主 题:grey system theory prediction model interval grey number grey number band grey number layer DGM(1 1) model.
摘 要:In grey system theory,the studies in the field of grey prediction model are focused on real number sequences,rather than grey number ***,a prediction model based on interval grey number sequences is *** 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 *** entire process avoids the algebraic operations of grey number,and the prediction problem of interval grey number is usefully ***,through an example's program simulation,the validity and practicability of this novel model are verified.
