管网改扩建中管线布局和离散管径的遗传解法

Inherit Arithmetic of Pipeline-layout and Discrate Pipe-Diameter during the Rebuilding and Extending the Design of City Flow Network

供水管网系统改扩建的优化设计是一个含有混合整型离散变量的非线性规划问题 ,其中的管线布局和市售管径的直接求解 ,对单纯的数学方法说来是一直仍未攻破的难题。本文在遗传算法的基础上 ,针对该难题提出了有效的求解方法 ,有很大的实用价值。

The rebuil was and exend was optimum the design of city flow network is a non linear planning problem containing、mixing and dicrete variable.The direct solving of pipeline layout and discrele pipesdin meter.It is still a conundrum not be made a breakthrough since all along with pure math method.This paper advances some effective plans aiming at those problem basing on inherit arithmetic.It is possessed of practicality value great.
