摘　　要：为研究区域内船舶行为对交通状况的影响,研究了基于复杂网络的关键船舶识别方法。将水域中的船舶看作为复杂网络中的节点,根据船舶间的行为交互关系构建区域面向船舶行为分析的复杂网络;并结合复杂网络的节点中心性指标构建节点综合重要度评价模型;通过节点综合重要度评估结果,对网络中的节点进行节点重要度排序,识别网络中的关键节点。对比度节点中心性识别关键节点方法,实验结果表明,2种方法的分析结果中节点排序结果相同的节点数占节点总数的比例达到77.8%,但节点综合重要度评价方法对各指标进行权重配比,充分考虑了各指标对关键节点识别结果的影响,能有效识别区域关键船舶。To study impacts of ship behavior on traffic conditions in one area,a key ship identification method based on complex network is studied.In this method,ships in the area are regarded as nodes in a complex network,and the re⁃gional complex network for ship behavior analysis is constructed according to behavior interaction between ships.Com⁃bined with complex network centricity index,an evaluation model of comprehensive importance of nodes is developed.The critical nodes in the network are identified by ranking their node importance based on the evaluation results.Com⁃pare with the centricity identify key nodes method,the results show that the number of nodes with the same node ranking in the analysis of the two methods have the same proportion of 77.8%of the total number of nodes.However,the evalua⁃tion method of comprehensive importance of nodes carries out weight ratio for each index,and the influences of each in⁃dex on the identification results of key nodes is fully considered,which can effectively identify key ships in the region.
