Abstract: Because the linear, secondary, cubic exponential smoothing method have different fitting degree when predicting the spares with the different consumption discipline, this paper adopts the three kinds of exponential smoothing method to predict spares consumption quota, whose smoothing coefficients take a value that makes the squared error minimum when it is in a certain range, finally selects the result, with minimum squared error among the three methods, as spares consumption quota. Prediction results show that the comprehensive application of three kinds of exponential smoothing method to predict is more accurate than single method, the research method is of higher utility and promotion.
