混沌人工鱼群算法及其在灌区优化配水中的应用

Chaotic artificial fish-swarm algorithm and its application in water use optimization in irrigated areas

对人工鱼群算法进行了改进,结合灌区优化配水问题,建立了灌区优化配水的混沌人工鱼群算法模型。通过对山东省威海市节水灌溉示范区进行优化计算,算法能有效地搜索到灌区净效益最高点,优化后与现状种植结构相比,粮食作物面积减少,经济效益较高的果树面积增大,灌区净效益提高56%。优化结果表明,混沌人工鱼群算法应用于灌区优化配水计算切实可行,为复杂的灌区优化配水问题提供了新的思路和方法。

The chaotic artificial fish-swarm algorithm is presented combining the artificial fish-swarm algorithm with water resources optimization. The chaotic artificial fish-swarm algorithm was used to solve the problem of the water utilization optimization for crops in water saving irrigation region, Weihai city, Shandong Province. The result indicates that food planting area is decreased, the economic crops planting area is increased and the net benefit is increased by 56 percent, and the algorithm can search the optimal value and the algorithm is effective and practical. The algorithm provides a new method for optimization of water allocation in irrigated areas.
