Research on cold chain logistics distribution path optimization based on genetic algorithm

With the rapid development of global economic integration and e-commerce, cold chain logistics, as a key link in guaranteeing food safety and drug effectiveness, has received increasing attention for its distribution efficiency and cost control. As an important branch in logistics, the operating cost of cold chain logistics remains high, which seriously restricts its development. In this paper, from the perspective of considering carbon emissions, time windows, cargo damage costs, and refrigeration costs, we carry out optimization research on cold chain logistics distribution paths, construct a mathematical model and algorithm improvement, and verify the practicability and validity of the model through actual cases.
