摘要: 针对城镇应急资源配送速度慢与交通组织通达性不通畅的问题,以暴雨灾害为背景,提出一种城镇应急资源储备点快速选取和布局优化的方法。该方法以武汉市洪山区为实例,首先从确定的暴雨灾害影响下应急资源储备点选址的6个基本条件中筛选出研究区域中8个合适的应急资源储备点;然后运用弗洛依德算法计算由储备点出发的配送路径,以总路径距离最短为目标,得到这8个储备点当个数不同时其位置分布的关系。分析表明:增加储备点个数会减少配送路径总长度并提高配送效率,但当储备点超过5个后,增加储备点个数的意义已不明显,5是该区域的最佳储备点个数;该结论也适用于其他城市背景。

Abstract: In view of problems of urban emergency resource distribution, such as slow speeds and traffic organizational obstruction, this paper takes rainstorm disaster as background, and works out a methodology of siting of urban emergency resources depots and layout optimization. The methodology is worked out on the basis of Hongshan District of Wuhan as an example and involves establishment of an evaluation index system, siting of alternative emergency resources depots, calculating total length of distribution routes for the depots by using the Floyd-Warshall algorithm, and studying the relationship between the number of depots and the total length. The results show that increasing number of depots can reduce the total length of the distribution path and improve the distribution efficiency, however, when the number of depots in this area is more than five, it has no apparent effect on the length, so, five is the optimal number of depots in the study area.

Key words: urban, emergency resource, depot, siting and layout of depots, optimizationation
