摘要
传统的信息系统建模技术主要有如以数据流图 (DFD)为手段的功能建模和以对象图为手段的对象建模 ,它们多强调的是系统功能的实现 ,对系统性能的分析和评价能力则显得过于薄弱。本文提出的一种基于Petri网的信息系统建模技术 ,作为从实际问题到Petri网的桥梁 ,对于系统的实现是一种很好的模拟 ,它可以充分利用网论强大的图形表达能力和严谨的数学分析理论对信息系统的各种综合性能进行描述和分析 ,具有一定应用价值。
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.
