摘　　要：疫情期间保证应急物资的配送是严防严控的重要环节,考虑到新冠疫情传染性强且具一定致死率,新冠应急物资在配送方面应注重时效性。在满足载重量和需求量以及尽可能满足时间窗要求的基础上建立基于变异蚁群算法的物流配送路径优化模型,并通过实例验证算法可行性。从求解过程和结果来看本研究提出的模型和算法找到的路径是较优的。Ensuring the distribution of emergency materials during the epidemic is an important part to control the epidemic.Timeliness should be paid attention to in the distribution of emergency supplies considering to highly contagious and lethal of the COVID-19 epidemic.To meet the time window requirements as much as possible,a logistics distribution route optimization model based on the mutation ant colony algorithm is established,and the feasibility of the algorithm is verified through examples.From the results,the path found by the model and algorithm proposed in this study is better.
