基于主成分分析法的石化码头装卸过程安全评价

Safety Evaluation on Handling Process of Petrochemical Wharf Based on Principal Component Analysis

采用主成分分析法(PCA)筛选出对石化码头装卸过程安全有较大影响的主要指标,并结合统计软件SPSS计算出不同石化码头装卸过程安全水平的综合评价值,得到不同码头的安全状况。实证结果表明,用PCA对石化码头装卸过程安全评价是可行的,评价过程避免了主观随意性,且评价结果与实际情况一致。

The principal component analysis is applied to select the main indexes largely influencing petrochemical wharf handling process ,also with the help of SPSS （Statistical Program for Social Sciences ） ,the comprehensive evaluation values of handling process safety level for different petrochemical wharfs are calculated and the safety conditions of different wharfs have been obtained .The application shows that it is feasible to evaluate the handling process of petrochemical wharf safety with PCA ,which can avoid subjective random and also the evaluated result conforms to the actual situation .
