混合轴辐式城乡一体化物流网络构建研究

为了降低城乡物流成本和提高城乡物流效率，以成本为导向构建了一种同时满足农产品与非农产品物流需要，并允许直达运输的混合轴辐式城乡一体化物流网络规划模型，设计了求解该模型的禁忌搜索算法。为了验证模型及算法的有效性，进行了包含6个节点的网络仿真分析和针对运输折扣系数α、β，货损系数θ₁、θ₂的灵敏度分析。仿真结果表明，选择节点4和节点6作为枢纽节点，节点2与节点3建立直达运输时，网络最优总成本为538 114；α、β分别从0增加到1，θ₁、θ₂分别从0增加到0.5，对应的网络总成本分别增加了4.1%、3.7%、4.2%、0.8%。构建的混合轴辐式城乡一体化物流网络能有效降低物流成本，提高效率，可为实际应用提供参考。

A Research on the Construction of Hybrid Hub-and-spoke Logistics Network of Urban-rural Integration

In order to reduce the cost of urban and rural logistics and improve the efficiency of urban and rural logistics, a cost-oriented planning model of the hybrid hub-and-spoke urban-rural integrated logistics network was constructed which meets the logistics needs of agricultural products and non-agricultural products and allows direct transportation. A tabu search algorithm was designed to solve the model. For verifying the effectiveness of the model and algorithm, a network simulation analysis including 6 nodes and sensitivity analysis of shipping discount coefficient α, β and loss coefficient θ₁ and θ₂ was carried out. Simulation results show that when node 4 and node 6 are selected as hub nodes and node 2 and node 3 establish direct transport, the optimal total cost of the network is 538 114. As α and β increase from 0 to 1, and as θ₁ and θ ₂ increase from 0 to 0.5, the corresponding total network cost increases by 4.1%, 3.7%, 4.2% and 0.8% respectively. Conclusion:the construction of the hybrid hub-and-spoke logistics network of urban-rural integration can effectively reduce logistics costs, improve efficiency, and provide a reference for practical application.
