摘要
提出了一种基于遗传算法的水沙调度方法,为了使该方法适合于各种情况,采用模糊法确定各个目标的权系数;定义了新的交叉操作和突变操作,以保证调度结果满足期望的约束;同时为了防止解过早收敛,保证得到满足约束条件的最优解,采用基于浓度的群体更新技术来保持个体多样性。实例结果验证了其可行性。
Coordinative dispatch of water and sediment based on genetic algorithm is introduced in this paper. Considering all kinds of situations,it adopts fuzzy method to determine the weight coefficient under certain condition;in order to satisfy the restraint expected, a new operation with chiasma and sudden change is defined;at the same time, the colony update technology based on density to advoid the solve to astringe too early and guarantee to look for the optimal answer satisfying the restraint is adopted, to keep individual variety. Finally the experiment confirms its feasibility from an example.
