标题：Study on safety evaluation of hazardous chemicals transportation industry in Capital city based on principal component analysis and cluster analysis
摘要：With the reform of chemical transportation industry accelerating, the safety evaluation of chemical transportation industry in China is becoming more and more standardized. Based on the theory of big data analysis and SPSS software as a platform, first of all, of the Beijing 91 the system construction and management of dangerous chemicals transportation enterprises, safety culture, safety production standardization 24 safety evaluation indexes such as principal component analysis, it is concluded that safety training basic requirements, loading and unloading operation, parking lot, civil air defense, vehicle dynamic supervision, system construction and management, safety production standardization, pilot eight kinds of factors as the main indexes for safety assessment. After using the eight indexes of 91 clustering analysis for transport enterprises, the enterprise is divided into five clusters of reasonable results, through the summary of common characteristics within the same cluster enterprises, it is concluded that the handling operation index plays an important role in classification for transport enterprises such as conclusion, can provide reference for other areas. At the same time, the conclusion can be used as a reference for the follow-up safety evaluation of hazardous chemical transportation enterprises, so as to achieve the purpose of targeted safety inspection.
