摘要:

快递车辆配装问题是指车辆在各快递站点进行货物配送时将价值尽可能大的揽收货物带回配送中心。提出一种求解该问题的带限界函数分支限界算法,搜索树中待处理结点用堆结构存储,结点中存储搜索路径,用设定的搜索下界进行搜索树剪枝,实验结果验证了该算法的有效性。

Abstract:

Express vehicle assembling problem refers to the fact that vehicles bring the goods with the greatest value back to the distribution center when delivering goods at each express station. A branch and bound algorithm with bound function is proposed to solve the problem. The nodes to be processed in the search tree are stored in a heap structure and the search paths are stored in the nodes. The lower bound of search is used to prune the search tree and the experimental results verify the effectiveness of the algorithm.

Key words:

express vehicle assembling problem, knapsack problem, branch and bound algorithm
