Abstract

The invention discloses a crowd evacuation simulation method and a device based on optimizing positive emotion infection. For the trust relationship between individuals, an emotional contagion networkis constructed; For the emotional contagion network, a positive emotional contagion model is constructed. The process of emotional infection was analyzed in a parameterized manner, and the infectionprobability of each node in the emotional infection network was calculated by using continuous-time Markov chain. Construct the optimization model of maximizing positive emotional infection; Using artificial bee colony optimization emotional infection algorithm and the infection probability of each node, the optimal objective function value of a given groomer in the model of maximizing positive emotional infection optimization problem is calculated. Using the optimal objective function value of the given dredger, the optimal position of the safety dredger can be calculated. The present disclosure provides guidance for crowd evacuation by leveraging optimized positive emotional contagion, provides new solutions to public safety issues, and provides guidance for emergency management.

Description

technical field [0001] The present disclosure relates to a crowd evacuation simulation method, in particular to a crowd evacuation simulation method and device based on optimizing positive emotion infection. Background technique [0002] In recent years, natural disasters and man-made disasters have occurred frequently. In such a crisis situation, negative emotions such as panic and anxiety will spread among the crowd. How to calm the panic of the crowd by optimizing the positive emotions of the safety guides, so as to achieve an orderly evacuation of the crowd and avoid major accidents is a very challenging problem. [0003] Positive emotion contagion mainly refers to the process of individuals recovering from negative emotions under the influence of a security counselor. However, the current method has not yet considered how to best use the positive emotions of the safety guides to calm the panic of the crowd and reduce the potential threat of crowd panic, crowding, stam...
