摘要：公铁联运在危险品的多式联运中扮演着重要角色,为了降低危险品公铁联运风险,提高危险品公铁联运的安全性,危险品公铁联运的路径选择至关重要。本文运用条件风险价值(CVaR)理论,在对危险品公铁联运网络进行变形的基础上构建了考虑决策者风险规避程度的危险品公铁联运路径选择模型,设计了求解该模型的算法,并进行了算例分析。研究结果表明:通过该模型及其算法,可根据决策者对所需运输的危险品的运输风险规避程度,在危险品公铁联运网络中快速地选出使危险品公铁联运风险最小的运输路径和运输方式;决策者的风险规避程度会对危险品公铁联运过程中的运输路径和运输方式的选择产生重要影响。
Road and railway intermodal transportation has been playing an important role in multimodal transpor- tation of hazmat. In order to reduce the transportation risk and ensure the transportation safety, routing the road and railway intermodal transportation of hazmat is utmost important. In this paper, the theory of conditional value at risk（CVaR） is taken, and a route selection model considering the decision maker＇ s risk-averse level is pro- posed based on the road and railway intermodal transportation network transformation. Furthermore, an algorithm used to solve the proposed model is developed and an illustrative example is given. The results show that the pro- posed model and algorithm can give the transportation route and transportation mode with minimum road and rail- way intermodal transportation risk of hazmat in the transportation network quickly according to the decision mak- er＇ s risk-averse level of the hazmat transportation risk. The decision maker＇ s risk-averse level has significant impact on the selection of transportation route and transportation mode in the process of road and railway inter- modal transportation of hazmat.
