An information dissemination model of product quality and safety based on scale-free networks
In the small-world model, information nodes positions are relatively ordered. However, information dissemination between nodes is unordered on the Internet. In this study, a product quality and safety information dissemination model on the Internet is proposed in terms of the characteristics of the scale-free model in the complex network. Using the simulation tests, we found that the information diffusion rate will speed up and the time needed for the system to reach the equilibrium will shorten when the spontaneous dissemination coefficient increases. Additionally, the scope of information coverage also increases as the systems size increases. However, the time of information diffusion needed to cover the maximum area does not change with the systems size. The medias influence has also been found to have an effect on the information dissemination.
