摘　　要：介绍了灰色预测的基本原理和常用GM(1,1)模型及其适用性判断方法,针对GM(1,1)模型中背景值的取法,提出了一种自动寻优定权的改进措施,通过实例对比分析,应用效果良好.In this paper, we introduce the basic theory of grey prediction and the applicability judgment method for GM (1,1) model. Aimed at the gaining background value in the model, we put forward an improved measure by auto-optimization of weight. By contra-distinctive analysis, the application effect is satisfied.
