A Study on Location of Logistics Hubs of Hub-and-Spoke Network in Beijing-Tianjin-Hebei Region

Through the analysis of the logistics operation scene in Beijing-Tianjin-Hebei region, a hub-and-spoke regional logistics network with four modes of transportation was constructed. Considering the network balance factor, the number of network hubs should be determined. Then, with full consideration of various factors including fixed cost, transshipment cost and integrated transportation advantages, the hub-and-spoke logistics network location model is established. We design the corresponding genetic algorithm to solve the location problem of Beijing-Tianjin-Hebei regional logistics network hub. Finally, the feasibility of the model is verified by the actual logistics operation data of Beijing-Tianjin-Hebei region, and the optimal layout of regional logistics hub is calculated. According to the analysis of the final logistics hub layout, we can find that 7 selected logistics hub in Beijing-Tianjin-Hebei region are distributed evenly. In terms of Beijing, the 3 selected logistics hubs in the city are located in the north, southwest and east west areas, which form a stable triangle covering Beijing-Tianjin-Hebei region. In terms of Tianjin, the 2 selected logistics hubs play an important role in connecting Tianjin with the surrounding cities around the region. In terms of Hebei, the 2 selected logistics hubs serve the southern region as well as cross-regional logistics operations.
