Abstract: Aiming at the problem of post-disaster rescue dispatch of social organizations, this paper analyzed the skills of social organizations and the emergency needs of disaster areas, proposed a post-disaster rescue dispatch model based on the strength of social organizations. Taking the rescue benefit as the optimization goal, used the improved simulated annealing algorithm to solve it. The case analysis results showed that the rescue dispatch model can effectively solve the problem of social organizations participating in rescue dispatch in disaster areas, and also verify the feasibility of the improved algorithm.

Key words: emergency rescue, social organization, dispatch rescue model, simulated annealing
