摘要

The security ot transportation network has an important effect on the efficiency of emergency logistics. It isnot only relevant to the topological structure of networks,but also to the ways that attack networks. Thepaper,based on complex network theory and graph theory,analyzed the effect on the security of transportationnetwork of emergency logistics respectively caused by cut vertex attacks,cut edge attacks and avalanche attackswith following conclusions. Firstly,there is a worse breakage for homogeneous transportation network (likenetworks of railway,highway and waterway) than for inhomogeneous ones (like network of airway) caused bycut edge attacks. Secondly,there is little difference among different types of networks in security whenattacked by cut vertex attacks at random. Thirdly,cut vertex attacks' effect on the security of inhomogeneoustransportation networks is bigger than that on homogeneous ones. Forth,to avalanche attacks,there arecritical thresholds for security in all kinds of networks,but the security of inhomogeneous transportationnetworks is worse than that of homogeneous ones.
