A two-stage model for an urban underground container transportation plan problem

摘要

As a new transportation mode, underground logistics system can be used as one of the solutions to alleviate traffic congestion and air pollution on urban roads. In this paper, an underground container transport system is designed to realize the road-underground-ocean container multimodal transport. This paper first analyzes the multi-stage decision-making content needed to design the underground container transportation system from the functional point of view of transporting a container. Then a two-phase model is built. The first stage is a 0-1 planning model with the lowest single-container cost to determine the planning layout and the second stage is to construct a simulation model under the current scenario to simulate the volume of transport containers within a specified time. Finally, a case study was carried out to determine the effectiveness of the method.
