| 摘 要： | 本论研究的是提高灰色预测模型的一种方法。首先建立主模型进行预测，得到残差序列，然后对残差序列建模，对主模型进行修正，得到修正的GM(1，1)模型。将模型应用到原煤销售量的预测中，其精度明显提高。 |
| 关 键 词： | 灰色预测 残差GM（1，1）模型 残差序列 原煤销售量预测 |

| Abstract: | In this paper we discuss a methcd for improving the accuracy of the model of gray forecast. First we make a main model to forecast, and gain a remaining sequence. Then we establish another model on the basis of remaining sequence to amend the main model, so that we gain the amended remaining model of GM(1,1). This model is used in forecasting coal sales, and the accuracy is considerably improved. |
| Keywords: | grey forecast remaining GM(1 1) model the remaining sequence the forecast of coal sales |
