Introduction of Bass model, stochastic Bass model and Generalized Bass model with different applications

The Bass diffusion model was developed by Frank Bass and describes the process of how new products get adopted as an interaction between users and potential users. Because of the many uses of Bass model, other type of this model such as stochastic bass model and Generalized Bass Model Studied. In this paper we study and Review all models which are related to bass model. Guseo and Dalla Valle have introduced and Guidolin has applied a new approach following perturbed life-cycle diffusion models, for joint effects of economic and strategic or technological interventions by using a Generalized Bass Model (GBM) for World oil depletion. In this model, we can see, oil shocks that happened in 1973, 1979,1986 also effect crude oil production in Iran.
