摘要

当今物流业面临的最大挑战之一,就是如何应对市场的复杂性、不确定性和动态性。外部和内部因素对运营流程的效率影响很大。交叉对接配送中心是采用实时理念的一种方式。本研究提供了一种稳定方法(SA),用于解决卡车放行日期不确定情况下的多码头卡车调度问题。我们考虑了基于时间的优化目标,并提出了两种新的启发式方法,以获得可行的解决方案。为了评估 SA 的性能,我们开发并分析了另外两种不同的调度策略,即无调整策略和完美信息策略。通过广泛的计算实验,我们将 SA 与其他策略进行了比较,结果表明,该方法可以支持管理人员的日常交叉对接操作,有效处理动态和不确定数据,并快速做出正确决策。

Stability approach to CDC truck scheduling problem under uncertainty

Stability approach to CDC truck scheduling problem under uncertainty

One of the most significant challenges in logistics today is managing the complexity, uncertainty, and dynamism of the market. External and internal factors highly influence the efficiency of operations processes. Cross-docking Distribution Centers are one way of adopting a real-time philosophy. This work provides a Stability Approach (SA) for solving multi-dock truck scheduling problems under truck release date uncertainty. We consider time-based objectives for optimization and propose two new heuristics to obtain viable solutions for them. To evaluate the performance of the SA, we develop and analyze two other different scheduling policies, namely, Without Adjustments and Perfect Information. Extensive computational experiments allow us to compare SA with others and show that the methodology can support managers in their daily cross-docking operations, efficiently handling dynamic and uncertain data, and making good decisions quickly.

期刊介绍: Optimization Letters is an international journal covering all aspects of optimization, including theory, algorithms, computational studies, and applications, and providing an outlet for rapid publication of short communications in the field. Originality, significance, quality and clarity are the essential criteria for choosing the material to be published. Optimization Letters has been expanding in all directions at an astonishing rate during the last few decades. New algorithmic and theoretical techniques have been developed, the diffusion into other disciplines has proceeded at a rapid pace, and our knowledge of all aspects of the field has grown even more profound. At the same time one of the most striking trends in optimization is the constantly increasing interdisciplinary nature of the field. Optimization Letters aims to communicate in a timely fashion all recent developments in optimization with concise short articles (limited to a total of ten journal pages). Such concise articles will be easily accessible by readers working in any aspects of optimization and wish to be informed of recent developments.
