Research on Optimization of Fresh Cold Chain Logistics Distribution Route in Nanchong Considering Green Costs

In response to the practical needs of solving the distribution route problem in the fresh food cold chain logistics, this study adopts the ant colony algorithm to construct a distribution route selection strategy. By combining data analysis technology to mine key information such as customer demands, vehicle parameters, and distribution distances, and relying on the global optimization characteristics of the ant colony algorithm, an optimal planning scheme for Nanchong's logistics distribution routes with green costs as the key consideration is formulated. This scheme effectively reduces transportation costs and improves transportation efficiency.
