The Effect Of Software Time-locked Trail Stratege On Bass Diffusion Model

Product trail what a centuried marketing strategy is widely adopted in sofware selling,because the marginal cost of software is approximate zero and it's very easy to distribute.The trial strategy increases the number of user to enhance the influence of the product,but it erodes the potential market.In order to reduce the erosion of the market,manufacturers limit function or lock time when they distribute trail product.At present,many scholars study what infulence users' purchase intention,brand loyalty when they choose a trail product.But few scholars study the impact of product trail on product diffusion.On the other hand,the Bass model can not be fully applied to the actual situation because of the strict assumptions.Some studies on the free trial and limit function trial on the impact of product diffusion,but there is no scholars research the effect of time-locked trail on product diffusion.This paper analyzes the process of time-locked trial,and discusses the impact of time-locked trial strategy on potential market,promotion effects through learning experience when trailing,weakening effects through WOM.Then the paper modifies diffusion model and simulation which discusses the influnce of the parameters to the diffusion proces and profit.Finally,this paper puts forward the suggestions to improve the effect of time-lockd trial strategy based on the simulation results.
