Derivative Reduction Value Base on the GM (1,1) Model with Optimum Grey Derivative
並列摘要
This paper breaks through the restriction that ”grey derivative is still x(superscript (0)) (k)” in the existing method of derivative reduction value in the forecast approach, and applies the existing method of derivative reduction in the forecast approach to the case: Optimize the gray derivative of grey model or optimize the gray derivative and the background value of grey model at the same time. Through making comparison on simulation accuracy of the standard index series and the data from reality, the author displays the feasibility and superiority of the new method.
