摘要
船舶交通流受到多种因素的影响,难以用精确的数学模型描述,人们常用仿真的方法对其进行研究。通过仿真,可以定量或形象地分析船舶的行为特征和规律,评价航道的通过能力、航行风险、组织和管理等能力。对国内外船舶交通流建模和仿真的进展情况进行分析和总结,回顾了船舶交通流仿真的国内外研究现状,提炼了交通流仿真的核心内容和流程。同时探讨了船舶交通流的建模方法,并分析了船舶交通流仿真的关键技术及典型应用。最后展望了交通流仿真的发展趋势。
The vessel traffic flow is affected by many factors and it is difficult to describe it with an accurate mathematic model. So it is studied by means of simulation in order to analyze quantitatively or visually the behavior characteristics and laws of vessels and to evaluate the transit capacity of channels,navigation risk,organization and management ability and so on. In this paper,a review is made on the modeling and simulation of the vessel traffic flow. Firstly the research status of simulating the vessel traffic flow is introduced; secondly its core content and process are refined; thirdly its modeling methods are discussed; fourthly its key technologies are analyzed; fifthly its main applications are summed up and finally its development trends are presented. Simulation modeling theory and method as well as implementation technology for the vessel traffic flow are not mature,and there are many problems to be solved. The domestic research lags behind that of foreign countries,therefore it is necessary to promote the relevant research to provide technical support to the development of a green,safe and efficient maritime traffic.
