| Abstract: | In grey system theory, the studies in the field of grey prediction model are focused on real number sequences, rather than grey number ones. Hereby, a prediction model based on interval grey number sequences is proposed. By mining the geometric features of interval grey number sequences on a two-dimensional surface, all the interval grey numbers are converted into real numbers by means of certain algorithm, and then the prediction model is established based on those real number sequences. The entire process avoids the algebraic operations of grey number, and the prediction problem of interval grey number is usefully solved. Ultimately, through an example’s program simulation, the validity and practicability of this novel model are verified. |
