煤炭需求预测模型分析
nalysis of Prediction Model on Coal Demand
基于回归曲线拟合，灰色预测和最优组合模型，建立了全国煤炭需求量的预测模型，并利用各模型预测了全国2009年的煤炭需求量。最后，对三种模型的预测结果作了分析，得出结论：最优组合预测模型从总体上起到了提高预测精度的作用，用此方法进行预测是有效的，预测的结果是可信的。
Based on the model of regression curve fitting, gray prediction and optimal combination, models for forecasting coal demand are built, With the model , the prediction of coal demand is made for 2009.Finally, the predictable results of the three models are discussed, come to the conclusion: the optimal combination forecasting model on the whole plays a role in improving prediction accuracy, using this method is effective, the predictable results are credible.
