为提高航电枢纽工程的施工效率,在计入冰冻对航电枢纽施工影响的基础上,以施工工期最短为优化目标,以施工强度与机械设备为约束条件,构建了面向季节性冰冻河流航电枢纽的施工进度优化模型。然后,针对基础蝙蝠算法进行研究,利用混沌映射和小生境理论对其进行改进,提出混沌小生境蝙蝠算法,选择改进后算法作为模型的求解的方法。最后,结合依兰航电枢纽工程开展数值实验,结果表明:本文建立的施工进度优化模型和混沌小生境蝙蝠算法在解决航电枢纽工程施工优化问题的可行性和优越性。
In order to improve the construction efficiency of the hydropower project, taking into account the impact of freezing on the construction of the navigational junction, taking the shortest construction period as the optimization objective and the construction intensity and mechanical equipment as the constraints, Optimum construction schedule of the armature. Then, based on the study of the basic bat algorithm, the chaotic mapping and niche theory are used to improve the algorithm. The chaotic niche bat algorithm is proposed and the improved algorithm is selected as the solution of the model. Finally, numerical experiments are carried out in conjunction with the Yilan Navigation Power Junction Project. The results show that the construction progress optimization model and the chaotic niche bat algorithm established in this paper are feasible and superior in solving the construction optimization problem of the navigation and hydropower project.
