摘　　要：利用改进后的变精度粗糙集模型(VPRS)分析“消费者决策心理调查问卷”,样本包括910个大学生.通过设置一定的变精度值使得边界消失或接近消失,然后建立决策矩阵,构造布尔函数,应用吸收律进行化简,从而提取出男女大学生各自的消费决策最大通用规则,并且对这些规则进行了比较分析.实验表明,与经典粗糙集模型相比,该方法计算出的分类预测的准确率有了提高,且提取的规则更加简化,说明该方法是可行的.The improved variable precision rough set model （VPRS） is applied to analyze “the questionnaire of customer’s decision-making psychology”. The sample includes 910 undergraduate students. At first, an appropriate variable precision value is set, the boundary area would disappear or nearly disappear. Then a decision matrix is set up and some Boolean functions are constructed. Some simplified rules are obtained by using absorption law. At last, some maximally general rules about male and female undergraduates＇ decision making are extracted respectively. It was shown that, compared with classical rough set theory, the classification rules forecast precision is improved, and that the rules extracted are much simpler. It shows that this method is feasible.
