以锦州港1998～2007年吞吐量为原始数据,将一元线性回归预测模型与灰色GM(1,1)预测模型组合起来,采用最优权重系数法确定组合权重,对锦州港2008年～2012年的港口吞吐量进行了组合预测。
Taking the throughput of Jinzhou Port from 1998 to 2007 as the original data, the univariate linear regression prediction model was combined with the gray GM (1,1) prediction model to determine the combined weights by using the optimal weight coefficient method. From 2008 to 2012 The port throughput was combined forecast.
