| Abstract: | A few typical parameters of numerous parameters which affect pualitatively price of solid rocket motor were selected by correlate analysis and cluster analysis, and the gray model of price was used to estimate.The practice indicated that the method possesses higher accuracy with absolute value 1.61% of the average residual percentage.The model may be suitable for the price establishment of small samples. |
