信息系统结构复杂性与可扩展性关系

The Relation Between Expansible and Complexity of Information System Structure

目的研究信息系统结构复杂性与可扩展性之间的内在联系．方法利用基于信息系统的Ｐｅｔｒｉ网模型，并借助于网论中的数学工具，定量地分析了结构复杂性对网络结点耦合特性的影响．结果分析结果表明，要想获得一个结构上相对稳定、又具有一定应变能力的信息系统，其首要的目标是从设计上降低其结构的复杂性，尤其要考虑的是降低其关联复杂度．

Aim To study the relationship between expansible and complexity of information systems structure. Methods The structural complexity influence on the nets nodes characteristic was analysed based on the Petri nets model of information systems and by the math tools in nets theory. Results The analysis results enunciate that if we want to capture a information system which has the power of expansion and the stable structure, it is necessary to cut down the complexity of structure and particularly, to cut down the complexity of relationship. Conclusion This analysis result may be used to analyse the performances of information systems.
