Abstract—With the rapid development of the courier industry, customers are placing higher demands on the cost and delivery time of courier services. Therefore, this paper based on the classical signal-allocation incomplete hub network design protocol to develop the optimization model for bi-objective express transportation network design problem (BO-ETNDP), which aims to minimize the operation cost and maximum arrival time. A novel bi-objective nonlinear mixed-integer optimization model for BO-ETNDP is developed considering the impact of the heterogeneous vehicles and the hub’s sorting efficiency on the operation cost and arrival time. To solve the model, a preference-based multi-objective algorithm (PB-MOA) is devised. In the case study, the applicability of the proposed methodology is verified in a real-world leading express company.
