摘　　要：探讨了影响易燃易爆危险物品运输路径选择的影响因素,重点分析了运输风险对路径选择的影响,建立了符合安全需求和经济的易燃易爆物品道路运输路径选择决策模型,在模型求解方面采用了可以较好地处理多目标之间关系的多目标遗传算法.最后,通过算例对模型进行验证.验证结果表明了该模型的合理性及其算法的可行性.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. The transportation risk impact on route choice is emphatically ana- lyzed. On this basis, the model of route choice of flammable and explosive hazardous substance transportation is presented by combining with the route choice model of general goods transportation. The multi-objective genetic algorithm, which can be used to deal with the multi-objective relationship more efficiently, is used in the model solution. The rationality of the model and the feasibility of the algorithm are proved by the example.
