To reveal the change rule of the modeling precision of grey Verhulst forecast model with multiplication
transformation acting on the sequence of raw data and reduce its modeling complexity, this paper analyzes the parameter
characteristics of grey Verhulst model under multiple transformation, and demonstrates its effect on the simulative value and
forecasting value by studying the multiple transformation acting on the raw data sequence for building this grey model. The
research results indicate that the modeling accuracy of grey Verhulst model is in no relation to multiple transformations of
raw data sequences of systems. The conclusion implies that the data level can be reduced, the course of building model can
be simplified, but the simulative and predicative results remain unchanged.
