东北东部地区进口铁矿石海铁联运系统优化

Optimization of imported iron ore integrated transport system in northeast China

东北东部铁路贯通后,东北老工业基地的铁矿石原材料海铁联运系统优化成为辽宁沿海各港关注的焦点。基于大量的港口、钢企、铁路数据信息,总结分析东北地区进口铁矿石海铁联运系统的现状及存在的主要问题。采用运输成本、服务水平、能耗等多目标线性规划,构建东北东部铁路贯通后东北东部地区进口铁矿石海铁联运系统的数学模型,系统提出海铁联运优化方案和对策。

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.
