Improved grey derivative of grey Verhulst model and its application
Based the principle and characteristic of grey Verhulst mode, the
cause of grey Verhulst models inaccuracy is analyzed , the new
formula of grey derivative is strutted and the unbiased grey
Verhulst model is given in this paper. The new modeling method
improves the simulation precision and extends the application
scope of grey verhulst model. Some examples are also given to
show that the precision of the new model is very high.
Keywords: grey Verhulst model, grey derivative, unbiased, application
