论文摘要
新闻企业问题是随机库存控制中的一个重要且研究的主题。关于新闻企业问题的文献一组与从业人员经常对理论“最佳”订单数量进行判断性调整的事实有关。尽管判断性调整有时是有益的，但通常认为两种特定类型的调整是特别天真的：需求追逐和挑剔。我们讨论了这些调整在实践中的工作方式以及它们在各种环境中的暗示。我们认为，即使在某些条件下，这种幼稚的调整也可以有用。对模拟数据的实验证实了这一点。最后，我们提出了一种启发式算法，用于“调整”实践中的调整参数。
Newsvendor problems are an important and much-studied topic in stochastic inventory control. One strand of the literature on newsvendor problems is concerned with the fact that practitioners often make judgemental adjustments to the theoretically "optimal" order quantities. Although judgemental adjustment is sometimes beneficial, two specific kinds of adjustment are normally considered to be particularly naive: demand chasing and pull-to-centre. We discuss how these adjustments work in practice and what they imply in a variety of settings. We argue that even such naive adjustments can be useful under certain conditions. This is confirmed by experiments on simulated data. Finally, we propose a heuristic algorithm for "tuning" the adjustment parameters in practice.
