In the field of grey system theory, there is no the research on the grey prediction model based on the sequences
of intuitionistic fuzzy numbers. The GM(1,1) grey prediction model of the sequences of intuitionistic fuzzy numbers is
constructed by utilizing the score function and hesitant degree of intuitionistic fuzzy numbers. Then the membership function
and the non-membership of intuitionistic fuzzy numbers are obtained by the prediction model. By using the method, the
prediction of intuitionistic fuzzy numbers can be realized. Finally, an example shows the feasibility and effectiveness of the
proposed method. The grey prediction model of intuitionistic fuzzy numbers enriches the grey system theory and extends the
applied scope of the grey prediction model
