论文摘要

订购信号的放大和相位转移(通常称为牛头)既是对现实世界库存管理系统,库存出租和不必要的资本预订,这既导致过度压力。 Bullwhip是一个经典而又持久的问题,与库存管理中的后果回荡。对牛头的研究一直强调这种现象和杠杆行为有序模型的行为影响,以提出干预措施。但是,最近的无模型方法也取得了成功。在这项工作中,作者开发了使用两种基于行为基于模型的模型的方法以及一种无模型的双重Q-Network增强学习方法,开发了减轻斗牛的算法方法。除了探索此特定的无模型体系结构对多音供应链的实用性以及不完美的信息共享和信息延迟之外,作者还直接比较了这些基于模型和模型的方法的性能。在这样做的过程中,这项工作强调了在先前的行为运营管理文献中探索基于模型的方法而获得的见解,并强调了基于模型和模型的方法在解决行为基础供应链管理问题方面的互补性。

Amplification and phase shift in ordering signals, commonly referred to as bullwhip, are responsible for both excessive strain on real world inventory management systems, stock outs, and unnecessary capital reservation though safety stock building. Bullwhip is a classic, yet persisting, problem with reverberating consequences in inventory management. Research on bullwhip has consistently emphasized behavioral influences for this phenomenon and leveraged behavioral ordering models to suggest interventions. However more recent model-free approaches have also seen success. In this work, the author develops algorithmic approaches towards mitigating bullwhip using both behaviorally grounded model-based approaches alongside a model-free dual deep Q-network reinforcement learning approach. In addition to exploring the utility of this specific model-free architecture to multi-echelon supply chains with imperfect information sharing and information delays, the author directly compares the performance of these model-based and model-free approaches. In doing so, this work highlights both the insights gained from exploring model-based approaches in the context of prior behavioral operations management literature and emphasizes the complementary nature of model-based and model-free approaches in approaching behaviorally grounded supply chain management problems.
