摘要:

过去几年,城市物流服务发生了范式转变;对实时、即时移动和交付服务的需求不断增长。这对物流服务提供商提出了新的挑战,因为潜在的随机动态车辆路径问题(SDVRP)需要预期的实时路径行动。搜索有效的路由行动的组合行动空间本身是一个复杂的任务混合整数规划(MIP)众所周知的运筹学界。考虑到未来的动态性和不确定性,评估此类行动的有效性的挑战增加了这种复杂性,这是计算机科学界众所周知的强化学习(RL)的潜在理想案例。为了解决SDVRPs,需要两个社区的联合工作,但正如我们所展示的,基本上不存在。两个社区都注重各自的优势,留下改进的潜力。我们的调查报告强调了这两个社区的研究潜力。我们指出了SDVRP中目前存在的障碍,并指导采取联合方法来克服这些障碍。

英文摘要:

There has been a paradigm-shift in urban logistic services in the last years; demand for real-time, instant mobility and delivery services grows. This poses new challenges to logistic service providers as the underlying stochastic dynamic vehicle routing problems (SDVRPs) require anticipatory real-time routing actions. Searching the combinatorial action space for efficient routing actions is by itself a complex task of mixed-integer programming (MIP) well-known by the operations research community. This complexity is now multiplied by the challenge of evaluating such actions with respect to their effectiveness given future dynamism and uncertainty, a potentially ideal case for reinforcement learning (RL) well-known by the computer science community. For solving SDVRPs, joint work of both communities is needed, but as we show, essentially non-existing. Both communities focus on their individual strengths leaving potential for improvement. Our survey paper highlights this potential in research originating from both communities. We point out current obstacles in SDVRPs and guide towards joint approaches to overcome them.
