Joint Optimization of a Dry Port with Multilevel Location and Container Transportation: The Case of Northeast China

摘要: Dry port construction can reduce the cost of container transportation, and its location is focus existing research. Considering dry capacity limitations scale advantages, this study calculates costs associated with operations, time, environment constructs a joint optimization model transportation scheme to minimize total cost. Taking 35 prefecture-level cities in Northeast China as source goods Dalian destination, conducts an empirical analysis using Gurobi 9.0.2 optimizer AMPL software solve problem takes minimum goal select best transshipment scheme. The research draws following conclusions. Seven ports also need be built road-rail (RD-RL) mode, which shares 82.76% volume, by approximately 21.67%. Although multimodal transport through increases time slightly, it significantly economic environmental transportation.
