干线运输的车货匹配及车辆运输路径优化对于降低大规模、多分布网点的物流企业的运输成本有重要意义。建立了干线运输的发车费用模型及总费用模型,提出应用一种基于直达网络搜索和车辆行驶路径搜索的两阶段局部搜索启发式算法进行求解。通过对企业实际数据的计算,表明该算法优化了干线运输的运输路径,减少了运输车辆数,降低了运输总费用,具有较好的应用前景。
The matching of main line transportation and vehicle transportation route optimization is of great significance for reducing the transportation cost of large-scale and multi-distribution network logistics enterprises. The starting cost model and total cost model of trunk transportation are established. A two-stage local search heuristic algorithm based on direct network search and vehicle driving route search is proposed to solve the problem. The calculation of the actual enterprise data shows that the algorithm optimizes the transportation route of trunk transportation, reduces the number of transportation vehicles and reduces the total transportation cost, and has a good application prospect.
