Petrochemical enterprises store and process a large number of flammable, explosive, toxic and harmful chemicals, and their security protection systems are vulnerable. Once damaged by man-made malicious will cause serious losses and adverse effects. Previous studies on the vulnerability of petrochemical enterprises have insufficient consideration of systematicity and uniqueness, and lack consideration of the correlation and game of vulnerability elements. In this study, from the perspective of system, the elements of the security accident system vulnerability are analyzed, and the vulnerability analysis model of security accident system is put forward by studying the interaction between the elements. Threat and exposure constitute the external vulnerability of security accident system, sensitivity and adaptability constitute the internal vulnerability of security accident system; and the threat plays a counter role with sensitivity and adaptability through exposure, which promotes the evolution of vulnerability; Moreover, the different vulnerability elements of security accident system evolve step by step, with the evolution of security accidents. Finally, an illustrative case proves the feasibility of the vulnerability analysis model proposed in this study. The results of this research enrich the theoretical research on vulnerability, provide a reference for the prevention and control of security accidents in petrochemical enterprises.

石化企业安全事故系统脆弱性分析模型研究

石化企业储存、加工大量易燃易爆、有毒有害化学品，安全防护系统脆弱。一旦被人为恶意破坏，就会造成严重的损失和不良影响。以往对石化企业脆弱性的研究对系统性和独特性考虑不够，缺乏对脆弱性要素的关联性和博弈的考虑。本研究从系统的角度分析了安全事故系统脆弱性的构成要素，通过研究要素之间的相互作用，提出了安全事故系统的脆弱性分析模型。威胁和暴露构成安全事故系统的外部脆弱性，敏感性和适应性构成安全事故系统的内部脆弱性；威胁通过暴露与敏感性和适应性起反作用，促进脆弱性的演变；并且，随着安全事故的演进，安全事故系统的不同脆弱性要素也在逐步演进。最后，一个说明性案例证明了本研究提出的脆弱性分析模型的可行性。本研究成果丰富了脆弱性的理论研究，为石化企业安全事故的防控提供了参考。随着安全事故的演进，安全事故系统的不同脆弱性要素逐步演进。最后，一个说明性案例证明了本研究提出的脆弱性分析模型的可行性。本研究成果丰富了脆弱性的理论研究，为石化企业安全事故的防控提供了参考。随着安全事故的演进，安全事故系统的不同脆弱性要素逐步演进。最后，一个说明性案例证明了本研究提出的脆弱性分析模型的可行性。本研究成果丰富了脆弱性的理论研究，为石化企业安全事故的防控提供了参考。
