Abstract

Process Failure Mode and Effects analysis (PFMEA) is a technique to identify, analyze and evaluate the potential failure modes of a production process. The purpose is to suggest control measures to reduce the risk of the production process effectively. NASA has used the PFMEA technique to analyze human processes or tasks. This type of analysis can be referred to as a "human factors process FMEA, HF-FMEA". HF-FMEA breaks down a task process into discrete steps so the actions associated with a process step can be specifically analyzed for potential failure. For each action performed, all potential human errors are identified. Each error is then evaluated to identify positive and negative contributing factors, barriers, and controls. The aim of these works is to give risk reduction measures to minimize the risk of human process. Although HF-PFMEA has achieved significant achievements in the analysis of human factors, the technique itself is still to be improved. For example, the technique has no generic method to decompose the task, and it is difficult to identify human operational errors comprehensively. This paper proposes some solutions to the shortcomings of the conventional approach. Advanced HF-PFMEA integrates several important concepts that distinguish it from conventional HF-FMEA, including: (1) suggest a method to break down task process according to the sequence and logicality of task process, (2) use hazard and operability study (HAZOP) to analyze human operational errors. The operational errors can be identified by determining guidewords and process parameters.
先进的人为因素,过程失效模式和影响分析
过程失效模式和影响分析(PFMEA)是一种识别、分析和评价生产过程潜在失效模式的技术。目的是提出有效降低生产过程风险的控制措施。NASA已经使用PFMEA技术来分析人类的过程或任务。这种类型的分析可以称为“人为因素过程FMEA, HF-FMEA”。HF-FMEA将任务过程分解为离散的步骤,因此与过程步骤相关的动作可以专门分析潜在的故障。对于执行的每个操作,将识别所有潜在的人为错误。然后对每个错误进行评估,以确定积极和消极的促成因素、障碍和控制。这些工作的目的是提供降低风险的措施,以尽量减少人为过程的风险。虽然HF-PFMEA在人因分析方面取得了显著的成果,但技术本身仍有待改进。例如,该技术没有通用的方法来分解任务,并且难以全面识别人为操作错误。针对传统方法的不足,本文提出了一些解决方案。先进的HF-PFMEA集成了与传统的HF-FMEA不同的几个重要概念,包括:(1)根据任务过程的顺序和逻辑性提出一种分解任务过程的方法;(2)使用危害和可操作性研究(HAZOP)来分析人为操作错误。操作误差可以通过确定指导词和工艺参数来识别。
