英文摘要
Singular phenomena cause a meaningless predictive value outcome in GM(1,1) grey prediction model. Obviously, it will be found when the requirement of necessary and sufficient of the grey development coefficient a not equal zero is ignored and the result is integrated into the prediction equation. The research applies the effectiveness of solving methods to avoid erroneous prediction in GM(1,1) grey model which sampling four figures as raw data when the second and fourth figures are identical.
