摘　　要：本研究旨在分析层面防护分析(LOPA)在安全完整性水平(SIL)定级中的应用,充分了解LOPA在SIL定级中的重要作用。本文通过定义分析及报告研究,多个角度考虑失效情况,将操作员的人为因素和工艺变化等不确定性因素纳入评估。在实际应用中,LOPA存在一些挑战和限制。其中包括对数据的依赖性、失效概率的评估和不确定性的处理等方面。此外,LOPA需要经验丰富的分析师来进行正确的解释和判断。因此,在使用LOPA进行SIL定级时,合适的培训和专业知识非常重要.本研究揭示了LOPA作为一种有用的工具,在SIL定级中发挥着重要的作用。The purpose of this study was to analyze the application of level protection analysis(LOPA)in safety integrity level(SIL)grading,and fully understand the important role of LOPA in SIL grading.This paper uses definition analysis and report studies to consider failure scenarios from multiple perspectives,including uncertainties such as operator human factors and process changes.In practical applications,LOPA presents some challenges and limitations.It includes the dependence on data,the evaluation of failure probability and the treatment of uncertainty.In addition,LOPA requires experienced analysts to make correct interpretations and judgments.Therefore,proper training and expertise are important when using LOPA for SIL grading.This study reveals LOPA as a useful tool that plays an important role in SIL grading.
