孙兆辉 %A 白思俊 %A 刘丽华 %J 系统工程理论与实践 %D 2005 %I %X 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. %K solid rocket engine %K cluster analysis %K gray model
