NSGA-Ⅱ在克拉玛依市水资源优化配置应用初探

The NSGA- Ⅱ Application Optimization Allocation of Water Resources in Karamay

在经济、社会不断发展的今天,水资源供需矛盾在克拉玛依市白杨河流域显得尤为突出。基于多目标遗传算法原理与水资源可持续发展理论,针对克拉玛依市的供水关系、水资源特征以及水资源开发利用现状,将遗传算法、多目标优化问题和Pareto非劣解集理论相结合,建立克拉玛依市水资源多目标优化配置模型;通过一系列满足不同条件的解集,选择出在不同环境条件下的可适用的方案。结果表明,通过NSGA-Ⅱ遗传算法的计算,达到经济效益最大化,并且缺水量最小,具有较好的优化效果,结果合理可靠,可为克拉玛依未来城市规划和发展提供依据。

With the development of social economy,the contradiction between supply and demand of water resources is becoming more and more prominent in Karamay Baiyanghe River. The paper is based on multi- objective genetic algorithm principle and the sustainable development of water resources theory,the light of the regional water supply of Karamay relations,the characteristics of water resources,the water resources development and utilization of the status quo,using genetic algorithm and intelligent control of multiobjective optimization problems with Pareto non inferior solution set theory combining objective optimization,establishes a multi- objective optimal allocation model of water resources. The model can meet the needs of different conditions to obtain a series of solutions,provides various in different conditions of flexible alternatives. Results show that through the calculation of the NSGA- Ⅱ genetic algorithm,to maximum the economic benefits and the minimum amount of water,with better optimization results,the result is reasonable and reliable,can provide the basis for future urban planning and development Karamay.
