Robust Optimization Model of Feeder Lines Routing Based on the Hub Port Available to Purchase

This article determines one reasonable feeder-line routing for a containership fleet performing pickup and deliveries between the hub ports and spoke ports. It first analyzes the relationship between the hub port and feeder lines and then investigates how to design robust feeder lines routing. A robust optimization model with pickup, deliveries, and time deadlines is built. Improved genetic algorithms are used to solve the model. Results show that the robust optimization model can improve the robustness of the feeder lines routing and reduce the investment risk caused by the uncertainty in the feeder network design.
