灰色系统理论是我国华中工学院自控计算机系邓聚龙教授创立的_门新科学,已得到国际上的承认。灰色预测采用的数学模型是一种连续的微分方程。其方法是将灰色系统已知的时间序列作某种变换得到新的时间序列,称为生成序列。其生成序列都是按指数形式变化的,能用微分方程来描述,称为动态模型,Dynamic Mob简称DM,用微分方程描述的过程称为动态过程,预测中常用1阶1个变量的模型,记为DM(1,1)。 The theory of gray system is a new science that was founded by Prof. DENG Ju-long, a self-control computer department of Central China Institute of Technology. It has been internationally recognized. The mathematical model used in gray prediction is a continuous differential equation. The method is to transform the known time series of gray system into a new time series, which is called generation sequence. The generated sequences are all exponentially changing and can be described by differential equations. They are called dynamic models, and Dynamic Mob is called DM. The process described by differential equations is called dynamic process. The model with first order and one variable is often used in forecasting. Denoted as DM (1,1).
