An approach to manage human performance related risks in petrochemical sector is to use human reliability analyses (HRA) techniques. However, the focus of HRAs on individuals and on decomposed tasks overlooks the likelihood that collective actions and behaviors might lead to system failures. This study introduces an alternative approach, referred to as Human Performance Integrity (HPI) index, to assess human performance conditions on the whole, as they relate to safety, in petrochemical facilities. Additionally, the approach is used to rate installations in terms of their defenses against safety-relevant human failures. The HPI index is built upon the notions of Cognitive Reliability and Error Analysis Method. By means of a 42-question survey, data was collected on the factors that improve or reduce human performance in 11 oil refineries. Data was used to assess the facilities' safety performance. Results were compared against information obtained from relevant investigation reports, as well as and an independent evaluation of the facilities carried out by certified auditors. Findings support the use of HPI index from novice and experienced scholars and/or practitioners as a quick and effortless, yet sound and efficient manner to assess safety and reliability performance of oil refineries from a human factors perspective.

流程工业人员绩效完整性和可靠性评估的范围界定方法

管理石化行业人员绩效相关风险的一种方法是使用人员可靠性分析 (HRA) 技术。然而，HRA 对个人和分解任务的关注忽略了集体行动和行为可能导致系统故障的可能性。本研究介绍了一种替代方法，称为人类绩效完整性 (HPI) 指数，用于评估石化设施中与安全相关的整体人类绩效状况。此外，该方法用于根据对安全相关的人为故障的防御来对装置进行评级。HPI 指数建立在认知可靠性和错误分析方法的概念之上。通过 42 个问题的调查，收集了 11 家炼油厂改善或降低人类绩效的因素的数据。数据用于评估设施的安全性能。结果与从相关调查报告中获得的信息以及由认证审计师对设施进行的独立评估进行了比较。研究结果支持使用来自新手和有经验的学者和/或从业者的 HPI 指数作为一种快速、轻松、可靠且有效的方式，从人为因素的角度评估炼油厂的安全性和可靠性性能。
