Study on Characteristics and Cloud Model Assessment Method for Kindergarten Evacuation Risk
In order to accurately assess the evacuation safety risk of kindergartens in emergencies,based on the characteristics of the kindergarten building structure and the evacuation characteristics of young children,the evacuation safety assessment index system was established by comprehensively analyzing four aspects of people,objects,environment and management.Hierarchical analysis method and variation coefficient method were used to build a comprehensive assessment cloud model,and the cloud model was used to assess the evacuation safety risk of a kindergarten in Hunan Province.The results show that the factors occupying a larger proportion in affecting the evacuation safety weight in kindergartens are emergency evacuation facilities,building level,transportation,teaching management personnel,etc.;that the overall emergency evacuation level in this kindergarten is"good",and there are weaknesses in building space layout,fire broadcasting system,and teachers'team construction;and that the comprehensive assessment cloud model can reflect the randomness and fuzzy nature of the as-sessment process and relative accurately assess the risk level of the kindergarten evacuation.The method provides a new idea for comprehensively and accurately assessing the evacuation safety risk of kindergartens.
