基于灰色系统理论的大连港口物流需求预测

Demand Forecasting of Logistics in Dalian Port Based on Grey Theory

作为"一带一路"战略的关键节点,大连港口承担着重要的货物中转和疏散的任务,其中港口物流的规模有着举足轻重的作用,基于大连港口近几年的物流需求,运用GM(1,1)预测模型,对大连港口的物流需求规模进行预测,预测结果表明未来五年大连港口的物流需求持续增长,为港口物流决策提供了依据。

As a key node in the ＂One Belt and One Road＂ strategy, Dalian port undertakes an important cargo transship- ment and evacuation task, in which the size of the port logistics has a pivotal role. Based on the logistics demand of Dalian port in recent years, used GM （1.1） to forecast the Dalian port logistics demand scale. Predicted results show that in the next five years of Dalian port logistics demand contin- ues to grow, which provides the basis for the port logistics decision.
