摘　　要：为了全面模拟对抗性人群行为,控制策略的效能评估是必不可少的.建立群体控制的媒介干预模型,通过引入社会不满模型和情绪模型,揭示媒介干预下个体行为由聚集到逃离的心理机制和行为规律.在粒子群算法中对粒子个体受力分析,仿真结果能够体现控制策略与控制效果的关系.参数分析表明,媒介属性与驱散率呈正比;媒介放置队形中间位置,驱散率大于两侧位置;个性特征值越大驱散率越低.最后设计仿真实验,验证建立模型的有效性.模型可以对群体控制策略进行效能评估,为控制人群提供一定决策支持.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.
