Research on Cold Chain Logistics Vehicle Routing Problem Based on Ant Colony Algorithm

In this paper, a mathematical model for cold chain logistics distribution routes that considers carbon emissions is presented. The model takes into account the fixed costs, transportation costs, refrigeration costs, and carbon emission costs associated with the distribution process. An improved ant colony optimization algorithm is proposed to solve the model. Simulation results show that the ant colony algorithm can find an approximately optimal distribution route. The constructed model and algorithm are effective and can provide reference for route decision-making in cold chain logistics enterprises.
