摘要: 提出一种新的组合预测模型--广义加权函数比例平均组合预测模型,并利用二次规 划算法给出其加权系数的参数估计方法.同时,针对航材消耗的季节性与波动性特点,建立了航 材消耗预测的灰色系统模型与神经网络模型,最后建立了基于灰色系统与神经网络的航材消耗 广义加权函数比例平均组合预测模型并以实例说明了其预测效果.Abstract: A Dew kind of combining forecasting model based on the generalized weighted functional proportional mean is presented. And the parameter estimation method of its weighting coefficients is given by using the algorithm of quadratic programming. Meanwhile, the grey system forecasting model and the neural network forecasting model of air material consumption are proposed for its seasonal and fluctuating characteristics. Finally, the generalized weighted functional proportional mean combining forecasting model of air material consumption based on grey system and neural network is proposed and its efficiency is demonstrated by an example.
