葡萄酒和葡萄数据的统计分析方法——2012年全国数模竞赛题的实证研究

Statistical analysis methods of the grape wine and grape data——Empirical research of the a problem in 2012 National College Mathematical Modeling Contest paper

基于全国大学生数模竞赛数据,选择成对比较检验,验证了两组评酒员对红葡萄酒的评分结果不存在显著性差异,并采用分类方差法分析了第二组评酒员的评分结果更加可信。同时,运用客观权折衷型模糊决策方法,对27种红葡萄样品进行了综合评价,确定了其优劣等级。

Based on the data of the National College Mathematical Modeling Contest, paired comparison test was selected to verify that the red wine evaluation of two groups did not have significant difference. Using the method of classification variance analysis, it was concluded that the second group was more reliable. Meanwhile, adopting the eclectic fuzzy decision-making method with objective weight, we comprehensively evaluated the 27 kinds of red grape samples and determined their quality level.
