道路修复条件下灾后应急资源配送LRP研究

灾后道路中断、道路通行可靠性减弱从根本上影响着救援工作的效率,文章通过在应急资源配送定位路径问题的基础上考虑对障碍道路进行修复。通过构建应急设施定位、障碍道路修复以及配送路径选择的综合优化模型,以应急救援的时间总成本最小为目标。集中考虑应急设施定位选址、修复障碍道路和选择配送路径的基础上,以时间总成本最小为目标函数,通过结合相关案例仿真与数据分析的基础上运用多吸引粒子群优化算法对模型进行求解,以期为灾后道路选择、提升道路通行可靠性和应急物资配送效率提供借鉴于理论指导。

Research on Location-routing Problem in Emergency Resource Delivery Based on the Road Repair

Road damage, bridge collapse and the high risk of road network are the typical characters of emergency supplies distribution in the disaster. In this paper, distribution center location, road damage and traffic reliability are introduced to describe the effects on the distribution of emergency resource. Emergency resource distribution reliability path optimization model is established to minimize the rescue time. Then a Particle Swarm Optimization algorithm has been used to solve the model. With the help of empirical analysis in combination with an example, the model is proved suitable, which has a practical significance according to the distribution of emergency supplies under uncertain road network.
