| 摘 要： | 为深入研究石化企业员工面对突发事故时人因失误概率(HEP)的变化情况,基于系统动力学(SD)理论和方法,构建事故下企业员工HEP的因果图和系统图,并运用Vensim软件进行动态模拟,定量分析各因素对企业员工HEP影响的动态演化过程。结果表明:HEP曲线变化以35 h为截止点被划分为2个特征不同的阶段,截止点之前及之后的主要影响因素分别是风险认知和个人安全承诺,调整HEP影响因素的人因误差效应指数能改变HEP的演化趋势。

| Abstract: | In order to deeply study the changes in HEP of petrochemical employees in the face of accidents,based on SD theory and method,a causal map and a system map were drawn for enterprise employees HEP under accidents. Dynamic simulations were performed by using Vensim software to quantitatively analyze the dynamic evolution process of the influence of various factors on corporate employees’ HEP. The results show that the change in HEP curve is divided into two different stages with 35 h as the cut-off point,that the main influencing factors before and after the cut-off point are risk cognition and personal safety commitment,and that the trend in the evolution of HEP can be changed by controlling the changes in different HEP influencing factors. |
