摘要:

本文面向“一带一路”背景下跨境电商企业运营实践,研究其多时段采购-多式联运协同优化策略,兼顾采购、运输、转运以及提前到货存储等成本因素。统筹安排采购、运输、存储策略,以企业整体运营成本最低为目标建立混合整数规划模型。考虑到采购成本随市场环境波动会对多式联运运输方案产生影响,本文在采购成本不确定环境下构建鲁棒优化模型,减小不确定性因素给多式联运经营者带来的风险。通过数学转化得到线性鲁棒等价模型,提升问题求解效率。然后,提出了一种混合启发式算法KIGALNS来解决这个问题。此外,通过不同规模算例实验验证了本文提出模型的正确性,以及算法和协同优化策略的有效性。最后,通过一系列数值实验表明,提前采购策略有助于节省运营总成本,鲁棒模型能较好地处理采购成本不确定等多式联运路径优化问题,在促进运输环节降本增效的同时,综合考虑采购计划以及不确定因素的影响,为企业采购-运输联合决策提供理论指导和科学方案。

Abstract:

Facing the operation practice of cross-border e-commerce enterprises under the background of the “Belt and Road”,a collaborative optimization strategy for multi-time procurement and multimodal transportation considering cost factors such as procurement, transportation, transshipment, and storage costs incurred for early arrival is proposed. A mixed-integer planning model is established to minimize the overall operating costs of cross-border e-commerce enterprises by arranging procurement, transportation, and storage strategies. Considering the fluctuation of procurement costs with the market environment, this study constructs robust optimization models under the uncertain environment of procurement costs and also develops linear robust equivalence models through mathematical transformation to improve the efficiency of problem solving.To solve the above problem, a hybrid heuristic algorithm called KIGALNS is proposed, based on the K-shortest path algorithm, Iterative Greedy algorithm (IG), and Adaptive Large Neighborhood Search (ALNS). Then, through the different size case experiments verify the validity of the proposed model, the effectiveness of the algorithm and the collaborative optimization strategy. Finally, through a series of numerical experiments show that the purchasing strategy helps to save operating cost in advance, the robust model can well deal with multimodal transport path optimization problem such as purchasing cost uncertainty, in promoting the transport link authors efficiency at the same time, considering purchasing plan and the influence of uncertain factors, provide theoretical guidance for enterprise procurement - transport joint decision and scientific solutions.
