摘要 针对震后紧急响应阶段的应急物流系统优化问题,建立了一个两级设施定位-运输路线安排问题模型(LRP),据此进行应急设施定位-分配和救援物资运输路线安排决策.根据该模型的特点,提出一种基于两阶段分解思想的"三角"启发式算法,对算法的复杂性进行了分析,并与改进遗传算法进行了对比研究.算例分析结果表明,该模型和算法可以解决震后应急物流系统中的LRP,所设计的"三角"启发式算法性能优越,具有较高的运算效率. To optimize emergency logistics system for post-earthquake emergency relief response,a two-echelon Location-Routing Problem(LRP) model was developed to decide emergency facility location-allocation and vehicle routes for relief materials delivery.According to the attributes of the model,a 'triangle' heuristic algorithm based on two-phase decomposition was proposed.The complexity of the algorithm was analyzed,and the heuristic algorithm was compared with an improved genetic algorithm. The computational results of a numerical example show that the model and algorithm can resolve LRP in post-earthquake emergency logistics system,and the advantage of the 'triangle' heuristic algorithm in computational efficiency.
