摘要
油菜产量的准确预测对油菜种植面积有重要的指导价值。将能排除数据干扰性的弱化算子引入GM(1,1)模型,建立了基于改进的GM(1,1)模型的我国油菜产量预测模型,最后通过实例演算,运用改进的GM(1,1)模型预测我国油菜产量具有较高的预测精度。
Nicety rapeseed output forecast has vital guidance value for rapeseed crop area.By introducing the buffer operator to deal with the data's disturbance,a rapeseed output forecast model is built based on improved GM(1,1) model.Finally,through the example calculation,it is found that the improved GM(1,1) model could precisely predict the rapeseed output.
