%X The morbidity of model is a key condition to judge its practicability.So this paper discusses the morbidity problem in grey discrete GM(1,1) model,based on the condition number of matrix.Results show that the morbidity problem exists if the original datum are used directly in discrete GM(1,1).By means of the linear transfer,the morbidity problem can be solved easily.A example shows the method is useful.
