摘要: 对于求解带时间窗口车辆路径问题,提出一种融合邻域搜索策略的改进蚁群算法,针对时间窗口特性,将等待时间加入到蚁群算法的状态转移规则之中。为提升算法的局部寻优能力,设计多种节点删除操作和插入操作对得到的路径进行邻域搜索。最后利用Solomon标准算例对改进算法进行测试,与目前已知最优解对比,实验结果表明改进后的蚁群算法对带时间窗口的车辆路径问题有较好的适用性。

Abstract: For solving the vehicle routing problem with time windows, this paper proposes an improved ant colony algorithm that integrates neighborhood search strategies. In view of the time window characteristics, the waiting time is added to the state transition rule of the ant colony algorithm. In order to improve the local optimization ability of the algorithm, a variety of node for deletion operations and insertion operations are designed to search the neighborhood of the obtained path. Finally, the improved algorithm is tested using the Solomon standard example, and compared with the currently known optimal solution. The experimental results show that the improved ant colony algorithm has good applicability to the vehicle routing problem with time windows.
