Abstract:The existing research results of grey prediction model are all based on real numbers or interval grey numbers, and
it is short of an effective research of grey prediction models based on discrete grey numbers. Therefore, this paper respectively
constructs grey prediction models based on the kernels and areas of grey cell grid, and then deduces a novel prediction model
based on a discrete grey number sequence. An application analysis verifies the effectiveness and practicability of the proposed
model. Prediction models of discrete grey number have a vital significance for enriching and perfecting the grey prediction
model theory system, and extending the applied scope of grey prediction model.
