摘　　要：针对危险品运输车辆的载货量变化对于路径风险影响的问题,建立了最优化危险品运输车辆路径的新模型,对车辆访问需求点的路线进行决策。考虑了载货量的动态变化和配送服务时间窗,构建了多目标的危险品运输路径优化模型。采用NSGA2的非支配排序的方法进行种群选择,对问题进行求解。结果表明,考虑载货量的风险度量方式可以提供风险多样化的决策方案,以满足不同决策者的风险偏好。In this paper,aiming at the problem of the influence of the change of the loading capacity of hazardous materials transport vehicles on the path risk,a new model of optimizing the route of hazardous materials transport vehicles is established to make decisions on the routes of vehicles visiting demand points.Considering the dynamic change of cargo load and the service time window,the optimization model of hazardous material transportation route is constructed to multi-objective.In this paper,the non dominated sorting method of NSGA2 is used to select the population and solve the problem.The results show that the risk measurement method considering the cargo volume can provide a diversified decision-making scheme to meet the risk preference of different decision-makers.
