基于自动生成策略的供水管网抗震优化算法

以管网年费用折算值为优化目标、管网拓扑结构与管径为优化参数、管网节点抗震可靠度为约束条件, 建立了供水管网抗震优化设计模型.基于自动生成策略，并结合环形管网判断方法，分别利用遗传算法、遗传模拟退火算法和微粒群算法进行了供水管网的抗震拓扑优化分析.利用3种优化方法对2个典型供水管网进行了对比分析.对比分析表明，遗传模拟退火算法具有最好的优化能力.
Taking water distribution network’s annual reduced cost as optimization object and seismic reliability as optimization restriction, a network topology optimization model is established. Then, an automatic generation strategy based on the existed road information is proposed. Combining with ring network generation method and automatic generation strategy, three approaches, a genetic algorithm, a simulated annealing genetic algorithm and a particle swarm algorithm, are employed to solve the seismic optimization model. Two networks are optimized using three algorithms and a comparative study is performed. The comparison indicates that the simulated annealing genetic algorithm performs the best
