Abstract: Optimization of low-carbon regional logistics network is important foundation of low-carbon logistics system. A bi-level optimization model, considering the game between low-carbon route planning of government and enterprise, is proposed for regional logistics transportation network based on low-carbon concept. The total cost of all cost, time and carbon emission is the smallest through optimization of upper-level model of regional logistics network. On the other hand, the lower-level model, about revised Logit route choice model of goods transported, is used to solve the upper-level model goods transported. The network deformation and genetic algorithm is used to solve the bi-level optimization model. The simulation results show that the model and algorithm are correct and feasible, which benefits for low-carbon logistics network construction by its useful conclusions.
