摘　　要：对客户满意程度的考量满足运输服务高质量发展的需要,有利于客户关系的维护与企业竞争力的提升。考虑运输过程中速度的随机性,构建以包含运输成本、转运成本、时间成本、碳排放成本的总成本最小为目标,以客户时间满意度与碳补偿政策下的碳排放满意度为关键约束的多式联运路径优化随机期望值模型,采用自适应遗传算法对模型求解并进行有效性检验。以具有12个节点的多式联运网络为对象开展算例研究,分析参数变化对运输方案及成本的影响。结果表明:水路运输可以缓解成本压力并降低运输中的碳排放量,但会导致运输时间延长;碳排放配额及补偿价格的合理设置可以促使企业寻求更加经济且环保的运输方案;不同客户满意度阅值约束下的运输方案可以分为成本偏好型、时间偏好型、碳排放偏好型和随机型四类。The consideration of customer satisfaction meets the needs of high-quality development of transportation services,which is conducive to the maintenance of customer relations and the improvement of enterprise competitiveness.Considering the randomness of speed in the transportation process,a stochastic expected value model for multimodal transport path optimization is constructed,which aims to minimize the total cost including transportation cost,transshipment cost,time cost and carbon emission cost,and takes customer time satisfaction and carbon emission satisfaction under carbon compensation policy as key constraints.The model is solved by adaptive genetic algorithm and its effectiveness is tested.Taking the multimodal transportation network with 12 nodes as an example,the influence of parameter changes on transportation scheme and cost is analyzed.The results show that:1)waterway transportation can alleviate the cost pressure and reduce the carbon emission in transportation,but it will prolong the transportation time;2)The reasonable setting of carbon emission quota and compensation price can promote enterprises to seek more economical and environmental protection transportation schemes;3)Transportation schemes constrained by different customer satisfaction thresholds can be divided into four types:cost preference type,time preference type,carbon emission preference type and random type.
