SCGMmv（1,1） Model Analyse and Its Application in Forecast of Engineering Survey

分析了均值生成时序，按SCGGM（1，h）建模原理构造了基于均值生成时序的SCGMmv（1，1）模型。该模型的计算量少，预测精度较高，适应于动态过程快速建模。对工程测量的预测表明：SCGMmv（1，1）的拟合、预测效果是令人满意的。

This paper investigates a type of mean-value generating time series, and based on it constructs a forecasting model of S CGMmv（ 1,1 ） according to principle of SCGM（1,h） modeling. The obtained model of considerably high accuracy reduces calculation and is best suited for quick-modeling of dynamic process. The forecast of grain output shows the fitting and forecasting results of SCGMmv（1,1） are satisfactory.
