结合Bow-tie和HFACS的特点及事故链理论建立分析模型,根据分析模型从危险源、可能性和严重度三个角度分析了不同来源的安全信息特征,得出了使用不安全信息无法实施风险分析的原因。通过实例验证了本文研究的结论,该成果可以帮助指导更好地利用安全信息开展风险分析,建立以安全信息为驱动的安全管理机制。
According to the characteristics of Bow-tie and HFACS and accident chain theory, the analysis model is established. According to the analysis model, the characteristics of safety information from different sources are analyzed from the perspectives of danger source, possibility and severity. The conclusion is that risk can not be implemented using unsafe information Analysis of the reasons. An example is used to verify the conclusion of this paper, which can help guide the better use of safety information to conduct risk analysis and establish a safety management mechanism driven by safety information.
