The Study On Transportation Route Choice For Flammable And Explosive Dangerous Goods

As the development of economics and process of urbanization, more and more detonators and fireworks will be used in the construction of road, tunnel and mines. But there are many hidden dangers on the road transportation. How to choose a suitable transport path to avoid risk and reduce cost is got more and more attention to transport companies. So research of the mathematical model for inflammable and explosive dangerous goods transportation has important theoretical and practical significance.The status of development and research of inflammable and explosive dangerous goods transportation is introduced in the paper. The transportation system of inflammable and explosive dangerous goods is analyzed. The influencing factors of transportation route choice for flammable and explosive hazardous substance are discussed. In this paper, the transportation risk impact on route choice is emphatically analyzed. On this basis, the model of route choice of flammable and explosive hazardous substance transportation is created by combined with the route choice model of general goods transportation. The relationship among the transportation risk, the transportation time and the transportation cost is optimized in this model. The multi-objective genetic algorithm, which can be used to deal with the multi-objective relationship more efficiently and to avoid the local optimum problem, is used in the model solution. The rationality of the model and the feasibility of the algorithm are proved by the computation and analysis of the example .The conclusion of the paper can be used for reference of the hazardous substance transport enterprises to reduce the risk and the cost on route choice.
