摘 要: | 针对滨海地区水资源系统的特点,以加权相对总缺水深度最小和系统供水总成本最小为目标,建立了平原河网、平原水库群和远距离调水工程体系的水资源多目标优化调度模型;利用多目标粒子群算法(MOPSO)求解,提出了各类约束条件的处理方法,并得到非劣解集;采用距理想解欧拉距离最小准则,得到最好权衡两个目标的最佳协调解,并取得相应的调度结果。以江苏沿海为背景开展实证研究,验证了所建模型和求解方法的有效性。

Abstract: | The conflict betw een w ater supply and demand become mo re and more ser ious in co ast al ar ea of our co untr y. There2
fo re, it is meaningful t o make optimal and jo int operatio n o f limited fresh water resources so as to r eliev e t he conflict.With the
objectiv e of minimizing the w eig hted sum of wat er deficit and the to tal w ater supply cost, a w ater resources multi2o bjective opti2
ma l operat ion model was established accor ding to the char acter istics o f the co astal area water r eso ur ces system. T he system con2
sists o f water supply pro jects in plain r iver netwo rks, r eser vo irs and a water div ersion project . A mult i2objectiv e part icle swarm
optimization alg or ithm w as emplo yed to solving the mo del, the approach of pr ocessing v ario us types o f constrains was pr oposed,
and the pa reto so lutions wer e obtained. The best coo rdinated solution for the tw o g oals w as o bta ined based o n the rule that the
Euler distance fr om the ideal so lutio n is m inimum, then the co rr esponding operatio n results wer e ga ined. The case study w as
carr ied o ut in t he coastal areas of Jiangsu prov ince, which pro ved t hat the pro po sed method is effective. |
