Abstract: The NSGA-Ⅱ algorithm is introduced to optimize the overall arrangement of landports and seaports in Fujian Province. The objective of the optimization is set as minimizing logistic costs, carbon emissions and landport construction costs. The problem is solved by means of NSGA-Ⅱ algorithm. 16 landport construction plans with corresponding logistic arrangement of the economy hinterland are generated. The research indicates that the more landport is constructed and the larger the scale of the ports are, the lower logistic cost can be achieved, as well as the lower carbon emission. Development of the network will allow 14.14% reduction of carbon emission cost and 5.54% reduction of logistic costs.
