【摘要】 提出了决策震后应急救援物资配送路径方案三步骤理论,以时间效益最大目标为原则,建模分析了不同阶段救灾物资配送特点。首先运用Monte Carb模拟技术对网络连通性进行统计判断,形成对震后可用路网的重新构建。接着运用波动理论进行通行时间评估,得到全国多个物资配送中心多条到需求灾区的基于时间权值的可用路网图。最后对多个配送路线进行综合分析,建立最长救助时间最短的配送路线选择模型。更多还原

【Abstract】 This paper proposes the framework for a 3-step model for decision-making in post-earthquake relief material distribution,with time optimization as the main concern.The paper first analyzes the characteristics of the different stages of disaster relief and recovery.Then it builds the accessible road network by statistical inference of the network connectivity after the earthquake using Monte Carb simulation and evaluates the transferring time by using wave theory and thus obtains the road network diagram weighted by access time from multiple distribution centers to the stricken area.Finally after comprehensively analyzing and comparing multiple optional routes,the paper arrives at the distribution route with the shortest possible relief time and the longest possible length of accessible road.更多还原
