摘要
该文将组合预测模型应用到决策支持系统中。给出了粮食产量预测的常用模型,通过加权组合,进而确定组合预测模型以提高预测精度。算例结果表明,该组合预测模型在预测准确性方面能得到改进,对于决策支持系统的预测有着重要的参考价值。
In this paper,combination forecasting model will be applied to decision support systems. Given the commonly used food production forecast model,with the aid of a weighted combination of prediction model to determine the combination, the prediction accuracy will be improved.The results of the cases show that the combination forecasting model in forecast accuracy can be improved. It is of important reference value for the prediction of decision support system.
