The importance of safety in high-risk industries such as oil and gas facilities has been reported previously. Process safety performance indicators can provide insight into improving the safety of process industries. This paper aims to rank the process safety indicators (metrics) by Fuzzy Best-Worst Method (FBWM) using the data gathered through a survey.
The study uses a structured approach considering the UK Health and Safety Executive (HSE), the Center for Chemical Process Safety (CCPS), and the IOGP (International Association of Oil and Gas Producers) recommendations and guidelines to generate an aggregate set of indicators. It calculates the level of importance of each indicator based on the opinions of experts from Iran and some Western countries.
The findings of the study demonstrate that some lagging indicators such as the number of times processes do not proceed as planned due to insufficient staff competence and the number of unexpected disruptions of the process due to failure in instrumentation and alarms are important in process industries in both Iran and Western countries. Western experts identified process safety incident severity rate as an important lagging indicator, whereas Iranian experts considered this as relatively unimportant. In addition, leading indicators such as sufficient process safety training and competency, the desired function of instrumentation and alarms, and proper management of fatigue risk play an important role in enhancing the safety performance of process industries. Experts in Iran viewed permit to work as an important leading indicator, while experts in the West focused on fatigue risk management.
The methodology used in the current study gives a good view to managers and safety professionals in regard to the most important indicators of process safety and allows them to focus more on important process safety indicators.
此前已有报道指出安全在石油和天然气设施等高风险行业中的重要性。过程安全绩效指标有助于深入了解如何提高过程工业的安全性。本文旨在通过模糊最佳-最差方法（FBWM），利用通过调查收集的数据对过程安全指标（度量标准）进行排序。
该研究采用结构化方法，参考英国健康与安全执行局（HSE）、化学过程安全中心（CCPS）以及国际石油和天然气生产者协会（IOGP）的建议和指南，生成一套综合指标。它根据伊朗和一些西方国家专家的意见计算每个指标的重要性水平。
研究结果表明，一些滞后指标，如由于员工能力不足导致流程未按计划进行的次数，以及由于仪表和警报故障导致流程意外中断的次数，在伊朗和西方国家的过程工业中都很重要。西方专家将过程安全事故严重率视为重要的滞后指标，而伊朗专家认为该指标相对不重要。此外，领先指标，如充足的过程安全培训和能力、仪表和警报的预期功能以及疲劳风险的妥善管理，在提高过程工业的安全绩效方面发挥着重要作用。伊朗专家将工作许可证视为重要的领先指标，而西方专家则侧重于疲劳风险管理。
本研究中使用的方法为管理人员和安全专业人员提供了有关过程安全最重要指标的清晰视角，使他们能够更加关注重要的过程安全指标。
