Hub-and-spoke network construction of China’s domestic coal transportation
The hub-and-spoke network structure of China’s domestic coal transportation was proposed to construct a multi-objective hub-and-spoke coal transportation network optimization model by considering both economic and environmental factors. The non-dominated sorting genetic algorithm-II (NSGA-II) was used to set 10 examples, and in comparison with the multi-objective particle swarm optimization (MOPSO) algorithm and the multi-objective harmony search (MOHS) algorithm to solve the proposed model. The results show that the effectivity of hub-and-spoke coal transportation network is effective. Compared with MOPSO and MOHS algorithms, NSGA-II algorithm can generate high-quality optimal solution in shorter time, and the total carbon dioxide emission of the optimal solution is less.
