Control Mode of Public Emergency Response

Emergency is very difficult to be predicted since the social system has complex and comprehensive characters, so while a public emergency happens, a reasonable, efficient and timely response and control mode to be quickly selected is important to decrease the loss and to reduce the control cost. If the public emergency response agency doesn’t rapidly forecast or estimate the potential loss, an ineffective control mode would be adopted, and the emergency diffusion situation couldn’t be controlled, which would lead to the social instability. According to the different efficiency of response measure, the different control mode of public emergency response are classified into four types which are defined as lead-control mode, sync-control mode, delay-control mode and Invalid-control mode, respectively. The results show that the different cost is needed to control the emergency diffusion with different control mode, and the lead-control mode is the most efficient control model.
