Connectivity Reliabilitsy of Container Shipping Network of the 21st Century Maritime Silk Road

A container shipping network of the 21st Century Maritime Silk Road is mainly composed of four heading networks: Southeast Asia, South Asia, Middle East-North Africa and Europe. In this paper, a connectivity reliability simulation model is set up when the ports along the route are under random attack by using the simulation method, and the reachable matrix is introduced to judge the variation of the connectivity reliability of the shipping network and the four heading networks. The container shipping network of the 21st Century Maritime Silk Road was relatively reliable. Among its four heading networks, the connectivity reliability of European heading was relatively poor, and that of Southeast Asia was relatively good. In addition, using qualitative and quantitative methods to judge the node importance and implement the key node protection strategy for re-simulation, it can be gotten that the key node protection strategy is effective to improve the connectivity reliability of the whole network and each heading network.
