Planning connections between underground logistics system and container ports

Abstract

In order to alleviate the traffic congestion inside the port cities caused by container transportation, the underground logistics system (ULS) is considered in this paper to solve the container transportation problem. By establishing port-convergence-station, the connection between the ULS and the port is realized. Specifically, the paper describes the internal layout and floor space of the port-convergence-station. Meanwhile, a robust optimization model is established to deal with the uncertainties of the carrying capacity of an ULS. Moreover, a case study based on Waigaoqiao Port Area to Logistics Park in Jiading is conducted to intuitively solve the robust optimization model to obtain the appropriate location of the port-convergence-station. And the effectiveness of establishing ULS and port-convergence-stations in the case is verified by simulation to illustrate the congestion problem in the container port area.
