The Price Estimation of Solid Rocket Engine Based on Cluster Analysis and Gray Model

SUN Zhao-hui,BAI Si-jun,LIU Li-hua(Management School,Northwestern Polytechnical University,Xi'an 710072,China)  
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.
