Processing and prediction to two examples based on the combined model of wavelet RBF neural network and the combined model of wavelet gray metabolic GM(1,1). The results indicate that a combination is superior to a single model predicted results. The prediction accuracy of RBFNN significantly affected by noise,Metabolic GM(1,1)prediction model of short-term prediction is high accuracy,and the prediction ac-curacy is unaffected when the noise is small.%应用小波去噪的新陈代谢GM(1,1)模型和小波去噪的RBFNN组合模型对两个实例进行处理和预测,结果表明组合模型预测结果优于单一模型,RBFNN预测模型的预测精度受噪声影响明显,而新陈代谢GM(1,1)预测模型对于短期预测具有较高的精度,且预测精度在噪声较小的情况下不受噪声影响。
