世界航运网络复杂性分析

Analysis of complexity in global shipping network

航运系统可以抽象为由港口和航线构成的网络,这个网络的结构与几何性质对港口与航线的规划和管理具有重要的影响.在对复杂网络的形成、特性和代表性研究成果简要总结的基础上,对马士基航运集团下属的航运网络进行了实证分析,研究了国际航运网络表现出的小世界与无标度特性,并对其具有的一些不符合典型复杂网络统计特性的现象进行了分析.可为今后政府和企业的航运线路、港口建设规划及管理提供科学的研究手段和理论支持.

Shipping system can be defined abstractly as a network composed of ports and sea routes. The structure and the geometric characteristics of the network have important effects on the layout and management of ports and sea routes. Based on the brief summarization of the development, properties and representative research achievements of complex networks, an empirical analysis in Maersk-Sealand group＇s global sea routes network is made. It focuses on the small-world effect, scale-free properties, analyzing the reasons accounting for some individuality of the network. The research is designed to provide the government and shipping enterprises with scientific research methods and theoretical support for the management of the ports and the programming of sea routes in the future.
