Being different from the typical direct modeling method and optimizing methods of background value, we use trapezoid formula and central difference quotient methods to whiten grey derivative and propose a grey modeling method for non-equidistant sequence based on the criteria of the minimum square error sum. The results show that the new model's fitting precision and prediction precision is improved.
Algorithm of grey numbers and grey algebraic system is the theoretical basis of grey system theory. It is possessed of very important significance in the developing course of grey system theory. A definition for grey "Kernel" has been put forward. The axioms for algorithm of grey numbers and a grey algebraic system is built based on grey "Kernel" and the degree of greyness of grey...
