The changing of initial condition does not affect the simulative value of GM(1,1) model.Simulative value is an exponential model when actual sequence is nonnegative increased.Practical examples are used to validate the effectiveness of proposed GM(1,1). For traditional grey model (GM(1,1)), it is proved theoretically that the initial condition is not utilized, and the simulative value is convex and increased or is the decreased and concave when the actual sequence is nonnegative increased… CONTINUE READING
