人为因素是影响设施安全运行的重要因素。人为因素包括系统地应用有关人的特征和行为的信息，以提高过程系统的安全性。很大一部分人为错误发生在维护阶段。然而，在维护阶段的人为错误概率的量化还没有得到应有的重视。本文着重对水泵维修前后的人为因素进行了分析。对于可能出现的故障情况，应考虑将工艺设备从服务中移除（维修前）和将设备返回服务（维修后）的程序。对于每个场景，使用成功可能性指数方法（SLIM）计算每个活动的人为错误概率。这种方法也评估了后果。对每个组成部分进行风险评估，并通过添加单个风险来估计总体风险。本研究旨在强调在定量风险分析中考虑人为错误的重要性。所开发的方法已应用于海上加工设施的案例研究。(C) 2013 Elsevier Ltd.版权所有。
Human factors play an important role in the safe operation of a facility. Human factors include the systematic application of information about human characteristics and behavior to increase the safety of a process system. A significant proportion of human errors occur during the maintenance phase. However, the quantification of human error probabilities in the maintenance phase has not been given the amount of attention it deserves. This paper focuses on a human factors analysis in pre-and post-pump maintenance operations. The procedures for removing process equipment from service (pre-maintenance) and returning the equipment to service (post-maintenance) are considered for possible failure scenarios. For each scenario, human error probability is calculated for each activity using the Success Likelihood Index Method (SLIM). Consequences are also assessed in this methodology. The risk assessment is conducted for each component and the overall risk is estimated by adding individual risks. The present study is aimed at highlighting the importance of considering human error in quantitative risk analyses. The developed methodology has been applied to a case study of an offshore process facility. (C) 2013 Elsevier Ltd. All rights reserved.
