摘　　要：为兼顾安全与经济效益,有效优化运输网络,研究危险品配送中心选址和多式联运路径优化问题。基于运输方式的多样性,建立既考虑各配送中心到各需求点的多式联运最优路径,又考虑选址配给问题的选址—多式联运路径模型。将运输网络进行变形,引入目标权重和经济转化因子,将多目标规划问题转化为单目标决策问题;用Dijkstra改进算法和O-D矩阵搜索算法求解所建模型。最后,通过实例分析,验证模型和算法的有效性。结果表明,单目标优化并不能满足具有不同偏好的决策者,需要综合考虑成本和风险的目标值;不同运输方式组合运输,会影响最优路径的目标值,进而影响配送组合的目标值选择。In order to give proper attention to both economic and safety benefits and to optimize transportation network effectively, the problem of distribution center location and routing optimization for multi-modal hazardous materials transportation was addressed in this paper. Based on a variety of modes of transportation and the transportation network for deformation, a location path model of multimodal was built.The multiobjective programming problem was translated into a single objective decision problem by introducing the target weight and the economic conversion factor.The model was solved by using both a novel improved Dijkstra algorithm and an O-D matrix search algorithm. At last, through an empirical analysis to verify the validity of the model and algorithm. The research results show that the shortest path and the best distribution combination are affected by the chosen mode of transportation.
