Non-Equigap GM(1,1) Model via Weakening Buffer Operator and Its Application

The present paper focus on the matrix form of the non-equigap GM (1, 1) model and its modeling mechanism with its parameter estimating via the weakening buffer operator. This paper also uses matrix formula to study the common characteristics of various forms for different weakening buffer operators. Research shows that the matrix form of this grey model is convenience to express the modeling mechanism. Finally, non-equigap GM (1, 1) model via weakening buffer operator is applied to single section traffic flow forecast, and satisfied results are achieved.
