摘　　要：近年来,危险品多式联运被广泛应用,而网络中转点由于转运量集聚,导致安全风险较高。为了有效控制危险品多式联运风险,政府可以通过中转点合理选址与分级收费,引导企业合理规划危险品运输路径。首先提出基于中转点风险分级的中转点选址与收费策略,建立危险品多式联运网络设计双层规划模型,上层为网络总风险最小化和总运输成本最小化的中转点选址与分级收费定价问题,下层为各运输事件成本最小化的运输路径规划问题。然后,使用KKT条件转换下层模型为等价约束条件,实现模型单层化,利用Gurobi求解模型。最后,通过算例表明网络风险和运输成本随着中转点数量的增加而降低,证明了中转点分级收费策略可以有效调控危险品多式联运网络风险。With the development of the economy,the demand for hazardous material transportation increases rapidly.Due to the advantages of better accessibility and economies of scale,multimodal transportation is widely used in the long-distance transportation of hazardous materials.During multimodal transportation,hazardous materials converge,stay and transit at hubs,which greatly increase the hub’s transportation risk.Therefore,in order to control the risk of multimodal transportation of hazardous materials effectively,it is necessary for government to issue hazardous material transportation permits to proper hubs and optimize the transportation network.We find that studies related to hazmat transportation network design(HTND)problem have the highest relevance to the research of this paper.The existing literatures generally control the transportation risk through a variety of policies and strategies,such as transportation banning,toll setting,flow diverting and speed limiting.These studies mainly focus on a single mode of transportation,especially road transportation,with less research on multimodal transportation.Moreover,the characteristics and constraints of hubs are nearly neglected by most of the research.Based on the constraints on the location number and maximum tolerable risk of hubs,this paper proposes a risk hierarchical toll setting strategy to minimize the risk of hazardous material multimodal transportation network.Firstly,the strategies of hub location and hierarchical toll setting based on the hub risk level are introduced.Furthermore,according to the ALARP criterion,for each hub,there are three risk levels:acceptable,tolerable and unacceptable.Secondly,a bi-level model is formulated for the hazmat multimodal transport network design.In this model,the upper layer is a hub location and hierarchical toll setting problem for minimizing the total network risk and the total transportation cost,which considers the constraints on both the maximum number and the upper bound risk of hubs.Whereas,the lower layer is
