校验压力表系统故障人因分析的HRA事件树

HRA Event Tree of Personnel Factor Analysis for Pressure Gauge Check System Breakdown

利用人员可靠性分析事件树的理论方法，树立了事件树分析与人员可靠性分析的基本概念，阐明了人员可靠性分析中应力与行为形成因子的特性．确定了压力表系统ＨＲＡ事件树形成前的任务和约定，建立了校验压力表系统故障人因分析的ＨＲＡ事件树，叙述了建造过程．分析了操作人员不同操作形态可能的行为结果，计算了人员操作失误的系统可靠度。

The HRA event tree of personnel factors analysis for pressure gauge check system breakdown is built up utilizing a theoretical method of personnel reliability analysis event tree, the possible behavior results of operating personnel with different operating formation are analyzed, and the system reliablity of personnel operation faults is calculated. Finally, the influence degree of personnel reliablity analysis in engineering research are quantitatively illustrated.
