Distribution route multi-objective optimisation of dangerous goods considering the time reliability

摘要

>In view of the increasingly prominent security issues of dangerous goods transportation, a distribution route optimisation model of dangerous goods is proposed. Firstly, the travel time reliability model and transportation risk model are established respectively. Besides, the multi-objective optimisation model of dangerous goods route is built based on the travel time reliability. Secondly, the genetic algorithm is designed to solve the optimisation model. Finally, a numerical case is used to verify the feasibility and effectiveness of the model and algorithm. Study result shows that the distribution route optimisation model of dangerous goods has an important theoretical value and practical significance of reducing the accident risk, increasing the time reliability and ensuring dangerous goods transportation safety.
