组合工况下供水管网的智能优化设计

Intelligent optimization design of the water supply network under combination conditions

基于遗传算法,首次同时考虑最高时、事故时、消防时多个供水工况,建立供水管网管径组合优化设计模型,采用C++平台实现了优化算法,通过实例应用证明,与传统的单工况优化及先单工况优化,再进行多工况校核的方法相比,计算效率有明显提高,特别是针对大规模复杂供水管网的改扩建问题,经济效益明显.

Based on genetic algorithm, consider all of the maximum hour, the emergency hour and the fire hour together for the first time, we build and realize optimal model for pipe size combination of water supply network by C＋＋ platform. Proved by examples that compared with traditional single loading case optimization, checked with multiple loading cases after single loading case optimization, the computational efficiency is increased obviously. Especially for expansion and reorganization of the large-scale and complex water supply network, economic benefit is raised obviously too.
