Application of Grey Relational Analysis Method in Accidents Analysis of Oil Depots

Aiming at the problem that the precision of quantitative analysis about consequences of oil depot accidents is not high,the grey relational analysis theory was used in semi-quantitative analysis on consequences of the oil tank accident.A mathematical model about grey relational analysis was built.Through scoring cases of depot accident consequences,the sequence of characteristic behavior system was determined.Through comprehensive analysis of evaluation indicators(factors) system about depot security,the sequence of relative behavior system was determined.Through the grey relational analysis,the conclusion matching with reality was obtained.
