Abstract

Abstract:

In order to improve the fire risk assessment level of the air film stadium, identify fire hazards in time and reduce fire risks, a fire risk assessment model based on the game empowerment regret theory was constructed. The improved analytic hierarchy process(AHP)and entropy weight method were used to calculate the subjective and objective weights of indicators, the game theory was used to determine the combined weight, and the regret theory was used to evaluate the fire risk level. Based on the theory of WSR, a fire risk assessment index system for an air film stadium was constructed, including four primary and 24 secondary indicators. Based on empirical research, safety management suggestions were proposed. Research has shown that the WSR theory is suitable for constructing a fire risk assessment index system for air-film stadiums. Determine the weight based on game theory to achieve subjective and objective balance. Evaluate risk level based on regret theory, integrating qualitative and quantitative advantages, focusing on objective data and avoiding behavioral preferences. Based on WSR-game weighting-regret theory model, a fire risk assessment was conducted on a certain air film stadium, and the evaluation result was level IV, which is "lower risk", which is in line with the actual situation of the venue.
