Optimization Model and Algorithm Design of Rural Logistics Distribution Center Location Based on Particle Swarm Optimization

Rural logistics distribution center is an important node of logistics network. It is not only the most concentrated place of rural logistics activities, but also the direct embodiment of providing logistics services for customers. Therefore, the location optimization of rural logistics distribution center is not only closely related to the economic benefits of rural logistics enterprises, but also helps to improve the service quality of logistics enterprises. Therefore, this paper first establishes a two-level distribution center location optimization model based on users' spatial data, then proposes a solution method based on PSO(Particle swarm optimization), and compiles a calculation program based on GIS. Only by reasonably selecting the emergency distribution center through PSO algorithm can a more optimized material distribution scheme be given, thus reducing the possibility of emergency expansion. However, the location of emergency distribution centers in China has not yet formed a complete system, and there are some problems such as unbalanced layout and lack of scientific planning. Therefore, the research on the location of emergency rural logistics distribution centers has strong theoretical significance and broad application prospects.
