based on the data structure of the link-edge-node combined structure mine geographic network model, a shortest path improved algorithm was provided.
基于链-边-节点联合结构矿井地理网络模型的数据结构,提出了最短路径的改进算法。
the results showed that the algorithm would have the features suitable to the mine geographic network and the advantage of high calculation efficiency.
结果表明,该算法具有适应矿井地理网络特点,运算效率高的优点。
a center's service area of a geographic network is broadly applied in practical life. in traditional method, it is expressed by an isochronous area or an equidistance area.
地理网络的中心服务范围在实际生活中应用广泛,传统方法一般用等时区或等距区表示。
one of ways is that the stations are viewed as 「nodes」 and rails are regarded as 「links」, thus a railway geographic network is generated.
一种是以铁路的站点作为「节点」,并以轨道作为「边」,这样生成的网络称为铁路地理网。
study the basic model and algorithms of the geographic network analysis.
分析研究几类基本的地理网络分析算法。
based on the achievements above, the experimental system for geographic network analysis the on pc platform is developed.
基于前面的研究从底层开发了一套实验型地理网络分析系统。
the geographic network analysis is the main method for the research of the spatial location-relation and the spatial correlation.
