Land port logistics hub is a significant logistics infrastructure which combines the intermodal transport, storage, consolidation etc. Unlike general facility layout planning issues, internal and external traffic organization has an important influence on the layout of land port logistics hub. This paper constructs a traffic network of logistics hub considering truck travel time which distinguished various types of intersections. And we propose a multi-objective model with the objectives of minimizing total truck travel time and maximizing internal correlations. Transit distance and time are both considered in total truck travel time. According to the characteristics of land port logistics hub, several constraints have been added to the model, including the coverage of existing facilities, facilities’ size, direction, and entrances’ location. Then, we design an improved algorithm based on NSGA-II, which applied multiple mutation methods and slicing tree for chromosome code. The experimental results suggest the designed algorithm is effective, and the layout scheme is reasonable.
