Multi-variables discrete grey model based on driver control

In the paper, a new multi-variables discrete grey model was constructed to overcome the problems that undefined driving mechanism and low modeling accuracy of grey models, though introducing rectangle function, and the parameters estimate method was discussed. Then, we proposed two identification methods for driver control function, according to the completeness of system information, and specified the modeling steps. At last, mobile telecommunication costumer number forecasting problem was solved with the proposed model. The result proves that the model is not only high accuracy, but also defined driving mechanism.
