摘要:: 根据联通图与线性规划相结合的原理,构建了一种震后灾民转移安置模型。模型采用Floyd算法计算了灾民点到安置点最短路径,采用约束条件下的线性规划计算了最优安置人数,使得震后灾民转移路径最短,用时最少,安置人数分配最优。以云南省建水县临安镇为例,在城区遭遇Ⅷ度破坏的情况下,对灾民转移安置路径和人数分配进行演算,得到了优化的灾民转移安置方案,验证了模型的可行性。

Abstract:: Based on the connectivity map and the linear planning,this paper constructs a model of post-earthquake resettlement for the earthquake-hit civilians.The model uses the Floyd algorithm to calculate the shortest route from the residential areas to the emergency shelters and uses the linear planning under the condition of constraints to calculate the optimal number of resettlements,so as to get the shortest evacuation route,the least evacuation time,and the optimized allocation of the resettled people.The model proposed in this paper is applied to the study of Lin'an Town,Jianshui County of Yunnan Province in the case of being hit by Intensity Ⅷ in an earthquake event.The route and the number of the resettled people are calculated with the model,and the optimal people resettlement scheme is obtained.The model proves feasible.
