Dangerous goods transportation, route optimization, risk evaluation model

In recent years, with the continuous improvement of China's economic level, the business of dangerous goods transportation has also developed by leaps and bounds. Dangerous goods are goods or substances with characteristics such as explosive, flammable, radioactive, infectious, etc. These goods or substances will cause damage to personal health, social environment, etc. if improperly handled in the process of production, transportation, operation, storage, etc., and therefore need to be handled in a special way. Research on hazardous materials logistics is divided into risk assessment problem, path optimization problem, facility location problem and network design problem. Risk assessment is the basis for the latter three, and this paper focuses on reviewing the current status of research on risk assessment and route optimization of dangerous goods transportation routes. For risk evaluation, it is mainly based on risk evaluation index, risk evaluation model and relationship evaluation between risk sources. For the optimization of dangerous goods road transport routes, the main distinction is made between single mode of transport and multimodal transport, in which single mode of transport is carried out from both single and multiple objectives; multimodal transport is carried out mainly through the optimization of combined modes and algorithms, and finally the focus and weaknesses of current research are derived to provide relevant suggestions for future research directions and contents
