摘 要: 由于各种自然灾害和公共卫生事件频发,世界各国加大了对应急物资的采购、存储和调运方案的研究,旨在建立高效的救援物流系统。结合以往文献中有关应急状态下物资运输的模型和非常规物流中车辆运输的特殊性,运用多式联运和路网的脆弱性理论,建立应急物资全程调拨时运输方式和路径选择问题的综合模型,设计改进的蚁群算法,结合算例说明当运输路径及其流量发生改变时应急物资运输路径的变化情况。

Abstract:Because of frequent occurrence of natural disasters and public health events,study on the purchasing,storage and allocation plan for emergency materials was enforced all over the world,which aims at establishing high efficient rescue logistic system.Referring to material transportation models in emergent state and the specialty of vehicle transportation in irregular logistics which were proposed in many papers,multimodal transportation theory and network vulnerability theory were applied to establish compositive model of transport mode and path selection for the whole course allocation of emergency materials.The modified ant colony algorithm was designed which combines with an example to explain the change conditions according to the change of transport path and its flow.

 

Key words: emergency material; transport path; multimodal transportation; network vulnerability; ant colony algorithm
