供应链管理的一个重要方面是供应商基础的优化配置。当每个供应商的产品产量是随机的时，我们建立了一个模型来确定最优批量和最优供应商数量。虽然来自大量供应商的小订单可以减少产量的不确定性，但与每个供应商相关的固定成本会给供应商太多带来惩罚。这是我们的模型解决的关键权衡。我们研究供应商既相同又不相同的情况。
An important aspect of supply chain management is the optimal configuration of the supplier base. We develop a model to determine optimal lot sizes and the optimal number of suppliers when the yield of the product delivered from each supplier is random. While small orders from a large number of suppliers can reduce yield uncertainty, fixed costs associated with each supplier provide a penalty for having too many suppliers. This is the key tradeoff addressed by our model. We look at the cases when the suppliers are identical as well as nonidentical.
