对如何在某地区建立分级的、多灾难情景下的资源布局进行了分析,提出了双层规划的数学模型,并给出了基于粒子群算法的模型求解方法,最后通过算例验证了模型和算法的有效性。
This paper analysed the establishment of regional-level, multi-disaster scenarios emergency resource location and allocation. It proposed a bi-level programmig model and gave an effecitve algorithm based on PSO. Cases study illustrates the proposed model is very effective.
