摘要
为提升突发事件下应急物流的快速应对能力,提高物流资源配置效率,基于区域应急物流网络,提出突发事件下实现区域物流资源优化配置的直达路径配置策略、核心区域集散节点配置策略和混合调整配置策略3种调整策略。基于3种调整策略,以总运输时间最短为目标,构建突发事件下区域物流资源优化配置模型,结合模型决策变量的特点,运用改进免疫克隆算法进行求解,并通过实例对模型及算法进行验证。结果表明:模型及算法具有良好的适应性,可为区域物流资源的优化配置提供决策依据。
The optimal allocation of regional logistics resources plays an important role in improving the ability of rapid response to emergencies and improving the efficiency of logistics resources allocation.This paper proposed three adjust tactics for rapid response allocation of regional logistics resources based on regional logistics network.The three adjust tactics included direct path configuration tactic,core region transfer node configuration tactic and mix adjust configuration tactic.Considered adjust tactics,the optimization model of response allocation of regional logistics resources under emergency events was built with the objective function that total transportation time was minimal.The improved immune clonal selection algorithm was used to resolve this model.The real-world example was used to verify the effectiveness of the proposed model and algorithm.The result shows the strong adaptability of the model and algorithm which can provide reference for optimization allocation of regional logistics resources.
