管道网络系统的弱关联性及其应用

The Weak Interrelationship of the Pipe Network System and Its Applications

在研究管道网络的基础上，首次引入并定义了系统弱关联的概念．利用管道网络的弱关联性，提出了一种把大规模管道网络分解成子管网进行求解的新方法——重叠分解迭代法．

A new concept, which is named weak relation system, is introduced. Based on the weak relation of the pipe network, a new method called overlapped decomposition iterative algorithm, is developed. The method can be uesd to decompose the large scale pipe network into many sub networks for optimization or analysis. The method was successfully used in the gas pipe networks.
