A Petrochemical Process Safety Risk Assessment Method Based on Improved Principal Component Analysis

石油化工工艺易受到外界因素的影响,难以准确识别其风险状态。为此,文章设计了一种基于改进主成分分析法的石油化工工艺安全风险评估方法。该方法分析了多种安全风险评估因素,包括人为操作、设备状态、技术先进性、管理策略和外部环境等。通过采用基于改进主成分分析法的计算方法,对这些因素进行量化分析,并得出了各自的安全风险权重,从而明确了各因素在整体安全风险中的贡献程度。在此基础上,构建了石油化工工艺的安全风险评估模型。该模型能够综合考虑各种因素之间的相互作用,并通过模型计算确定石油化工工艺的安全风险评估等级。实验结果表明,文章设计的基于改进主成分分析法的石油化工工艺安全风险评估方法,安全风险评估平均分数达到了83.33,这表明该设计方法在安全风险评估上更为准确,能够更有效地识别和管理风险。

Petrochemical processes are affected by complex and interacting factors,making it a great challenge to accurately identify their risk status.This paper designed a safety risk assessment method based on improved principal component analysis.This method analyzes a variety of security risk assessment factors,including human operation,equipment status,advanced technology,management strategy and external environment.By adopting the calculation method based on improved principal component analysis,these factors are quantified and their respective safety risk weights are obtained,so that the contribution of each factor in the overall safety risk is clarified.On this basis,the safety risk assessment model of petrochemical process is constructed.The model can consider the interaction of various factors and determine the safety risk assessment level of petrochemical process through model calculation.The experimental results show that the safety risk assessment method of petrochemical process designed in this paper based on improved principal component analysis has an average score of 83.33,which shows that the design method is more accurate in safety risk assessment and can identify and manage risks more effectively.
