| 摘 要： | 城市公共设施选址既要充分体现该设施的利用价值,又要减少和避免由于各设施的重复覆盖而造成的资源浪费.为此首先对普通Voronoi图和加权Voronoi图进行了介绍,然后利用层次分析法解决了拥有综合多因素影响的加权Voronoi图的权值确定问题.一般一个平面图形的重心通常被认为是该区域的平衡位置.所以对于每个公共设施的影响区域进行基于综合因素的加权Voronoi区域划分后只要确定出这个区域的重心位置即可确定该公共设施的最佳选址位置.

| Abstract: | In the process of site selection,we hope not only to realize the value of the facility,but also to reduce and avoid duplication of facilities due to the coverage of the resulting waste of resources.There fore,we first introduced the ordinary Voronoi diagram and the weighted Voronoi diagram,then we achieved the two voronoi diagram with discrete method.By using analytic hierarchy process,we determine the power value which the weighted Voronoi diagram has a comprehensive affect factors.A center of gravity of t... |
