چکیده
|
Grey verhulst models are often employed to simulate the development tendency with the characteristic of saturated process of s curve. however,the uncertainty of interval grey numbers will be increased since the boundaries of interval grey number are extended by the axiom of nondecreasing grey degree in the existing verhulst modeling method. in this paper,the interval grey number is divided into two real number parts,that is,white and grey parts. then the white and grey parts are simulated and forecasted by building the grey verhulst model and dgm (1,1) model,respectively. to some degree,this method resolves the issue of amplifying the range of interval grey number. finally,an example is used to compare the simulation performance between the new model and the traditional model,and the results show that the new model is superior to the other model. © 2013 bo zeng et al.
