摘要
在对数据进行分析的基础上,运用统计方法建立超期数的分布矩阵模型,然后根据各种图书的种类和超期天数对超期原因的影响,运用了加权的思想,利用经验数据分别对不同类别和超期天数的3种原因进行加权赋值,从而得到超期原因矩阵模型。
On the basis of analysis of the data,the statistical method of data mining is used to establish matrix model of the distribution of recalled books.According to the causes of various types of recalled books and extended days,weight theory is used to evaluate the major three reasons by use of empirical data to get the matrix model.
