Abstract  

Increased urbanization, high-density urban populations and large urban areas have increased the importance of urban security planning. The People's Republic of China has established the Ministry of Emergency Management to study urban emergency management systems. This study reviewed urban emergency management systems in the United States, the United Kingdom, and Japan to identify three types of urban emergency management mechanism models and the corresponding emergency management models. Multi-agent simulations were then used to simulate these three emergency management mechanisms and evaluate their efficiencies. The results show that the "integrated" mechanism gives more reasonable task assignments and function divisions while the "communication" mechanism is more fluid and provides more orderly communications and decision-making.

Keywords urban emergency management      multi-agent simulations      management mechanisms      emergency

3种模型描述

模型 模型描述 模型图示 模型依据
基本模型 通常情况下的部门关系 通常情形下的部门关系
“整合型”模型 将决策和执行分离,将决策集中到一个部门中 参考美国、日本的应急管理体系
“协调型”模型 各个部门保留了各自运行模式,通过与协调部门的沟通协调,来实现合作 参考英国基于论坛的应急管理体系
