摘要
以我国1997-2005年农业机械总动力数据为基础,将无偏灰色预测模型应用到农业机械总动力预测中,并与传统灰色预测模型进行比较,结果反映了无偏灰色预测模型的优越性,最后预测数据显示2009年我国农业机械总动力将达到85 262.54万kW。
On the basis of the total power data of agricultural machinery from 1997 to 2005,the unbiased grey forecasting model was applied in the total power requirement of agricultural machinery,and it was compared with the traditional grey forecasting model.Result showed that the unbiased model was superior to the traditional one.Finally the predictive results showed that the total power requirement of agricultural machinery in China would reach 85 262.54×104 kW in 2009.
