Survivability Analysis Of Dangerous Goods Transport Network Based On The Complex Network

Road net is one of the vital medias for economy operation, the stability of it has a direct impact on national economy development and human’s daily life. Moreover, the requirement and transport volume of dangerous goods increase significantly, those time-bomb-like dangerous goods transported in the road net once targeted by the terrorists will cause a huge damage. Therefore, researching the anti-destroying ability of dangerous goods transport network scientifically and objectively to further perfect and improve the ability of national security is extremely important. In recent years, the rise and development of the research on complex networks at home and abroad provide a new thought to analysis the regional dangerous goods transport network.Based on regional dangerous goods transportation network as the research object, this paper firstly reviewed the research status at home and abroad based on the theory of complex network, described the basic theory of complex network and the simulation software MATLAB. Then studied the model building method of regional dangerous goods transport complex network and a network topology map was established based on Arcgis software. The analysis of the basic characteristic parameters such as network degree, average shortest path length and clustering coefficient (betweenness) determined the network type of the regional dangerous goods transportation network. Choosing appropriate anti-destroying ability evaluation indicator---the entire network performance and comparing various attack strategy to simulate the Mutilate of regional dangerous goods transportation with weighted and un-weighed network, and studied the optimal mutilate strategy and damage characteristics with the simulation result. At the end of the paper, research conclusion put forward to the deficiency of the proposed model.The research of this paper focus on the following two aspects:one is the complex network theory researches are mainly concentrated in the field of communications and computer, and the researches in traffic and transportation also cover more in railway, aviation and other fields, but lack of studies in regional dangerous goods transport system; second is the simulation experiments, this paper covered the random attack and point-and-line attacks based on degree, betweenness and weights, and then analyzed the anti-destroying ability of regional dangerous goods transport network comprehensively, the damage threshold and the optimal mutilate strategy of this network are concluded in various attack strategies.
