摘　　要：在多式联运的实际运输组织中,托运人、承运人及运输管理者等决策主体基于自身期望对运输组织方案有不同的需求,从而影响运输路径和运输方式的选择.为探究不同决策主体目标对多式联运路径优化方案的影响,构建由多个决策主体目标构成的广义费用函数,并建立以广义费用最优为目标的多式联运路径优化模型,设计符合实际情况的算例,采用理想点法并借助LINGO软件进行求解,获得不同权重组合下的多组全局最优解.In the actual transportation organization of multimodal transport,the decision-making bodies such as shippers,carriers and transportation managers have different demands for transportation organization schemes based on their own expectations,thus affecting the choice of transportation routes and modes.In order to explore the influence of different decision-making subject objectives on multimodal transport route optimization scheme,a generalized cost function composed of multiple decision-making subject objectives was constructed,and a multimodal transport route optimization model aiming at generalized cost optimization was established.A practical example was designed,and the ideal point method was used to solve the problem with the help of LINGO software.Multiple groups of global optimal solutions under different weight combinations were obtained,which provides a reference for different decision-making subjects.
