This paper reveals that GM(1,1) model is actually constructed according to the first order linearly differential equation, it is an equation that exponential sequences satisfy, so the essential of GM(1,1) model is an exponential sequence model. Though GM(1,1) model is constructed according to the first order linearly differential equation, both are not the same, this paper shows their features in common and differences. In addition, this paper proposes that models constructed according to the first order linearly differential equation are not unique, the author constructs another exponential sequence model, we might as well call it grey exponential model(GEM), it can replace GM(1,1) model for predicting of grey systems.
