Explosive Risk Evaluation of LPG Tank under Fire Based on Comprehensive Evaluation Algorithm

Abstract

Abstract. The explosive risk evaluation of LPG tank under fire is important for putting forward the safety measurement, in order to improve the evaluation correctness, and the fisher fishing algorithm and the grey relational analysis are applied in it. Firstly, the explosion characteristics of LPG tank under fire are discussed. Secondly, the basic theory of fisher fishing algorithm and grey relational analysis are studied. Thirdly, explosive risk evaluation simulation of LPG tank under fire are carried out based on the comprehensive algorithm, and results show that new evaluation method can evaluate the explosive risk of LPG under fire effectively.
