Research on layout optimization of logistics network of metropolitan area based on hub-and-spoke theory

Abstract

In order to give full play to the role of regional logistics in the regional economic development of the metropolitan area, a kind of hub-and-spoke regional logistics network based on hub-and-spoke model was established, which has the characteristics of hub-and-spoke network scale economy, scope economy, density economy and structure economy. Seventeen technical and economic indicators are sorted out from regional economy, industrial and commercial development, transportation infrastructure development and logistics industry development, and 35 counties and districts in the Capital metropolitan area are used as the research objects in 2020. The model is used to determine the network layout among node cities and to optimize the logistics network in the Capital metropolitan area.

Research on the optimisation problem of goods allocation in logistics network based on simulated annealing algorithm

“…Facing the problem of distributing goods in unexpected situations that exist in logistics networks, Li Qi [2] By summarising the excellent scholars' papers in the extranet, it is believed that 3PL logistics model can achieve the reduction of the total cost of logistics network through the overall number of linear optimisation model. Nana Wang [3] Considers that the hub-and-spoke network has certain advantages, and reduces the logistics cost by reducing the empty rate, so as to improve the efficiency of logistics activities. Li Zewen [4] It is believed that the simulated annealing algorithm uses the probabilistic selection method in the process of searching for the optimal solution, has the flexibility of choosing the optimal solution, has a strong ability to search within the global range, and has a good, multi-location search ability.…”
