The Solutions Apply for Erroneous Grey Prediction
: Shou-Jen Huang and Chun-I Chen : Grey development coefficient, GM(1,1) grey model, L’Hôpital’s Rule.
: Singular phenomenon causes a meaninglesspredictive value outcome in GM(1,1) grey predictionmodel. It is found when the requirement of necessaryand sufficient condition of the grey developmentcoefficient a not equal zero is ignored, then theforecasting result could hold possibility of erroneousoutcome. In this research, three methods which has beenproposed in the literatures are applied to avoiderroneous forecasting in GM(1,1) grey model whensingular situation occur.
