Simulation Analysis of Information Control for "723" Wenzhou High-speed Railway Accident in China Based on System Dynamics

Information is one of most important bases in unconventional emergency response. The paper establishes system dynamics simulation model of informational control based on the law and principle of information behavior in unconventional emergency response. A case study of "723" high-speed railway accident reveals that information channel load, information technological development, information professional level etc., have important role in emergency response. Emergency managers should pay attention to improvement of information receiving and processing to enhance emergency decision-making efficiency and rapid response capability. one of the most important bases in unconventional emergency response.
