Abstract: Emergency events often cause secondary disasters, before the large-scale external emergency resources, giving full play to the advantages of regional mutual rescueand sharing the emergency resources of the primary disaster sites for resource redistribution is one of the significant means to respond to the secondary disasters in time. This paper attempts to integrate the psychological factors of disaster victims into the supplies redistribution. Based on the prospect theory, this paper proposed the perceived satisfaction model of the primary disaster victims,described the perceived satisfaction of the secondary disaster victims with the survival probability curve, and a multi-objective optimization model considering the perception satisfaction of disaster victims on both sides was constructed by sharing the emergency resources of the primary disaster sites to support the secondary ones.In order to improve the efficiency of the model solution, the multi-objective particle swarm optimization(pso)algorithm is improved by introducing the zoom coefficient and the check function constraint. Finally, an example is given to verify the feasibility and scientificity of the model and algorithm, which provides decision support for emergency management with chain reaction.
