At present, some scholars in China have studied the optimization of logistics distribution path and low-carbon logistics in Lianjing retail industry. Niu Chen put forward the ideas and methods of constructing a low-carbon distribution system for chain retail companies from five distribution links, but only based on the traditional logistics distribution center location model and distribution route optimization model. The line selection integer programming model does not take carbon emission costs into the model's objective function for consideration. Wang Dawen used the mileage saving method to optimize the distribution logistics of supermarket chains, but did not consider the distribution cost in the optimization process, and only took the shortest distribution path as the goal. Song Jiajin reduced carbon emissions into costs, and built a vehicle cold chain distribution path optimization model for fresh products that takes carbon emissions into account with minimum total cost as the objective function under the constraints of vehicle load and soft time window.
