灰色预测是一种对含有不确定因素的系统进行预测的方法。灰色预测通过鉴别系统因素之间发展趋势的相异程度，即进行关联分析，并对原始数据进行生成处理来寻找系统变动的规律，生成有较强规律性的数据序列，然后建立相应的微分方程模型。(Dissimilarity trends, namely, correlation analysis, and generate raw data processing system to find the law changes, generate a strong regularity of the data sequence, then the corresponding differential equation model.)
