摘要
论文以秦皇岛港1991~2005年煤炭吞吐量数据为基础,采用统计预测中的GM(1,1)和三次指数平滑两种模型分别进行预测,并比较了预测结果,得出优选模型。
This paper based on data of coal port throughput of Qinhuangdao port, adopts the GM (1,1) and the Cubic exponential smoothing method to predict respectively, and compares results of the two methods, gets the optimization finally.
