摘要: 伴随冷链物流市场快速发展与冷藏集装箱多式联运重要性提升,针对冷链物流中冷藏集装箱多式联运的中转时间不确定性问题,本文构建一个以运输总成本最小化和时间效率比最大化为目标的多目标路径优化模型。采用三角模糊数表征中转时间不确定性,通过机会约束规划实现模糊模型向确定性模型的转化。此外,本文设计了一种自适应交叉与变异概率的改进非支配排序遗传算法(NSGA-II)对模型进行求解,并与传统的NSGA-II算法进行对比。结果表明:本文模型能够有效降低运输成本,提高运输时效性,改进的NSGA-II算法在解集规模和收敛速度方面表现出显著优势,较传统算法分别提升16.2%和21.7%。进一步对铁路运价进行灵敏度分析显示:当铁路运价降低至40%时,运输方式全部转为铁路运输,此时运输总成本降低19.8%,时间效率比提升49.0%。本文为冷链物流企业提供了科学的路径选择决策支持,有助于应对中转时间不确定性挑战,优化冷藏集装箱多式联运路径。

Abstract: Accompanied by the rapid development of cold chain logistics market and the increase in the importance of intermodal transport of reefer containers, a multi-objective path optimization model is constructed with the objectives of minimizing the total transportation cost and maximizing the ratio of time efficiency, which aims at the uncertainty problem of transit time during the intermodal transport of reefer containers in cold chain logistics. A triangular fuzzy number is used to characterize the uncertainty of transit time, and then the transformation of a fuzzy model to a deterministic model is realized through the opportunity constrained planning. In addition, an improved NSGA-II algorithm with adaptive crossover and variance probabilities is designed to solve the model and further compared with the traditional NSGA-II algorithm. The results show that the constructed model can effectively reduce the transportation cost and improve the transportation timeliness. The improved NSGA-II algorithm shows significant advantages in terms of solution set size and convergence speed, which are 16.2% and 21.7% higher than those of the traditional algorithm, respectively. Further the sensitivity analysis of railroad tariffs shows that when the railroad tariffs are reduced to 40%, all transportation modes would switch to railroad transportation. The total cost of transportation would be reduced by 19.8% and the time efficiency ratio is improved by 49.0% at that time. This study provides scientific decision support for cold chain logistics enterprises to choose the path, which helps to meet the challenge of transit time uncertainty and optimizes the intermodal transport path of reefer containers.

Key words: integrated transportation, path optimization, improved second-generation non-dominated sorting genetic algorithm; refrigerated cargo, transfer time uncertainty
