基于CVaR的危险品公铁联运路径选择研究
Routing the Road and Railway Intermodal Transportation of Hazmat Based on CVaR
摘要
Abstract
Road and railway intermodal transportation has been playing an important role in multimodal transportation 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 proposed 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 proposed model and algorithm can give the transportation route and transportation mode with minimum road and railway intermodal transportation risk of hazmat in the transportation network quickly according to the decision maker'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 intermodal transportation of hazmat.关键词
