| People's life and social environment is influenced by the high frequency and deadly results of Petrol-chemical Industry fire seriously. It is not a new task for the hidden trouble analysis of Petrol-chemical Industry,but with the development of science and technology,several new arts and crafts and materials and equipments are introduced into the petrol-chemical industry。So,the benefits and the risk are brought at the same time. It is significant for people to evaluate the risk of Petrol-chemical industry with modern methods.The fire fatalness of production process which based on different kinds of chemistry reaction is analyzed entirely on the base of the analysis of architecture construction and equipments and production arts and crafts etc. The results of craftwork equipment and oilcan fire etc are confirmed through fire stat of Petrol-chemical Industry.The trait of different safety assessment methods and applicability are analyzed by this paper. Gray analytic hierarchy process isGray analytic hierarchy process is combined by analytic hierarchy process and the whitening of interval gray number, gray number judge matrix is constructed and whitened, the error is avoided which is brought by the uncertainty in the progress of cognizing information. With the supplement of interval gray number, analytic hierarchy process is more impersonality in the analysis of fire risk in petrol-chemical industry.The combining and application of gray theory and analytic hierarchy process in the safety evaluation in Petrol-chemical Industry is the important breakthrough. |
