Prediction Model of Interval Grey Number Base on Attitude Index

According to the fact that traditional grey prediction models are only appropriate for forecasting real number sequence but not for interval grey number sequence,by introducing the attitude index of decision maker,the interval grey number sequence is transformed into sequence with attitude index when the attitude index of decision maker is known,the sequence with attitude index is transformed into real number sequence.By embodying the attitude of decision maker and building grey prediction model for real number sequence with the attitude index of decision maker,an interval grey number prediction model with attitude index of decision maker is proposed.As the decision maker can build grey prediction model through adjusting the attitude index,model prediction is more practical.Finally,a practical example is given to illustrate the proposed model.
