Optimization of Cargo Transportation Plan Considering Carbon Emissions

With the rapid development of global economic integration, the world’s seaborne trade volume is increasing year by year. This creates higher requirements for port construction and distribution system construction. The collection and distribution of goods through efficient systems can not only improve the circulation of goods, but also reduce and alleviate pressures such as port congestion. In view of this, it is significant to target the dry port as a transit node and consider the carbon emission optimization of cargo transportation. The paper considers the difference between the transit time constraint, the road capacity constraint, the storage capacity of the transit node, and the internal, and foreign trade in the node clearance. It establishes a mathematical model with the minimum sum of transportation, customs clearance, storage, and carbon tax cost. The effectiveness of the proposed algorithm is verified and provides an optimization plan for the carrier’s choice of cargo transportation.
