| Abstract: | Delimitating economic object's affacted
coverage is very difficult, but it is very important to urban planning and regional
planning. In practice, we often define the administrative division or geographical unit of
an economic object as its influential area, and this has its deficiency. This paper
presents a new promising method which uses Voronoi diagram for solving it. It firstly
introduces the principles of ordinary Voronoi diagram and generalized Voronoi diagram,
then writes the corresponding program , lastly makes the application of Voronoi diagram in
designating the influenced boundary of the economic object. |
