摘 要: 由于危险品运输的特殊性质,在危险品运输路径选择过程中,需要考虑更多的因素,因此提出基于多目标的路径优化模型,通过运输风险、危险平均后果及总后果全面考虑运输中的危险,并将风险、运距及费用目标抽象得到类似广义费用的综合表达形式,使得影响因素影响程度的确定具有更强的灵活性以及适用性;对于综合目标模型采用Dijkstra算法求解,该方法简便易算具有很强操作性,最后用算例验证了方法的科学可行性. As for hazardous material road transportation,due to its special quality and susceptible to be affected by more factors,this paper propose a model based on multi-objective optimization.By weighting each objective to get a similar generalized cost expression,makes the function of influencing factors more flexibility and applicability;and by applying global optimization algorithm to optimize the path,this method is simple and easy to be calculated,which will provide a more operable model for the optimization problem of hazardous material road transportation.Finally,the feasibility of the method is proved by the given example.
