摘要
本文采用灰色系统理论对湖北省粮食产量建立了灰色预测模型,较详细地叙述了建模过程,并将其结果与湖北省粮食产量的随机时序模型进行了分析对比,实际结果表明,灰色预测模型比随机时序模型提高了精度。
n this paper, on the basis of the theory of grey system, we establish grey calulation model to the output of grain in Hubei Province and give a detailed description to the process of establishing the model. We also analyse and contrast the previous result and stochastic process model of the output of grain in Hubei Province and the actual result shows that precision of grey calculation model is higher than that of stochastic process model.
