On the basis of time?series studies of spare parts demand, combining the characteristics of exponential smoothing and Croston method, the paper analyses the principle of the exponential smoothing and the two?step. Through the study of ex?ponential smoothing and variance of the two?step method, it obtains that the two?step method is the general form of exponen?tial smoothing method., which provides a theoretical support for the further study of the two?step method.
