摘　　要：基于复杂网络理论,定义集装箱海运网络的稳定鲁棒性和性能鲁棒性,通过数值模拟,计算网络的度分布、簇系数、平均路径长度等指标,并研究集装箱海运网络在随机和蓄意两种攻击方式下的鲁棒性表现。研究结果表明,集装箱海运网络虽体现一些无标度特性,但仍以随机性为主;鲁棒性较好,且遵循一定的变化规律。本研究为集装箱海运系统能够稳定持续运行提供理论依据,也对提高网络的抗干扰能力、增强其鲁棒性提出研究思路。Using the perspective of complex network to define the robustness of container marine transport, calculates the elements of degree distribution,clustering coefficient, average path length,and analyzes the robustness of the network under random attacks and selective attacks through numerical simulation. The simulation results indicate that the container marine transport system has some scale-free characteristics but it remaines the randomness,and possesses a better robustness which followes some statistical rules. This reseaeh provides the theoretical basis for continuous stable operation of the system and puts forward the research approaeh for the study of the robustness of container marine transport.
