Abstract: In urban safety risk management, many systems can be represented by networks. In this paper, the personnel evacuation system is selected as the research objective, and the cascade failure process is modelled and simulated through the complex network theory. Firstly, based on the mutual influence of individual decision-making and overall behaviour in the network, cascading failure process is explored. Secondly, based on the random and intentional attack scenarios, we explore the effectiveness of S-C-B model at improving the system security compared to the original allocation mechanism. Through simulation, we find that due to the correlation between two subsystems, such as people, objects and management, a tiny destruction in the subsystem will spread rapidly across the network, which will lead to the large-scale destruction of the evacuation network. In addition, for human, material, management subsystems, improvement of any subsystem, can effectively cut off the accident domino effect and improve the effectiveness of evacuation.
