Abstract
The swift growth of e-commerce has intensified the pressure on the express delivery industry in terms of timely delivery. Therefore, it becomes imperative to explore the implementation of a joint distribution model that enables more efficient and sustainable delivery of express shipments. Considering factors such as the capacity of delivery stations and the number of transport vehicles, this study proposes a two-level delivery location selection model under the joint distribution mode, aiming to minimize the total cost and carbon emissions of the delivery station location selection. The proposed model is solved using the Improved Multi-objective Particle Swarm Optimization (IMOPSO) algorithm. According to the research results, by adopting the joint distribution model, the total cost can be significantly reduced to 63,867.05 yuan while also achieving a substantial reduction in carbon emissions to 997,945.81 kg. Furthermore, the facility utilization rate exceeds 90%. Notably, the IMOPSO algorithm exhibits notable advantages in terms of both accuracy and computational efficiency.
