基于Dijkstra算法的乡镇消防站选址问题

摘要

在规划时,影响消防站设置的因素很多,最短路径问题是消防站选址的关键内容.主要讨论了基于Dijkstra算法在广大农村辖区内合理的进行乡镇消防站选址的问题,简述了Dijkstra算法在乡镇消防站选址中的应用思路,并通过解决实际问题论证了这种方法的可行性和实用性.在解决实际问题中将各乡镇的交通网络图等效为带权的拓扑结构图,将消防站和各乡镇转化为图上的各个顶点,得出消防站节点到所有节点的最短路径(最短耗时),然后根据实际需要来选择我们所需的路径和节点并建立合理的消防站.该方法为乡镇消防站选址的综合解决方案创造了有利条件,对于广大农村辖区的乡镇消防站选址提供了好的思路.%Many factors may affect the setting of fire station in planning process, and the shortest path problem is a key element of fire station location. The problem of reasonably conducting site choice of township fire station in vast rural area based on Dijkstra algorithm was discussed. The application thinking of Dijkstra algorithm in site choice of township fire station was briefly introduced, and the feasibility and practicality of this method were demonstrated by solving practical problem. When solving the practical problem, the equivalent topology structure graph with weight for transportation network graph of each township was obtained. The fire station and each township were transformed into the vertices in the graph, and the shortest path (the shortest consuming time) from the node of fire station to all nodes was obtained, then the required path and node were selected according to the practical need and the reasonable fire station was established. This method creates favorable conditions for the general solution for site choice of township fire station, and provides good idea for the site choice of township fire station in vast rural area.
