The accuracy of prediction willdirectly influence whether we can work out a reasonable plan and management measures. The paperintroduces the principle of exponential smoothing method and seasonal decomposition, and the process isdetailed using SPSS. The results indicate that the predictions are reasonable and reliable, and the methodsare fitting for the time series analysis.
