| 摘 要： | 将点权核度与点权核的概念引入水资源系统。通过对节点根据功能的大小来赋权,以便从功能和结构两方面出发,对系统内各元素的重要性进行测度,从而找出系统的核心工程。并利用该定义,研究了系统的层次结构的确定方法,给出了建立系统层次结构的算法。

| Abstract: | The sketch network,which is often used in water resource system to simplify the studied problems,is seldom used for system analysis.In fact,knowledge related to the sketch network could be used to analysis the system deeply,which is common used in social system and communication system.In this paper, the concepts of the node-weighted core degree and the node-weighted core are introduced into water resource system.According to experts' knowledge,we can weight the elements of the system,that is,the nodes of the sketch network,and then measure the importance of elements of system from the sides of function and structure.Therefore,the core engineering of system can be founded.Based on these concepts,the hierarchical structure of system is studied,and an algorithm calculating the hierarchical structure is given here. |
