2种地铁司机轮班疲劳评价方法的比较

A comparison between two methods of evaluating shift subway drivers fatigue

为减少轮班制度下地铁司机的疲劳风险,基于司机轮班疲劳的5个评价指标,研究适用于轮班疲劳评价的池田公式和疲劳指数(FI)等2种方法。对比2种方法的理论基础及计算模型,并运用这2种方法计算北京燕房线地铁司机的轮班疲劳度。结果表明:2种方法在评估地铁司机单班疲劳时给出的结果存在明显差异,在评估周期轮班疲劳时结果显著相关;用池田公式可精确评定轮班表中的每项工作引起的疲劳,用FI法评价长时间轮班疲劳时更为简单便捷。

For the sake of reducing shift subway divers fatigue risk,the paper introduces and makes a comparison between two fatigue risk evaluation methods,the Ikeda method and the fatigue index method,and analyzes 5 factors leading to driver’s fatigue.The paper compares the principles and formulas of these two methods and uses them to evaluate shift drivers fatigue level of the Beijing Subway Yanfang line.The calculation results show that for a single shift,the fatigue level obtained by using the Ikeda method differs significantly from that by using the fatigue index method,but for periodic shifts,there is no striking difference between the levels obtained by using the two,that the Ikeda method can accurately evaluate fatigue caused by each work in the shift table,and the fatigue index method is a more suitable method of evaluating fatigue caused by the long shift.
