摘要
通过6个典型测试函数对新型优化算法——风力驱动优化(WDO)算法进行仿真验证,仿真结果与布谷鸟搜索(CS)算法、差分进化(DE)算法、混合蛙跳算法(SFLA)、粒子群优化(PSO)算法、蚁群优化(ACO)算法、帝国竞争算法(ICA)和模拟退火算法(SA)的寻优结果进行比较。选取水资源开发利用率、降水量等10个评价指标,应用风力驱动投影寻踪模型(WDO-PP)计算文山州2006年~2015年水资源承载力,并对其变化趋势及规划水平年2020年、2030年水资源承载力进行预测及评价分析。结果表明:(1)无论是单峰还是多峰函数,DWO算法寻优效果远优于CS、DE、SFLA、PSO、ACO、ICA和SA算法,具有较好的寻优精度、收敛速度、极值寻优能力以及收敛稳定性与可靠性。(2)WDO-PP模型对文山州2006年~2014年水资源承载力评价结果均为基本可承载(Ⅲ级),2015年评价结果为可承载(Ⅱ级)。水资源承载力随时间呈提升趋势,且提升趋势显著。对规划水平年2020年、2030年水资源承载力预测评价结果分别为可承载(Ⅱ级)和绝对可承载(Ⅰ级)。模型及方法具有一定的可操作性和有效性,可为区域水资源承载力计算分析提供新的思路和方法。
Through six typical test functions for new optimization algorithm- a wind-driven Optimization(WDO) algorithm simulation, the simulation results and cuckoo search(CS) algorithm, differential evolution(DE) algorithm, SFLA(SFLA), particles swarm optimization(PSO) algorithm, ant colony optimization(ACO) algorithm Empire competition algorithm(ICA) and simulated annealing(SA) algorithm for optimizing the results were compared. Select 10 index utilization of water resources development and precipitation, wind-driven applications Projection Pursuit Model(WDO-PP) Calculation Wenshan 2006 to 2015, water resource, and the level of its trends and Planning 2020 in 2030 water resource forecasting and evaluation and analysis. The results showed that:(1) either unimodal or multimodal function, DWO algorithm optimization result is much better than CS, DE, SFLA, PSO, ACO, ICA and SA algorithm has better accuracy optimization, convergence rate, seeking extreme value excellent ability and convergence stability and reliability.(2)WDO-PP model Wenshan Prefecture from 2006 to 2014, water resources bearing capacity evaluation results are basically capable of carrying(grade Ⅲ), 2015 annual results of the evaluation to be carrying(Ⅱ grade). Water resources carrying capacity over time, the trend was to enhance and upgrade a significant trend. Planning level 2020 and 2030 water resource prediction and assessment results are to be bearer(Ⅱ grade) and Absolute bearing(Ⅰ level). Models and methods have certain operability and effectiveness of regional water resources carrying capacity for computational analysis to provide new ideas and methods.
