摘要: 易腐货物通过现有多式联运网络的运输显著增加,而易腐货物的严格质量要求推动了对冷藏集装箱高效转运的关注。因此,本文提出一种多式联运路径优化模型,目标是使平均成本和质量损失最小化;在考虑铁路装载需求的不确定性下,探讨制冷供应和失效对质量退化的影响;采用非支配排序遗传算法(NSGA-II),以安特卫普港进口苹果到兰州为研究对象,进行数值实验。结果表明,尽管冷藏失效时间很短,但与供应状态相比,仍可能导致高达40%的质量下降。本文为易腐产品提供了可靠的运输解决方案,建议将节点单次停留时间限制在保持新鲜度总时间的11%以下。对于中转站运营商来说,缩短冷藏故障持续时间和提高站点内的服务水平成为吸引托运人的有效方法。

Abstract: The transportation of perishable cargoes through the existing intermodal freight network has increased significantly. The focus on efficient transshipment of refrigerated containers has been driven by the strict quality requirements of perishable goods. Therefore, an intermodal transportation path optimization model is proposed aiming to minimize the average cost and quality degradation. Considering the uncertain of railway loading demand, the impacts of refrigeration supply and failure on quality degradation are explored. The non-dominated sorting genetic algorithm (NSGA-II) is adopted. A numerical experiment is conducted for the import of apples from the Port of Antwerp to Lanzhou. Results indicate that, although refrigeration failure time is brief, it can lead to the quality degradation of up to 40% compared to the supply state. The research provides robust transportation solutions for perishable products by recommending that the duration of single stops at nodes be limited to less than 11% of the total time to preserve freshness. For transfer station operators, shortening the duration of refrigeration failures and enhancing service levels within stations become as effective methods to attract shippers.
