基于复杂网络理论的地铁运行干扰源分析
Analysis of metro operation disturbances based on complex network theory
摘要
Abstract
To enhance the safety level of metro operation,26 disruptive events are identified through the metro accidents and risk checklists.The interrelations among the disruptive events are clarified by the employing event chain,and the metro operation disturbance network (MODN) is established.Then,the complex network theory (CNT) is utilized to explore the characteristics of metro opera tion disturbances by revealing the topological properties of the MODN.Finally,four immunization strategies are put forward to enhance the system safety based on the target immunization theory,and the effects of these strategies are evaluated.The results indicate that it is feasible to study the nature of metro disturbances by the CNT.The MODN is a complex network with small-world property and scale-free property,in which the disturbances can spread easily.With regard to the immunization strategies,the immune effect of the selective immunization strategy is better than that of the random immunization strategy.Concerning the selective immunization strategies,the immune effect of the strategy based on degree and between centrality is better.The interference sources with high betweenness and high degree of interference should be emphasized during metro operation.关键词
