The Price Estimation of Solid Rocket Engine Based on Cluster Analysis and Gray Model
基于聚类分析和灰色模型的固体火箭发动机价格模型研究

This article selects a few typical parameters from numerous parameters which influence the rocket price through correlate analysis and cluster analysis then set up the gray model of the price estimate. The practice indicates that a higher accuracy can be obtained and this model is fit to fewer samples.
