Reliability assessment and identification of key passages of the railway transportation network in Shanxi-Shaanxi-Inner Mongolia energy-rich region
摘要
Abstract
Railways play an irreplaceable role in the long-distance transportation of bulk energy materials such as coal.In the context of uncertainty becoming the new normal in transportation operations,it has far-reaching strategic significance of exploring the reliability of railway transportation networks in energy-rich regions to enhance the resilience of railway transportation networks and ensure national energy security.On the basis,the railway network in Shanxi-Shaanxi-Inner Mongolia energy-rich region,one of China's most important energy and chemical bases,is selected as the research object.A railway network model of Shanxi-Shaanxi-Inner Mongolia energy-rich region is constructed by using the Space-L method,the reliability of the railway transportation network is analyzed systematically by using two attack strategies:random attack and deliberate attack,and key transportation corridors are identified.The research results indicate that the railway network in Shanxi-Shaanxi-Inner Mongolia energy-rich region is relatively sparse and exhibits scale-free network characteristics.Small-scale random attacks render the network more reliable,while the network becomes more robust under high-betweenness attacks but exhibits vulnerability under high-degree attacks.Under different attack strategies,the cumulative effect of multiple node failures leads to a phased and sharp decline in network performance.The key corridors of the railway network in Shanxi-Shaanxi-Inner Mongolia energy-rich region are highly concentrated in small areas,mainly located at the intersections of coal transportation dedicated lines and external transportation railways.In future energy transportation planning,efforts of protecting these key corridors must be strengthened to ensure their continuous and stable operation,maintaining the safe operation of the energy transportation network.关键词
