Abstract:

In the field of grey system theory research, it is short of the researches on grey prediction models which are based on the sequences of grey number. A prediction model based on “kernels of interval grey numbers ” is built to realize the future kernel’s prediction, and then according to the axiom of undecreased degree of greyness, and taking the kernel as the center, the upper and lower limits of an interval grey number are extended and obtained, and the prediction model of the interval grey number is built on the premise of without destroying the independence and integrity of interval grey numbers. An example analysis verifies the validity and practicability of the new model. The prediction models of interval grey numbers have a vital significance for enriching and perfecting the grey prediction model theory system, and extending the applied scope of grey prediction models.
