Logistics network analysis under the Belt and Road initiative: Focusing on dry port location of Qingdao port

In recent years, dry ports in China has entered into a time of rapid development, especially under the B&R initiative. In order to earn more profits and keep in the advantageous position, dry ports usually tend to rely on seaports to increase their competitiveness and attract more supplies. Sea ports are willing to cooperate with dry ports to expand their business. But, there are still some problems in the development of China's dry ports, such as unreasonable layout, serious pollution, high cost and so on. This paper is intended to develop a multi-objective optimization model, taking the economic benefits, carbon emission and transportation costs into consideration, using NSGA-II to get access to Pareto solutions to offer a possible trade-off strategy for location-allocation decision makers.
