中文摘要：

突发事件越来越频繁地发生，对应急物资保障提出了更高的要求，好的资源布局方案对地区的资源保障程度至关重要。本文根据分级的原则，利用按照灾区分组和场景分析的方法分别确定两种级别下的各个灾区应急物资需求，同时，考虑了当级别为high时营救过程的机理分析。文章针对某个区域内的应急资源布局问题，建立了一个适于多．占、需求，多点救助的多目标规划模型，分别考虑两种级别的资源分配，以期为选址决策者进行选址和应急资源布局提供依据。求解该问题时，针对模型设计了算法，并进行了算例分析。

英文摘要：

The location and allocation of emergency resource for large-scale disaster are of paramount importance for the performance of relief resource assurance function. Based on grading rules, the demand for emergency resources in each disaster area at two levels is determined by means of grouping disaster areas and scene analysis, meanwhile, mechanism analysis of rescue process is also considered when the grade is high. To solve relief resource distribution and allocation problem, in this paper we propose a multi-objective model suitable to multi-supplier and multi-demand by respectively considering the allocation of resources at two levels, in the hope of helping decision makers effectively select sites and allocate resources. This paper explores the algorithm of the model and gives a numerical example finally.
