中文摘要：
针对灾后应急医疗资源配置问题，引入需求分级理念，在嵌套与非嵌套两种模式下，以运输总距离最小化为目标，建立基于需求分级的应急医疗资源配置模型。分别从服务效率与响应速度两个方面进行仿真算例研究，对比分析两种模式下应急医疗资源配置系统的整体运行水平，结果表明嵌套模式分散了低等级需求库存的内在机制，加大了其对低等级需求的服务保障。因此，在低等级需求更具重要性的应急环境中，嵌套模式下的应急医疗资源配置系统更有效率。
英文摘要：
For sake of providing satisfactory solutions for the post-disaster emergency medical re-source allocation problem, by introducing the concept of demand hierarchy, the models of medical resources allocation based on demand hierarchy were built to minimize total travel cost under two variations of nested model and non-nested model. The two models are tested and analyzed in service efficiency and response speed by simulations, and their solutions were compared on the overall oper-ation level of emergency medical resource allocation system. The results suggest that the internal mechanism of lower level demand of inventory is dispersed by nested model, and the service guaran-tee is also improved. Therefore, in an environment which has a priority for lower level demands, the nested model is a more efficient emergency medical resource allocation system.
