摘要
提出了用于预测垃圾产生量的变权重组合预测模型,该模型通过把单项预测模型进行组合分析,以误差平方和最小为准则,求出最优加权组合系数,建立组合预测模型.通过实例分析,表明其预测精度高于各单项模型预测值,在城市生活垃圾产生量的预测工作中有一定的应用价值.
This paper introduces a variable-weight combined forecasting model applied to MSW (municipal solid waste) output forecasting. The method combines the forecasting models available one by one and uses the practical guide line based on the minimal sum of error square values, then gets optimal weight coefficients of combining forecasting and sets up the optimal combining forecasting model. A case study indicated that the model is more accurate than any single forecasting models and is applicable in forecasting of MSW output.
