基于HEART方法的救生舱供氧系统操作可靠性分析

Research on operational reliability of oxygen supply system in refuge chamber based on HEART method

利用HEART方法对救生舱供氧系统的任务分类和差错诱发条件进行分解,提高了该方法在手动控制系统操作可靠性分析领域的适用性,可以对救生舱供氧系统操作中的人因失误概率和人的操作可靠性进行定量分析,并发现影响人的操作可靠性的差错诱发条件,可为救生舱管理单位制定管理措施和人员培训方案提供理论依据。

The paper applied the HEART method to decompose the task classification and error producing conditions of the oxygen supply system in the refuge chamber, and improved the applicability of the method in the operational reliability analysis field of manual control system. And then, it conducted quantitative analysis on human error probability and human operational reliability during operation of the oxygen supply system in the refuge chamber, and found out the error producing conditions affecting the human operation reliability. The results offered theoretical reference for constitution of management measures and staff training plan in refuge chamber management department.
