基于免疫优化算法的应急物资储备库选址

Location Selection of Emergency Materials Reserve Warehouses Based on Immune Optimization Algorithm

为了提高应急物资利用效率和应急服务水平,针对灾害情况下应急物资运输调度的时效性特点,基于各需求点历史灾害事件数据,利用三角模糊数对历史灾害事件数进行模糊化处理;引入风险权重系数,建立应急物资储备库选址模型,并采用免疫优化算法完成求解。以安徽省应急物资储备库选址为例,验证了该模型的可行性,可为解决应急物资储备库选址问题提供理论依据和方法设计。

Reasonably selecting the location of emergency materials reserves is the key to improving the efficiency of emergency materials utilization and the level of emergency services.With and aim at the timeliness of emergency material transportation in disaster situations,based on the historical disaster event data of each demand point,the triangular fuzzy number is used to fuzzify the starting number of historical disaster events,the risk weight coefficient is introduced,and an emergency materials reserve location model is established.Immune optimization algorithm is used to complete the solution.Based on the data from Anhui Province,the feasibility of the model is verified which provides a theoretical basis and method design for solving the problem of emergency material storage location.
