Modeling and simulation of new product diffusion with the impact of imitation

Abstract

There is always an impact of its imitations in new product diffusion which is not reflected in the classicmodels of new product diffusion. Based on the Bass model and Steffens-Murthy model, this paper establishes a modified model with the impact of its imitations .New model has more advantages in simulating a downward trend in actual sales, and could be applied in more complex sales. The treatment of actualdata verified this conclusion. © 2012 Springer-Verlag Berlin Heidelberg.
