In order to study the optimal scheme of personnel evacuation after the hazardous gas leakage,quantitatively calcu-late the degree of injury suffered by personnel on each evacuation path,and rationally arrange the evacuation routes to evacu-ate personnel,a Multi-objective Optimized Emergency Evacuation Path Planning algorithm(MOEP)was proposed,which comprehensively considered the toxic gas concentration field,path relationship,actual evacuation duration and other factors,thus the path planning scheme of emergency evacuation was obtained.Taking a liquid ammonia leakage accident as a case,the evacuation schemes obtained by using only the shortest evacuation path,using only the least toxic load path and MOEP were compared to verify the effectiveness of the model.The results show that pursuing only the shortest evacuation path or the least toxic load path may lead to higher injury or longer evacuation time,and the implementation of the optimal evacuation path planning scheme in this paper can make full use of multiple feasible paths for personnel evacuation.The research results can provide reference for the emergency evacuation path planning under toxic gas leakage accidents.
