Abstract :
Aim at various GM(1,1)with optimum background value, a new method that consider the discrete variable k as a continuous one and let the derivative of series x(1) (k) be the original value is presented and used by the various GM(1,1) in this paper. Some examples are also given to show that the precision of all these new models are higher and the new method is possibility and availability.
