Novel Data Processing Mechanism of Grey Control Model

Grey generating is one method of transforming the grey process into white process. It can provide middle information for grey forecasting modeling and weaken the randomness of the raw data. This paper studies the data processing mechanism of grey control model. Based on the traditional method of accumulated generating operation (AGO), three novel data processing methods, i.e., r-AGO, opposite-direction AGO, and generalized AGO are studied, and their good properties are discussed. Therefore, this paper widens the range of grey generating methods.
