摘要
通过对定性影响固体火箭发动机的单价因素进行修正,进行了相关分析和聚类分析,并提取了少量且有代表性的变量作为其价格模型的参数,通过建立灰色模型作为发动机价格的预测。实践表明,这种方法具有较高精度,平均残差百分比绝对值为1.61%,适合小样本单价的建立。
A few typical parameters of numerous parameters which affect qualitatively 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.
