摘要
将灰色预测应用于可重复动态测试过程,根据可重复动态测试的特点,采用统计方法有效地减小随机误差的影响,用其平均值建立预测模型,并对产生预测误差的各种因素加以分析,采用统计所得的各点方差值建立预测值精度的估计模型。实例证明,误差预测模型及精度估计模型都具有较好的效果。
Applies grey perdiction to repeatable dynamic measurement. On the basis of
the features of repeatable dynamic measurement, adopt statistical method to reduce the effect of
stochastic error effectly. And adopt the average value to set up the prediction model. Then
analyzes the factors that can produce the prediction error, adopt the variance that have been
gotten from statistical compute to set up the estimation model of predicted value's error. the given
example has proved that they all have fairly effects.
