In order to comprehensively simulate the behavior of antagonistic crowds,the ef-fectiveness evaluation of control strategies is essential.The media intervention model of group control is established.By introducing social dissatisfaction model and emotional model,the psychological mechanism and behavior rules of individual behavior from aggregation to escape under media intervention are revealed.In the PSO,the force analysis individual particles can reflect the relationship between control strategy and control effect.The pa-rameter analysis shows that the media properties are proportional to the dispersion rate;The medium is placed in the middle of the formation,and the dispersion rate is greater than that on both sides;The larger the group personality characteristic value,the lower the dispersion rate.Finally,a simulation experiment is designed to verify the effectiveness of the established model.The model can evaluate the effectiveness of group control strategies and provide certain decision-making support for controlling crowd violence events.
