【摘要】：为了分析在我国目前的政策、技术等环境水平下甩挂运输系统的安全水平,在分析其发展风险因素的基础上,将甩挂运输系统划分为子系统。建立了各子系统与系统安全水平之间的因果关系模型,并分析了因果反馈环。绘制了系统动力学流图,并进行了仿真分析。结果表明:甩挂运输系统安全水平2013年为81.673 7,2015年为89.461 3,等级为良。这说明随着运输组织调度能力、安全技术水平的提高和政策环境的改善,系统安全水平偏低但会不断提高,在发展初期需要加强安全管理。通过子系统的灵敏性分析发现:甩挂运输政策环境和甩挂车辆安全技术水平是对系统安全水平影响较大的因素,因此应尽快完善相关政策法规,并提高对甩挂车辆的安全投入,以促进甩挂运输的安全、快速发展。
[Abstract]:In order to analyze the safety level of the transportation system under the current policy, technology and other environmental levels in our country, and on the basis of analyzing the risk factors of its development, The transportation system is divided into subsystems, the causality model between each subsystem and the safety level of the system is established, the causal feedback loop is analyzed, and the system dynamic flow diagram is drawn. The simulation results show that the safety level of the transportation system is 81.673 7 in 2013 and 89.4613 in 2015. This indicates that with the improvement of transportation organization and dispatching ability, the safety technology level and the policy environment are improved. The security level of the system is low but will continue to improve. In the early stage of development, it is necessary to strengthen the safety management. Through the sensitivity analysis of the subsystem, it is found that the transportation policy environment and the safety technical level of the dump and hang vehicle are the factors that have a great influence on the safety level of the system, so we should improve the relevant policies and regulations as soon as possible. In order to promote the safety and rapid development of swing-and-hang transportation, the safety investment of swing and hang-up vehicles is improved.
