Research on Optimization of Fresh Cold Chain Logistics Distribution Path Considering Road Impedance

Abstract

Under the condition of considering the road impedance, the mixed time window constraint is introduced to establish the optimal model of cold chain logistics distribution path of fresh food with the goal of minimum total distribution cost. Then a hybrid genetic-simulated annealing algorithm is designed, and the proposed model is solved in combination with the actual case. Through the analysis of the results obtained, it is found that the method proposed in this paper can enable enterprises to improve customer satisfaction while reducing distribution costs.
