| 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. |
