基于文本分析的飞机牵引车作业不安全事件研究

Research on Unsafe Incidents of Aircraft Tactor Operations Based on Text Analysis

为了研究飞机牵引车作业过程的安全性,文章对1989年至2023年间自愿报告系统(ASRS)中12537条涉及飞机牵引车作业不安全事件的叙述和简述部分进行了文本挖掘和文本分析,并结合SHELL模型识别了飞机牵引车作业关键要素,最后采用SHEL-Jaccard系数矩阵对关键要素之间的关系进行分析,提出飞机牵引车作业安全预防和控制措施。研究发现,飞机牵引车作业关键要素如下:以销、刹车、速度控制装置、连接装置、通讯设备为主的硬件要素;以牵引车检查单、机场地面引导线、机场管理为主的软件要素;以牵引车司机、引导、警戒和机组为主的主要人员和以能见度、地面状况、障碍物为主的环境要素。

In order to investigate the safety of aircraft tractors tug operations,this paper conducts text mining and analysis on 12537 narratives and briefs involving unsafe incidents with aircraft tractors in the aviation safety reporting system(ASRS)from 1989 to 2023.By integrating the SHELL model,the paper identifies the key elements of aircraft tractors tug operations.Subsequently,the SHEL-Jaccard coefficient matrix is used to analyze the relationships between these key elements,and measures for the prevention and control of safety in aircraft tractors tug operations are proposed.The study finds that the key elements of aircraft tug operations are as follows:hardware elements mainly consisting of pins,brakes,speed control devices,connectors,and communication equipment;software elements mainly consisting of tug checklists,airport ground guidance lines,and airport management;human elements mainly consisting of tug drivers,guides,guards,and crews;and environmental elements mainly consisting of visibility,ground conditions,and obstacles.
