| 摘 要： | 依据某公司的实际数据,利用启发式贪婪算法求解所构建的模型,先求出子网模型的解,然后并用分枝定界和回溯法来求解子网模型,提高求解效率.计算结果表明：采用混合轴辐式的运输网络优化后的成本比优化前少,降低了3.5％.与此同时,本模型减少了中途停靠点,节省了运行时间,提高了效率.

| Abstract: | Combined with the extended hub-and-spoke transportation networks theory,this paper established a cost-minimizing decision-making model,and the model consisted of main net and subnet model.According to actual data from some actual company,solved the model based on the heuristic greedy algorithm,and firstly got the solution of the subnet model,and then,got the solution of main net model with branch and bound algorithm and backtracking method,it was better for improving solution efficiency.The computation result shows that：the extended hub-and-spoke transportation networks optimized cost less than before optimization,reducing by 3.5％.At the same time,reducing the half-way stops will save more time,and reduce cost while improving efficiency.So the model is feasible and has a strong practical value. |
