This article develops a hub-and-spoke architecture for a parcel delivery system using a network that includes a distribution centre and several cross-dock facilities. Several real-world assumptions, including an electric truck fleet, mobile charging station, third-party logistics, capacity constraints, last-mile deliveries and customer dissatisfaction, are incorporated in this problem. Besides, because of the high complexity of the problem, a novel matheuristic algorithm based on the combination of the fix-and-relax algorithm (FARA) and genetic algorithm (GA), namely Mb-FARGA, is developed to solve large-sized instances. A comprehensive computational analysis is accomplished to validate the proposed mathematical models and evaluate the performance of the Mb-FARGA method. According to the results, the Mb-FARGA method demonstrates a very favourable performance. Moreover, the results show that considering a distribution centre with appropriate capacity in the cross-docking system is an excellent strategy to enhance customer satisfaction, improve the system’s performance and reduce capacity shortages.

使用交叉配送策略的包裹递送系统的中心辐射式架构

本文使用包含一个配送中心和多个跨站台设施的网络为包裹递送系统开发了一个中心辐射式架构。这个问题包含了几个现实世界的假设,包括电动卡车车队、移动充电站、第三方物流、容量限制、最后一英里交付和客户不满。此外,由于问题的高度复杂性,开发了一种基于固定和松弛算法(FARA)和遗传算法(GA)相结合的新型数学算法,即Mb-FARGA,用于解决大型实例. 完成了全面的计算分析以验证所提出的数学模型并评估 Mb-FARGA 方法的性能。根据结果​​,Mb-FARGA 方法表现出非常好的性能。此外,结果表明,在越库系统中考虑具有适当容量的配送中心是提高客户满意度、提高系统性能和减少容量短缺的极好策略。
