高铁轨道设备K-SIGMA模式安全风险评估

Safety Evaluation on K-SIGMA Mode of HSR Track Devices

为定量分析影响高铁轨道设备安全的单个风险因素,基于K-SIGMA模式,考虑轨道设备单个风险因素的7方面属性指标,采用随机赋权法确定指标权重,并从风险梯度、风险强度以及风险水平3方面对高铁轨道设备安全风险因素进行评判。研究结果表明,运用该方法对高铁轨道设备单因素进行风险评估,具有较强的可行性,可为风险管理者制定合理的控制措施提供参考。

To quantify the influence of one single risk factor on HSR track devices, the paper - building on K-SIGMA mode - considers the seven attribute indicators of each factor and brings in the random weighting method to determine the weight of each indicator. It then evaluates the risk factors from three aspects risk gradients, risk intensity and risk level. The results show that single-factor risk evaluation on HSR track devices is highly applicable, as it provides references tbr risk managers to map out an appropriate scheme lbr risk control.
