摘　　要：为有效开展突发事件背景下的应急物资储备库选址工作。首先,考虑应急物资到达需求点的时间,以时间满意度最大和选址成本最小为目标,建立双目标混合整数规划模型;然后,在免疫算法中引入模拟退火算子,结合两者优点构建免疫模拟退火算法;最后,将位于四川省龙门山断裂带上的29个县市的汶川地震数据作为算例,求出选择2~8个应急物资储备库的选址方案并对比不同结果。结果表明:免疫模拟退火算法具有稳定性,选址数量为8的方案比之前研究时间满意度提升15.8%,选址成本减少26268元。并且求得结果时间满意度与选址成本均优于免疫算法和模拟退火算法,有利于应急物资储备库选址。The purpose of this paper aimed to effectively carry out the site selection of emergency material storage under the background of emergencies.Firstly,considering the time when emergency supplies arrive at the demand point,a bi-objective mixed integer programming model was established with the goal of maximizing time satisfaction and minimizing location cost.Then,the simulated annealing operator was introduced into the immune algorithm,and the immune simulated annealing algorithm was constructed by combining the advantages of the two operators.Finally,taking the Wenchuan earthquake data of 29 counties and cities located in the Longmenshan fault zone in Sichuan Province as an example,the site selection scheme for selecting 2-8 emergency material storage warehouses was worked out and the results of different schemes were compared.The results show that the immune simulated annealing algorithm is stable,and the time satisfaction of the scheme with 8 locations is increased by 15.8%compared with the previous study,and the location cost is reduced by 26268 yuan.The time satisfaction and location cost of the results obtained are better than those of immune algorithm and simulated annealing algorithm,which is conducive to the location of emergency material storage.
