摘要: 为识别危险品道路运输系统中的风险因素,从源头上预防运输事故发生,应用N-K模型分析系统耦合风险。首先将风险因素划分为人、机、物、环、管5类;其次根据参与耦合的风险因素数量划分出单、双、3、4和5因素耦合风险;然后采用N-K模型计算各种耦合的耦合风险值;最后以我国2017年上半年发生的220起道路危险品运输事故为例,计算系统耦合风险。结果表明:参与耦合的风险因素越多,耦合风险值越大;人-环耦合风险最大;物-管耦合风险最小;主客观相互耦合风险较大;多种主观因素耦合风险较小。

Abstract: In order to identify risk factors in road transportation system of dangerous goods and prevent transportation accidents from the source, the N-K model was used to analyze the system risk coupling. Firstly, risk factors were divided into five categories: human, machine, material, environment and management. Then according to the number of risk factors involved in the coupling, single, double, triple, quadruple and five factors coupling risks were divided, and the N-K model was used to calculate the coupling risk values of various couplings. Finally, taking 220 road dangerous goods transportation accidents in China in the first half year of 2017 as examples, the system coupling risk was calculated. The results show that the more risk factors involved in coupling, the greater the coupling risk value will be, that the risk of coupling between human and environment is the greatest and that between material and management is the smallest, and that coupling risk between subject and objective is relatively large while the risk of multiple subjective factors coupling with each other is smaller.
