Route Optimization of Hazardous Material Railway Transportation Based on Conditional Value-at-Risk Considering Risk Equity

Year: 2025

Type: article

Abstract: Hazardous materials events by rail have the characteristics of small probability and even higher consequence than other modes. In response to these characteristics, we have adopted conditional value-at-risk into the risk assessment of hazardous materials railway transportation, which can flexibly realize the configuration decisions from risk neutrality to risk aversion. Moreover, this paper not only focus on risk reduction, but also pay more attention to reasonable risk distribution, which means risk equity for people in the entire environment. In this paper, a new model is proposed by adding risk equity goal to the traditional conditional value-at-risk assessment, and route decision-making can be optimized through this model, then an algorithm based on k-shortest path algorithm is given to solve the problem. Finally, the validity of the model and algorithm is verified based on the example of hazardous materials railway transportation network in the Yangtze River Delta. This research can provide decision support for enterprises to optimize the route of railway transportation of hazardous materials, and can also provide decision support for the government to carry out detailed safety management of railway transportation of hazardous materials.
