Network Evolution Model Research On New Product Diffusion

With the economic globalization and the rapid development of modern science and technology,new product development and promotion to the market successfully are the guarantee of an enterprise survival and development.With the development of complex network research,based on complex network research,new product diffusion problem causes great interest.This paper focuses on the new product diffusion network evolution.New product diffusion in the crowd can be abstracted into network,as the more individuals understand new products,a gradual increase in network size,the relationships are changing at the same time,so consider four evolutionary mechanism of network:add node,reconnection,add and delete side.At each time step at a certain probability choose one of the four kinds of operations.Consumers limited within a certain area,the network scale in the later of the saturated state,so add some operation probability is not constant,but in change,in this kind of change is given two assumptions,by using the mean field method and Markov chain method and the corresponding degree distribution,and do the corresponding validation and application instance.Highlight of this paper is to the evolutionary network established on practical application background,and provides a basis for further research on new product diffusion,and gives the examples of applications;Different from previous studies,consider adding the change of operation,more in line with the actual situation,the more general.
