Since ancient times forecasting natural and social phenomena has became an interesting topic, which attracts attention of many experts. Currently there are over 300 different types of forecasting methods and among them the grey forecasting model is one of the simplest and most effective methods. In this thesis I will use the grey theory including the traditional grey model GM(1,1) and the non linear grey Bernoulli model NGBM for forecasting the telecommunication market in Vietnam next five years. The obtained forecasting results let us know about the reduction of the number of 2G network subscribers and the augmentation of the number of 3G network subscribers, from this our company (Viettel) will have more data for adjusting the marketing strategy and improving the quality of services.
