灰色预测是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，从而预测事物未来发展趋势的状况。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。(Grey prediction is dissimilarity between the development trend by identifying system factors, namely, correlation analysis, and the original data generation processing system to find the regularity of change, to generate a data sequence strong regularity, and then establish a differential equation model, and predict the future development trend from the state of affairs. Grey prediction is a method to predict the system with uncertain factors.)
