After Northeast Eastern Railway’s connecting，how to optimize the original sea-train transport structure of the imported iron ore in the northeast region has become the focus of each port across Liaoning coastal.The article analyses the profiles of the importing iron ore integrated transport system，and summarizes the existing problems of its railway transport system development.The optimal transport program is computed through the multi-objective linear programming mode，such as the transportation cost，service level，energy consumption，etc.It poses the low-cost transportation solutions of the iron ore imports transport system，and researches the countermeasures of optimizing the transport system construction in the east of northeast China.
