区域物流量预测的灰色GM(1,1)模型应用

The Gray GM(1,1) Model Applies to the Forecast of Regional Forecast Logistics Scale

介绍了灰色预测模型以及灰色预测模型在物流量预测中的应用。建立了基于灰色预测理论的GM(1,1)模型,叙述了运用GM(1,1)模型进行预测的详细步骤,并以某省物流量预测为例进行了实际应用。最后用级比检验和残差检验的方法对预测进行了检验,证明了预测的可信性。

The gray forecasting model and its application to predict logistics scale are introduced in this paper .The GM（1,1） model is set up according to gray forecasting theory and the detailed steps of the model are described. An actual application of a region s logistics scale prediction is used to illustrate the effectiveness of the model. Then, the class-compare verification and remnant verification are used to verify the result is credible.
