在本文中，我们考虑一个供应链模型，由一个单一的产品，一个供应商，和多个零售商。零售商的需求是随机的，但是固定的。每个零售商根据众所周知的（Q，R）策略向供应商下订单。我们假设供应商有关于需求的在线信息，以及产品在每个零售商的库存活动，并在做出订单/补货决策时使用这些信息。首先，我们提出了一个补充政策的供应商，其中包括零售商的库存位置的信息。然后，我们提供了一个准确的分析，这种系统的操作措施。假设库存/补货决策是集中的系统，我们比较我们的模型的性能与那些不使用信息在他们的决策，即，系统使用安装库存政策，通过数值实验。根据我们的数值结果，我们确定的参数设置下，信息共享是最有益的。
In this paper, we consider a supply-chain model consisting of a single product, one supplier, and multiple retailers. Demand at the retailers is random, but stationary. Each retailer places her orders to the supplier according to the well-known (Q, R) policy. We assume that the supplier has online information about the demand, as well as inventory activities of the product at each retailer, and uses this information when making order/replenishment decisions. We first propose a replenishment policy for the supplier, which incorporates information about the inventory position of the retailers. Then, we provide an exact analysis of the operating measures of such systems. Assuming the inventory/replenishment decisions are made centrally for the system, we compare the performance of our model with those that do not use information in their decision making, namely, systems that use installation stock policies via a numerical experiment. Based on our numerical results, we identify the parameter settings under which information sharing is most beneficial.
