基于G(0,n)灰色关联法预测港口吞吐量

The Forecast of Port Throughput Based on G(0,n) Model

港口货物吞吐量受多因素不同程度的影响,采用灰色关联法分析各因素与吞吐量之间的关联度。根据关联度大小排除对吞吐量影响较小的因素,利用确定的主要因素数据建立G(0,n)模型,进而对港口吞吐量进行预测。对预测的结果进行残差检验。表明这种方法有较高的准确度,满足实际需求。

Port cargo throughput affected by many factors in varying degrees, the gray correlation method be used to analysis the correlation between factors and throughput .According to the size of correlation to determine the main factors, The main factors used to set G（0,n） model, and thus to predict the throughput of the port. The results will be tested and show that this method has higher accuracy to meet the actual demand.
