This study explores the relationship between a retailer's product returns processing structure and Multi‐Echelon inventory system performance under cross‐channel and same‐channel product returns policies with nonstationary demand. Our research contributes to the growing body of reverse logistics literature, offering insight into how a retailer's logistical returns management strategy can impact inventory effectiveness in cross‐channel retail environments. Adopting a contingency framework, we develop research hypotheses which we test through experimentation on a Multi‐Echelon retail inventory system within a discrete‐event simulation. Model parameters are derived from data collected from a large U.S. retailer of consumer durable and nondurable goods. We find an amplifying effect of a cross‐channel returns policy on the positive relationship between a decentralized returns processing structure and inventory effectiveness. Further, through our analysis of nonstationarity in demand and resulting returns, we uncover strong main and interaction effects that seasonal demand variation can have on inventory outcomes, even under only moderate levels of seasonality. Our results highlight the need for firms to align logistical structures for returns processing with the returns policy and the external environment, while also lending credence to calls within the logistics literature for improved modeling of nonstationary demand in inventory management research.

具有跨渠道产品退货的多级零售库存的仿真模型

本研究探讨了具有非平稳需求的跨渠道和同渠道产品退货政策下零售商的产品退货处理结构与多级库存系统性能之间的关系。我们的研究为逆向物流文献的增长做出了贡献,从而洞察了零售商的后勤退货管理策略如何影响跨渠道零售环境中的库存有效性。通过采用权变框架,我们开发了研究假设,并通过在离散事件模拟中在多级零售库存系统上进行的实验进行了测试。模型参数来自于一家大型美国耐用和非耐用商品零售商的数据。我们发现跨渠道退货政策对分散式退货处理结构与库存有效性之间的正相关关系具有放大作用。此外,通过对需求和产生的回报的非平稳性的分析,我们发现即使在中等季节性水平下,季节性需求变化也会对库存结果产生强烈的主要和互动影响。我们的结果突出表明,公司需要使退货处理的物流结构与退货政策和外部环境保持一致,同时也要向物流文献中的呼叫提供依据,以改进库存管理研究中的非平稳需求模型。通过对需求和产生的收益的非平稳性的分析,我们发现即使在中等季节性水平下,季节性需求变化也会对库存结果产生强大的主要和互动影响。我们的结果突出表明,企业需要使退货处理的物流结构与退货政策和外部环境保持一致,同时也要向物流文献中的呼叫提供依据,以改进库存管理研究中的非平稳需求模型。通过对需求和产生的收益的非平稳性的分析,我们发现即使在中等季节性水平下,季节性需求变化也会对库存结果产生强大的主要和互动影响。我们的结果突出表明,公司需要使退货处理的物流结构与退货政策和外部环境保持一致,同时也要向物流文献中的呼叫提供依据,以改进库存管理研究中的非平稳需求模型。
