基于加权Voronoi图的民航机场空间服务范围研究

Service Coverage of Civil Aviation Airports Based on Weighted Voronoi Diagram

民航机场空间服务范围的合理确定是机场经营管理中遇到的重要问题之一.针对目前按照行政区域界定民航机场空间服务范围的不科学性,本文分析了影响机场服务范围的因素,引入加权Voronoi图,分析了其在机场空间服务范围划分问题上应用的科学性和可行性,结合广东省区域的机场现状进行了研究,分析显示加权Voronoi图在机场空间服务范围划分问题上具有较好的效果,能够解决相邻多个民航机场之间空间服务范围划分问题.研究表明,应用加权Voronoi图可以合理界定机场的空间服务范围,该方法比基于行政区域界定机场空间服务范围的方法更加符合民航市场的客观情况.

Determining reasonable service coverage of an airport is one of the important prerequisite for airports management. Aiming at the common unscientific approach of delimitating airports service coverage based on administrative division, this paper analyzes the factors which restricts the area of an airport influence and then introduces the principles of weighted Voronoi diagram. It also examines the feasibility of its applying to delimitate airports service coverage. In the last section, the paper provides an example to illustrate the solving of the problem. It is found that the approach of delimitating airports service coverage based on weighted Voronoi diagram is more suitable for the objective situation of civil aviation market than that based on administrative division.
