摘要
分别采用线性回归法和支持向量机法对连云港港货物吞吐量进行预测研究,在此基础上,提出基于前两种方法的最优线性组合预测模型。通过对3种预测方法的预测结果对比,指出组合预测法具有性能稳定且精度较高的特点。最后根据组合预测模型结果,给出连云港港2010—2015年货物吞吐量的预测数据。
The linear regression method and support vector machine method are used respectively to make a prediction on the cargo throughput of Lianyungang port.Based on the two methods,an optimal linear combined forecasting model is built.By contrasting the results of three methods,it indicates that combined forecasting method is more accurate and steady-going.In the end,the final prediction of cargo throughput of Lianyungang port from year 2010 to 2015 is given according to the combined forecasting model.
