Journal of Digital Information Management Yun Gao, Jiangping Zhao 15 3 2017 http://dline.info/fpaper/jdim/v15i3/jdimv15i3_1.pdf In the view of the current fire safety emergency management system construction exists many problems, we should change the treatment, prevention and early warning of ideas, innovative thinking, and expounds application of the emergency management to build and improve the fire safety emergency management system. Inspired by this principle, this paper proposes the novel computer aided fire safety engineering model based on the shortest path algorithm. In our methodology, we primary focus on the following aspects. (1) To build a fast and efficient aftermath disposal system composed of information management subsystem, the science and technology support subsystem, emergency mobilization guarantee subsystem and the rehabilitation subsystem and other functional subsystems. (2) Construction of the science highly effective emergency early warning system must establish the perfect emergency circular and the warning system that establishes the perfect emergency medical system. (3) The construction of the efficient emergency response system. We have set up the sound scientific organization system for fire control safety emergency management decision making, based on the functions of three level theories. In the future, we will apply the model into real scenarios.
