Abstract	Accumulating method GM(1,1) model gets a new parameter estimation formula by accumulating method. But there is morbidity problem in it. In order to resolve the morbidity of the model, we analyze it in this paper based on the condition number theory. It proves that it can resolve the morbidity problem in accumulating method GM(1,1) model. With a multiple transformation on the initial data, we can get a new healthier model. Finally, it is proved that the transformation doesn't affect the precision of the model. So the model in the paper have more advantages than the traditional one.
