摘要
针对社会力模型人员作用范围系数进行优化,基于模糊规则改进模型中人员作用范围,使其成为受到疏散速度、疏散人员间距共同影响的动态参数,使模型中人员可通过自身模糊经验判断实际速度、人员交互距离状态来确定心理期望作用范围。仿真结果符合真实疏散特性,证明了人员作用范围系数受人员运动状态的动态影响,并提供参考模糊规则制定原则。
The personnel range coefficient of social force model is optimized.The personnel range coefficient in the model is improved from fixed parameters to dynamic parameters affected by the evacuation speed and evacuation personnel distance based on fuzzy rules.The personnel in the model determines the range of psychological expectation through his own fuzzy experience in judging the actual speed and the person's interaction distance.The simulation results are in accordance with the real evacuation characteristics.It is verified that the personnel range coefficient is dynamically affected by the human movement state.Reference fuzzy rule making principles are provided.
