Research On Reliability Of Countrywide Railway Network Based On Theory Of Complex Network

Railway transportation has a very crucial position in our continent country because of its large capacity, low cost and consuming which ascertains its station in freightage and passenger transport of long and secondary distance. According to improving railway transportation, it posed higher demand to the reliability and adaptability of railway network.It has theoretical importance and practical significance to evaluate reliability of railway transportation network which based on the theory of complex network. It can identify the key hub of railway network, which also can arouse attention to the fault of railway network .More important, it can prevent intrusion and damage to railway network and can explore the potential reliability, service and attraction of railway network.The structure of railway network has important influence to the connectivity reliability of railway network. Therefore, we analysis the demographic characteristics of railway network from the perspective of complex network, and then give a definition of connectivity reliability of it which based on two different modes of attack .Finally, we give an example of countrywide railway transportation network, we gain its change disciplinarian under different attack according to reliability evaluating guideline .
