President Xi Jinping raised the initiative of jointly building the 21st-Century Maritime Silk Road in October of 2013.Then the relevant government departments jointly issued the "Vision and Actions".The announcement aims to promote the connectivity of Asian,European and African continents and their adjacent seas.It is inseparable from the development of container transportation.Container shipping network is necessary for container transportation,has very important research value.The network is a load network,has a lot of logistics,information and capital,has the characteristics of openness,dynamic and relevance.Once the network occurs earthquakes,tsunamis,strikes,war and other incidents,it is very likely that the impact of the incident will be spread and cause huge economic losses.Container shipping network determines the connectivity of 21st-Century Maritime Silk Road and requires strong invulnerability.How to study the impact of cascading failure on invulnerability of container shipping network and enhance it becomes an urgent problem.Firstly,this paper introduces the theory of container shipping network,invulnerability and cascading failure;Secondly,the paper analyzes the development of container transportation of 21st-Century Maritime Silk Road,builds the topological structure of the container shipping network,analyzes the network and evaluates it’s invulnerability.Thirdly,the paper describes the process of cascading failure on container shipping network,builds the cascading failure model combined with the characteristics of container transportation,and designs the study project based on the model.Finally,the paper studies the invulnerability of the container shipping network.The study shows that the container shipping network of 21st-Century Maritime Silk Road has the worst invulnerability under the maximum load failure and can improve the invulnerability by the nonlinear relationship between capacity and initial load,residual capacity allocation or adding edge.Besides based on the research,the paper puts forward the measures to improve the invulnerability of the container shipping network of 21st-Century Maritime Silk Road from two aspects of prevention and remedy. |
