大型游乐设施事故原因的帕累托图分析

Cause Analysis of Large-Scale Recreational Facilities Accidents Based on Pareto Chart

摘要: 为查明大型游乐设施事故发生的主要原因，精准采取相应措施减少事故发生，应用管理学上的帕累托法则，对2007~2016年间观览车类、滑行车类、飞行塔类等三大类大型游乐设施的事故原因进行了统计分析。结果表明，导致大型游乐设施事故发生的主要原因是设备疲劳断裂、电路故障、设备自动运行，次要原因是安全保护装置失灵、安全管理不到位、制动系统故障、游客行为不规范、工作人员违章作业等。研究结果便于厘清事故原因主次，集中资源消除事故隐患。

Abstract: In order to find out the main cause of the accident of the large amusement facility and take corresponding measures to reduce the accidents, the law of Pareto chart was used to analyze the cause of the accident in the three categories of the large-sized recreational facilities for years 2007-2016 in the paper. The results show that the key causes of Large-scale Recreational Facilities were fatigue fracture, circuit fault and automatic operation of equipment; and secondary causes were invalid safety protection device, farfetched safety management, brake system fault, tourists behavior, illegal operations of staff, and so on. The research results can help clarify the main reason and subordinate reason of the accident, so as to centralize the resource for accidents elimination.
