A Fire Risk Assessment Scheme for Underground Public Building Based on FPN

With the accelerating process of urbanization, various types of underground public buildings continue to emerge, which fires occur from time to time. Compared with other public buildings, the underground public buildings fire has its own characteristics and resulted in more casualties and huge property losses. Fire prevention program of underground public buildings should take into account the unique risk and protective characteristic of these dangerous. It is the role of great importance to establish the fire risk assessment scheme for underground public buildings and to research the methodology of fire risk assessment. In this paper, the fuzzy Petri net modeling and simulation approach to the fire risk assessment of underground public buildings will be discussed based on the characteristics of underground building fire and the conclusion of the current fire risk assessment methods. The thesis discusses the object-oriented fuzzy Petri nets that are used in the field of fire risk assessment. Fuzzy Petri nets for risk assessment modeling, dynamic monitoring and simulation system design will be analyzed and researched. Finally, the fire risk assessment scheme has been used for fire risk evaluation of an underground shopping center, and the effectiveness of the scheme is verified.
