After the occurrence of sudden public emergencies, risks propagate throughout the entire supply chain network, triggering a domino effect. Therefore, determining appropriate strategies to intervene in and control risks, thereby blocking or mitigating their spread, becomes critically important. This study constructs a risk control model for complex supply chain networks under sudden public emergencies based on the SEIR system dynamics propagation model, incorporating risk immunization strategies and government participation in risk control. The proposed model adopts a target control approach to manage risk dissemination, and the effectiveness of this approach is verified through simulation experiments. The findings reveal that target control can effectively contain risk propagation, and enhancing the risk immunity of supply chain networks during sudden public emergencies significantly reduces the extent of risk diffusion while lowering the cost of government intervention.
