| Abstract: | The present paper is aimed at research on the change of price index as the requirements of equipment construction. The forecast model is derived from the original data by use of the grey theory. On basis of analyzing model precision, grey time series model is established to make the precision increased. Upper envelope model is derived from the characteristics of our price index. This paper is of extensive practical value. |
