摘要
通过优化灰导数白化值,建立了无偏灰色GM(1,1)模型。并用此模型对九江学院图书馆2004~2009年化学类图书借阅量进行了预测,结果表明,预测结果精度较高,可为图书馆图书流通管理提供更为可靠的依据。
By optimizing grey derivative whitening values,this paper set up an unbiased GM(1,1)model.Book turnover of chemical books of Jiujiang university library from 2004a – 2009a was predicted based on the new model,results showed that predicted data is credible precision and can provide convinced foundation for the book –turnover management.
