Theory analysis and practical application of in establishing grey model
Abstract:The primitive ordered of numbers cardinal number processing forms changes the sequence newly, from this set up the model and the traditional model which compares, may effectively reduce the primitive sequence the computation residual error, clearly raise the model precision.
Keywords: Gray model cardinal number method optimum cardinal number definite method
