Chen Shaodong, Song Liang

According to the data supplied by the National University Colleges Mathematics Modeling Competition in 2012, we can find that whether the grapes are good or not, and the direct relationship between the grapes and the wine quality by the help of the SPSS and other statistical softwares, by comprehensively utilizing the method of multivariate statistical analysis and then carrying out data analysis, by distinguishing the credibility that members of liquor comment on the wine quality, and by utilizing the factor analysis to make quality classification on the grapes. The physical and chemical indicators detected by wine and grapes reflect the quality of wine and grapes to a certain extent. Analyzing the relationship among the physical and chemical indicators of the grapes and wine, we establish a mathematical model evaluating the wine quality by utilizing the physical and chemical indicators of the grapes and wine, which provides some references to accurately evaluate the wine quality in practical problems.
