In this paper, we study the duration-minimizing time-dependent vehicle routing problem with time windows (DM-TDVRPTW), where time-dependent travel times represent different levels of road congestion throughout the day. The departure time from depot becomes an important decision to reduce the route duration. We provide an alternative arc-based mixed-integer programming model with explicit arc time zone index. For larger scale instances, we extend the segment-based evaluation method to speed up the feasibility check of a given vehicle route. It is thereafter incorporated to implement an efficient hybrid adaptive large neighborhood search with tabu search (ALNS-TS) algorithm, to explore both feasible and infeasible solution spaces. The ALNS-TS exploits the strength of diversification in ALNS through adaptive control of neighborhood size, as well as the strength of intensification in TS by limiting the maximum number of steps allowed without improvement. Related parameters are tuned using an automatic configuration tool to determine the best set of configurations. The computational results demonstrate its excellent performance on the benchmark instances proposed by Dabia et al. (2013), obtaining optimal solutions for all instances with 25 customers and improving best-known solutions for 36 instances with 50 and 100 customers. Computational experiments are also conducted to evaluate the effectiveness of the algorithm on an extra set of large scale instances and on the simplified VRPTW instances.

具有时间窗的时变车辆路径问题的混合算法

在本文中,我们研究带有时间窗(DM-TDVRPTW)的持续时间最小的时间依赖性车辆路径问题,其中时间依赖性旅行时间代表全天不同程度的道路拥堵。从仓库出发的时间成为减少路线持续时间的重要决定。我们提供了一个带有显式弧时区索引的基于弧的替代混合整数编程模型。对于较大规模的实例,我们扩展了基于细分的评估方法,以加快对给定车辆路线的可行性检查。此后将其合并起来,以实现具有禁忌搜索的高效混合自适应大邻域搜索(ALNS-TS)算法,以探索可行和不可行的解决方案空间。ALNS-TS通过对邻域大小的自适应控制来利用ALNS多样化的优势,以及通过限制允许的最大步数而不改进而增强TS中的强度。使用自动配置工具调整相关参数,以确定最佳的配置集。计算结果证明了其在Dabia等人提出的基准实例上的出色性能。(2013年),为25个客户的所有实例获取最佳解决方案,并为50个客户和100个客户的36个实例改进最著名的解决方案。还进行了计算实验,以评估该算法在一组额外的大型实例和简化的VRPTW实例上的有效性。使用自动配置工具调整相关参数,以确定最佳的配置集。计算结果证明了其在Dabia等人提出的基准实例上的出色性能。(2013年),为25个客户的所有实例获取最佳解决方案,并为50个客户和100个客户的36个实例改进最著名的解决方案。还进行了计算实验,以评估该算法在一组额外的大型实例和简化的VRPTW实例上的有效性。使用自动配置工具调整相关参数,以确定最佳的配置集。计算结果证明了其在Dabia等人提出的基准实例上的出色性能。(2013年),为25个客户的所有实例获得最佳解决方案,并为50个客户和100个客户的36个实例改进最著名的解决方案。还进行了计算实验,以评估该算法在一组额外的大型实例和简化的VRPTW实例上的有效性。
