save In this paper, based on the model of stock control with fuzzy logic, we introduce a new method through which fuzzy contol rules can be got and evaluated with Genetic Algorithms. We name the method as Studying Algorithms of fuzzy rules by two steps. Through the method, the fuzzy control rules can be got and evaluated automatically. With an example, we discuss the usage of this method in stock control and other questions. References | Related Articles | Metrics

The Optimal Urbanization Ratio of China WANG Zheng, WANG Lu 2000, (2):  57-65.  Abstract ( 2019 )   PDF (1308KB) ( 2108 )   Save Urbanization is an essential demand of China’s economic development. When economy reaches a stage at which the gap between rural and urban regions is eliminated, social equality is realized and the surplus agricultural laborers are absorbed without the agricultural production falling down, we say the urbanization of China is on an optimal level. The ratio is the optimal urbanization ratio, which is about 63%. More important, we consider that the key point of the economic growth in the next stage of China is to speed up the urbanization and reach the optimal urbanization ratio.
