铁路应急管理是铁路运营管理的重要内容。Voronoi图和Delaunay三角网是对偶图,在地理信息系统、计算机网络中有许多实际应用,在铁路应急管理中也可以发挥作用。本文首先介绍Voronoi图和Delaunay三角网,然后介绍其在铁路应急物资调运、突发事件影响分析方面的运用,最后指出Voronoi图和Delaunay三角网新的研究成果在铁路应急管理中的运用需要进一步研究。
Railway emergency management is an important part of railway operation and management. Voronoi diagram and Delaunay triangulation are dual graphs. They have many practical applications in GIS and computer network and can also play a role in railway emergency management. This paper firstly introduces the Voronoi diagram and Delaunay triangulation, and then introduces its application in the railway emergency materials dispatching and emergency impact analysis. Finally, it is pointed out that the application of Voronoi diagram and Delaunay triangulation should be further studied in the emergency management of railway .
