Food safety risk communication (FSRC) is a very complex two-way system in China and its result strongly affects public confidence level to food safety regulation. In this study, a novel system dynamics (SD) model involving five communication organizations and 36 controlling parameters is established to investigate the interactive relationships among them and the dynamical behavior of FSRC. Subsequently, the nine optimization SD models with different objective functions are developed to investigate their capacities in producing controllable and optimal FSRC strategy. The results indicate that the proposed SD model is effective for the FSRC system to make effective risk assessment, management and decisions.
